XML schemas provide a more powerful way to define the structure and content of XML documents compared to DTDs. Schemas support data types, namespaces, and more complex definitions of elements and attributes. The main elements used in schemas are:
1. <xs:schema> which defines the root element and namespace for a schema.
2. <xs:element> and <xs:attribute> which define elements and attributes with attributes like name, type, and occurrence.
3. <xs:complexType> which defines complex element types with child elements, attributes, and mixed content.
Schemas allow precise specification of XML documents' structure through elements, attributes, data types and occurrence to enable validation of
The document discusses XSLT (Extensible Stylesheet Language Transformations), which is used to transform XML documents into other formats like HTML, PDF, etc. It explains some key XSLT elements and concepts:
1. The <template> element matches XML elements and applies styles.
2. The <value-of> element inserts node values from the XML.
3. The <for-each> element loops through multiple occurrences of an element.
It also covers selecting attributes with XPath, using conditional elements like <if> and <choose>, and predicates to filter nodes. XSLT allows XML data to be transformed and presented in different formats.
This document discusses validating XML documents using DTDs. It explains that DTDs define the structure and elements of an XML document. Elements, attributes, and their content must be declared in the DTD. Elements can have text, child elements, or mixed content. Attributes have types like ID, enumerated, and default values like required or implied. The document provides examples of declaring elements, attributes, and their types in a DTD to validate an XML file.
The document discusses combining XML vocabularies using namespaces to avoid name collisions. It describes:
1) Declaring a namespace by adding an xmlns attribute to an element, which assigns a unique URI to the namespace and associates elements with a prefix.
2) Applying namespaces to elements by inserting the namespace prefix before element names. This identifies which namespace each element belongs to.
3) Using default namespaces, which omit the prefix and assume child elements belong to the namespace declared on the parent element.
XML is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. The document describes how to create an XML document, including defining elements, attributes, and hierarchies. It also covers linking XML documents to style sheets to format the presentation of the data.
This document provides an introduction to XSLT by defining key terms like XML, XML Namespaces, HTML, XHTML, XPath, and describing what XSLT is and how it transforms XML documents into other formats like HTML. It explains some of the core components of XSLT including using XPath to select nodes in an XML document and templates defined using xsl:template that transform matched parts of the source XML.
This document provides an overview of XML DTD and Schema. It defines key terms like well-formed, valid, DTD and describes how a DTD is used to define element types and attributes. It also explains different DTD rules like EMPTY, ANY, #PCDATA. The document then covers XML Schema elements, data types, and how to declare elements, attributes and complex/simple types in a schema.
XML Schema provides a way to formally define and validate the structure and content of XML documents. It allows defining elements, attributes, and data types, as well as restrictions like length, pattern, and value ranges. DTD is more limited and cannot validate data types. XML Schema is written in XML syntax, uses XML namespaces, and provides stronger typing capabilities compared to DTD. It allows defining simple and complex element types, attributes, and restrictions to precisely describe the expected structure and values within XML documents.
The document discusses schemas and their purpose in specifying the structure and constraints of an XML document. It provides examples of things that cannot be done with DTDs but can be done with schemas, such as constraining text values.

XML is a markup language used to carry and store data. It was designed to transport data rather than display it. XML tags are defined by the author rather than being predefined. XML documents form a tree structure with a root element and branching child elements. For a document to be considered valid XML, it must follow syntax rules like having matching open and close tags and properly nested elements.
XSLT is used to transform XML documents into other XML documents or HTML. It uses XPath to navigate XML documents. Templates are used to define transformation rules that are applied when nodes are matched. Common elements used in XSLT include value-of to extract node values, for-each for loops, apply-templates to apply templates to child nodes, and copy to duplicate nodes in the output. Conditional logic can be added using elements like if, choose, when and otherwise.
XML schema defines the structure and elements of an XML document. It defines elements, attributes, and data types. Elements are the building blocks and can be simple types like strings or integers, complex types that can contain child elements, or global types that can be reused. Attributes provide additional information for elements. An XML schema uses tags like <xs:element> and <xs:complexType> to define the document structure.
An XML schema defines the structure and elements of an XML document. It is an XML-based alternative to DTDs that allows defining element types, attributes, data types, defaults and restrictions. Schemas support namespaces, data types, extensibility and are written in XML, allowing the use of XML tools. Complex elements can contain child elements, text or both.
XSLT is used to transform XML documents into other formats. It uses XSLT style sheets, which contain rules that are applied by an XSLT processor to the XML input. Some key capabilities of XSLT include converting XML to HTML, sorting and filtering data, and using conditional logic. Template rules define how to retrieve element values from the XML and output them. Loops, conditional statements, and multiple sorting allow complex transformations of the XML data.

- XSLT transforms an XML source tree into an XML result tree
- It uses templates and applies templates to elements to transform the document
- Common elements include <xsl:template>, <xsl:value-of>, <xsl:for-each>, <xsl:if>, <xsl:choose>, and <xsl:apply-templates>
- XSLT is supported by browsers through built-in or third
This document provides an overview of XSLT, including:
- What XSLT is and why it is used to transform XML documents by converting schemas, rearranging data for formatting, etc.
- How to program with XSLT using templates, calls to templates, value-of elements to extract values, foreach loops, sort elements, if/choose conditional statements.
- Examples are provided and it discusses using XSLT in a Polaris application. Strategies for writing XSLT include using consistent styles, using shorter patterns over complex paths, and using value-of and if statements over complex paths when possible.
XSLT is used to transform XML documents into other formats like HTML. It uses an XML document and an XSL stylesheet to perform the transformation. The XSL stylesheet contains templates that are applied to the XML data to output a new formatted document. Common XSL elements include xsl:value-of to output node values, xsl:for-each for loops, and xsl:apply-templates to apply templates to child nodes. XSLT provides powerful tools for transforming XML but requires careful debugging due to its complexity.
XSD (XML Schema Definition) is used to describe and validate the structure and content of XML data. It provides more powerful capabilities than DTD. XML Schemas support data types, restrictions on elements and attributes, and namespaces. With XML Schema, groups can agree on standards for exchanging data and documents can be verified. XML Schemas use XML syntax, so they can be edited, parsed, and manipulated like any other XML document. The purpose of an XML Schema is to define the legal building blocks of an XML document, such as elements, attributes, and their structure.
This document provides an overview of XML Schema Definition (XSD). It discusses that XSD is used to describe and validate the structure and vocabulary of an XML document. It then provides an example of a simple XSD code and explains some of its key features, such as being extensible, supporting data types and namespaces. It also outlines the basic syntax of an XSD, including the required <schema> root element and optional attributes like targetNamespace. Finally, it demonstrates how to reference an external XSD from an XML document using schemaLocation.

The Mystical Principles of XSLT: Enlightenment through Software Visualizationevanlenz
The mature XSLT developer has an inner seeing about how a stylesheet works that can seem almost mystical to an outsider. But demystification is possible using an XSLT visualizer, making the structure of a transformation visible. Due to its functional nature, XSLT is particularly well-suited to software visualization, because an XSLT transformation can be represented and viewed as a static dataset. A subset of XSLT visualization (using a “trace-enabled” stylesheet to generate representations of transformation relationships) was used to empower non-programming staff to predict, understand, and manipulate content enrichment rules. We would like to generalize these case-specific techniques into a general tool for XSLT. There are challenges including scalability (memory usage), what to visualize and what not to, avoiding noise for the user, and whether to store annotations externally or within the result document.
Unleashing the Power of XSLT: Catalog Records in Batchc7002593
This document summarizes three case studies of using XSLT and AutoIT to automate cataloging workflows at different libraries. The first case study describes automating the cataloging of digitized monographs by extracting existing print records and inserting URLs. The second case study covers automating the cataloging of spoken word recordings by extracting data from a SQL database and matching it to existing analog records. The third case study involves using XSLT to "un-mulver" records for theses/dissertations that had print and microform on the same record into separate records.

The document provides an overview of web services, including their key features, architecture, and core technologies. It discusses how web services use standards like XML, SOAP, WSDL, and UDDI to allow software components to communicate over the internet in a manner that is self-contained, self-describing, and platform-independent. WSDL files describe web service operations and messages using an XML format, while SOAP is the messaging protocol used to make remote procedure calls between clients and services.
Web services and EAI allow for the exchange of data between different applications and systems. Web services use common protocols like HTTP, SOAP and XML to enable interoperability. To set up inbound and outbound web services in Siebel, integration objects are created to define the data structure and business service methods are defined as the service interface. The Siebel web service configuration is then completed by creating web service records in the application administration.
The document provides an overview of RESTful web services compared to SOAP web services. It discusses how REST is based on the architectural constraints of the web and uses HTTP methods to perform CRUD operations on resources. It also covers the core concepts of REST including resources, representations, and the REST constraints of being stateless, cacheable, etc. Examples are given of how RESTful services can use HTTP features like conditional GET requests and security mechanisms. Frameworks for building RESTful services and comparisons with SOAP are also summarized.
JAX-WS is the replacement and next generation to JAX-RPC and makes web services development much easier using annotations and much less configuration. JAX-WS is useful for people building webservices/SOA based infrastructure as JAX-WS makes the web service development much easier and is a big gain for developer productivity.
The session uses a web service for temperature conversion example to build both the client side and Server side artifacts. Also on the server side both Servlet based and EJB3.0 based web service development will be demonstrated. JAXB concepts will be used to demonstrate the examples.
The session uses Eclipse Ganymede and Jboss 5.0. However JAX-WS being the standard, the code will smoothly work on any JavaEE based compliant servers.
OAuth 2.0 allows third party applications to access resources without sharing credentials. It uses grant types like authorization code and implicit grant to obtain an access token. The access token is then used by the client to access resources from the resource server. DataPower supports OAuth 2.0 and provides customization options like additional grant types and extension points to customize the OAuth handshake process.
Web services use SOAP, WSDL, and UDDI. SOAP defines an envelope structure for messages. WSDL describes a service's operations, messages, and location. UDDI allows services to publish themselves so they can be discovered. The document discusses these technologies and how they enable interoperable machine-to-machine communication over the web.

Xml For Dummies Chapter 10 Building A Custom Xml Schema it-slideshares.blog...phanleson
This document provides steps for building a custom XML schema:
1. Understand the data that will be used in XML documents
2. Define the basic structural elements and how they relate to each other
3. Build content models that specify what type of content elements can contain
4. Create attribute declarations to provide additional context about data
5. Add datatype declarations to define what type of data each element and attribute will hold
The overall process involves analyzing the data, mapping out the document structure, and then defining validation rules in the schema.
An XML schema describes the structure and elements of an XML document. It defines elements, attributes, data types, properties like required/optional, and relationships between elements. XML schema is more powerful than older DTD schemas as it allows defining data types and namespaces. Schemas are written in XML syntax, making them easy to read, write and process using standard XML tools. This document provides examples of simple and complex element definitions in an XML schema.

XML schemas define the structure and format of XML documents. They validate that an XML document complies with the specified structure and elements. Key components of an XML schema include element definitions, attribute definitions, annotations, and type definitions. Schemas use XML syntax to declare elements, attributes, and other components, unlike DTD syntax.
This document provides an overview of XML, XML schema, parsing XML, and GladeXML. It defines XML and its components like elements and attributes. It describes XML schema and provides a simple example. It explains how to parse an XML document into a DOM object and access elements. It also gives an overview of how GladeXML can dynamically load user interfaces from XML descriptions.
XML is a markup language that allows for structured data storage and transport. It became popular as a data exchange format and was influenced by SGML. XML files must follow syntax rules like having a single root element, properly nested tags, and quoted attribute values. XML Schema (XSD) files can define the structure and validate XML content by specifying elements, attributes, and data types. XML can be processed using DOM which represents it as a tree structure or SAX which parses it sequentially through events.
XML is a markup language similar to HTML but designed for structured data rather than web pages. It uses tags to define elements and attributes, and can be validated using DTDs or XML schemas. XML documents can be transformed and queried using XSLT and XPath respectively. SAX is an event-based parser that reads XML sequentially while DOM loads the entire document into memory for random access.
This document provides an overview of XSLT (Extensible Stylesheet Language Transformations), XPath, and XQuery. XSLT is used to transform XML documents into other formats like HTML. It consists of templates, elements like for-each, and attributes like match. XPath allows navigation of XML documents using path expressions and axes. Common functions include substring and max. XQuery is similar to SQL for querying XML databases using FLWOR expressions, path expressions, and predicates to extract and filter data.

Seasoned XML programmers expect, and their productivity depends on the availability of languages and tools that allow usage of the patterns and practices native to the domain of XML programming. The object-oriented community, however, prefers XML data binding tools over dedicated XML languages because these tools automatically generate a statically-typed, vocabulary-specific object model from a given XML schema. Unfortunately, these tools often sidestep the expectations of seasoned XML programmers because of the difficulties in synthesizing abstractions of XML programming using purely object-oriented principles. This talk demonstrates how this prevailing gap can be significantly narrowed by a novel application of multi-paradigm programming capabilities of C++. In particular, how generic programming, meta-programming, generative programming, strategic programming, and operator overloading supported by C++ together enable native and typed XML programming.
The document discusses XSL (Extensible Stylesheet Language), which is used to style XML documents. Some key points:
- XSL is to XML what CSS is to HTML - it controls how XML documents are displayed.
- XSL has three main parts: XSLT for transforming XML, XPath for navigating XML, and XSL-FO for formatting XML.
- XSLT uses XSLT stylesheets to define transformation rules that are applied to XML documents to generate output like XML, HTML or text.
- Advantages of XSLT include being programming language independent and allowing output to be altered by modifying the XSL stylesheet without changing code.
The document discusses XML and related technologies:
1. XML is used to mark up data with user-defined tags and describes the structure of data. It is more flexible than HTML which uses predefined tags.
2. XML documents must follow basic rules like being well-formed with matching tags and properly nested elements.
3. XML can be validated using DTDs or XML Schema which define constraints and data types for elements.
The document provides an overview of XSLT (Extensible Stylesheet Language Transformations), which is an XML-based language used to transform XML documents. It discusses the basic XSLT processing model involving source XML documents, XSLT style sheets, and result documents. It also describes some important XSLT elements like <xsl:template>, <xsl:value-of>, <xsl:for-each>, <xsl:sort>, <xsl:if>, <xsl:choose>, <xsl:when> and <xsl:otherwise> that are used to transform and format the output XML document.

2. LIMITATION OF DTD
• DTD has limitation on the number of data type can be used.
• Can not recognize the namespace.
3. SCHEMAS
● A schema is an XML document that defines the content and structure of one or
more XML documents.
● The XML document that will be validated is called the instance document.
● Why Use an XML Schema?
● With XML Schema, your XML files can carry a description of its own
format.
5. XML SCHEMA V.S DTD
• XML Schemas are More Powerful than DTD:
• XML Schemas are written in XML.
• XML Schema supports a collection of built-in data types and allows
programmers to define their own data types.
• XML Schemas support data types.
• XML Schemas support namespaces.
6. STARTING A SCHEMA FILE
• A schema is always placed in a separate XML document that is referenced
by the instance document.
• A file written in XML Schema has the extension .xsd
• Since the Schema file is actually an XML file, it must start with an XML
declaration.
• The root element in any XML Schema document is the schema element ,
and it must declare a namespace for the XML Schema.
<?xml version=“1.0” encoding=“UTF=8”?>
<xs:schema xmlns:xs=”http://www.w3.org/2001/XMLSchema”>
schema content
</xs:schema>
9. SCHEMATYPES
XML Schema recognize two categories of element types that are:
1. A complex type element has one or more attributes, or is the parent to one or more child
elements.
2. A simple type element contains only character data and has no attributes.
13. SIMPLE TYPE ELEMENTS
• Use the following syntax to declare a simple type element in XML Schema:
<xs:element name=“name” type =“xs:type”/>
● Here, name is the name of the element in the instance document and type
is the datatype of the element.
● XML Schema tags must be qualified with the namespace prefix.
14.
15. DECLARINGANATTRIBUTE
• An attribute is always a simple type. The syntax to define an attribute is
<xs:attribute name="name" type="xs:type” />
• Where name is the name of the attribute and type is the data type.
• You can also define a default value and a fixed value for the attribute:
<xs:attribute name="name" type="xs:type” default=“default value”
fixed=“fixed value" />
• The default and fixed attributes are optional.
16. * notice that we did not specify which element the attribute belongs to
18. COMPLEX TYPE ELEMENTS
The basic structure for defining a complex type element with XML Schema is
<xs:element name="name">
<xs:complexType>
declarations
</xs:complexType>
</xs:element>
Where name is the name of the element and declarations are the declarations of the child elements or attributes
associated with the element.
19. COMPLEX TYPE ELEMENTS
Five complex type elements that usually appear in an instance document are
the following:
1–The element is an empty element and contains attributes only.
2–The element contains child elements only.
3–The element contains both child elements and attributes.
4–The element contains both child elements and text.
5–The element contains both attributes and text but no child element.
20. 1- ELEMENTS WITHATTRIBUTES ONLY
• The code to declare an element with attributes only:
<xs:element name="name">
<xs:complexType>
attributes
</xs:complexType>
</xs:element>
• Where attributes is the set of declarations that define the attributes associated with the
element. For example, the empty element:
<subject name="Cynthia Dibbs" age="62" />
• The code for this complex type element has the following structure:
<xs:element name="subject">
<xs:complexType>
<xs:attribute name="name" type="xs:string" />
<xs:attribute name="age" type="xs:string" />
</xs:complexType>
</xs:element>
21. SPECIFYING THE USE OFANATTRIBUTE
• An attribute may or may not be required with a particular element. To indicate whether an
attribute is required, you add the “use” attribute to the element declaration. The “use” attribute
has the following values:
• required: The attribute must always appear with the element
• optional: The use of the attribute is optional with the element
• prohibited: The attribute cannot be used with the element
• If you neglect to add the “use” attribute to an element declaration, the parser assumes that the
attribute is optional (meaning that “optional” is the default value for the “use” attribute).
• Example:
22. 2-ELEMENTS WITH CHILD ELEMENTS ONLY
To define child elements, use the code structure:
<xs:element name="name">
<xs:complexType>
<xs:compositor>
elements
</xs:compositor>
</xs:complexType>
</xs:element>
Where elements is the list of simple type element declarations for each child element, and compositor defines
how the child elements are organized.
23. USING COMPOSITORS
XML Schema supports the following compositors:
• sequence: defines a specific order for the child elements
• choice: allows any one of the child elements to appear in the instance
document
• all: allows any of the child elements to appear in any order in the
instance document; however, they must appear at least once.
27. 3- ELEMENTS WITH CHILD ELEMENTSANDATTRIBUTES
The code for a complex type element that contains both attributes and child elements is
<xs:element name="name">
<xs:complexType>
<xs:compositor>
Child Elements
</xs:compositor>
attributes
</xs:complexType>
</xs:element>
28. • The patient element contains two attributes (patID and onStudy) and seven child elements
(lastName, firstName, dateOfBirth, age, stage, comment, and performance.)
<xs:element name="patient">
<xs:complexType>
<xs:sequence>
<xs:element ref="lastName"/>
<xs:element ref="firstName"/>
<xs:element ref="dateOfBirth"/>
<xs:element ref="age"/>
<xs:element ref="stage"/>
<xs:element ref="comment" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="performance"/>
</xs:sequence>
<xs:attribute ref="patID" use="required"/>
<xs:attribute ref="onStudy" use="required"/>
</xs:complexType>
</xs:element>
3- ELEMENTS WITH CHILD ELEMENTSANDATTRIBUTES
30. 4- SPECIFYING MIXED CONTENT
• To declare an element that contains child elements and text, add the “mixed”
attribute and set it to “true”.
• Note that XML Schema allows content text to appear before, between, and after any
of the child elements.
31. For example, the XML content:
<Summary>
Patient <Name>Cynthia Davis</Name> was enrolled in
the <Study>Tamoxifen Study</Study> on 8/15/2003.
</Summary>
Can be declared in the schema file using the following complex type:
<xs:element name="Summary">
<xs:complexType mixed="true">
<xs:sequence>
<xs:element name="Name" type=“xs:string"/>
<xs:element name="Study" type=“xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
4- SPECIFYING MIXED CONTENT
32. 5- ELEMENTS WITH TEXTANDATTRIBUTES BUT NO CHILD ELEMENTS
If an element contains text and attributes (but no child elements), the structure of the
complex type element is slightly different.
<xs:element name="name">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:type">
attributes
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
33. For example, the empty element:
<performance scale="Karnofsky"> 0.81 </performance>
The code to associate the scale attribute with the performance element would
therefore be
<xs:element name="performance">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="scale"
type="xs:string" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
5- ELEMENTS WITH TEXTANDATTRIBUTES BUT NO CHILD
ELEMENTS
34. REFERENCINGAN ELEMENT ORATTRIBUTE
XML Schema allows for a great deal of flexibility in designing complex types. Rather
than nesting the attribute declaration within the element, you can create a reference to
it. The code to create a reference to an element or attribute declaration is
<xs:element ref="elemName" />
<xs:attribute ref="attName" />
Where elemName is the name used in an element declaration and attName is the name
used in an attribute declaration
37. SPECIFYING THE OCCURRENCE OFAN ITEM
• You can specify the occurrence of an element using the attributes minOccurs and maxOccurs.
• The minOccurs and maxOccurs can be any positive value
• The maxOccurs can have a value of “unbounded” for unlimited occurrences of the child
element
if minOccurs=”0” and maxOccurs is omitted ==> maxOccurs=”1” ==> the element is optional
if minOccurs=”x” and maxOccurs is omitted ==> maxOccurs=”x” (where x is any number greater
than 0)
if minOccurs and maxOccurs are both omitted ==> minOccurs=”1” and maxOccurs=”1”
*The default value for minOccurs and maxOccurs is “1”
“+” in DTDs is : minOccurs=“1” maxOccurs=“unbound”
“*” in DTDs is : minOccurs=“0” maxOccurs=“unbound”
“?” in DTDs is : minOccurs=“0” maxOccurs=“1”
39. SPECIFYING THE OCCURRENCE OFASEQUENCE
minOccurs and maxOccurs attributes can also be used with compositors to
repeat entire sequences of items
40. The Scope of an Element
Global Scope: Declarations that are placed as children of the root schema
element have a global scope, and can be referenced throughout the schema file.
Local Scope: Declarations that are nested within a complex type have a local
scope; they cannot be referenced elsewhere.
*Note:
• The attribute “use” for attributes is set locally.
• The attributes minOccurs and maxOccurs for elements are set locally.
• We declare the element or attribute globally, then specify the restrictions
locally.
41.
42. XML SCHEMA DATA TYPES
• XML Schema supports two general categories of data types:
• A built-in data type is part of the XML Schema language and is
available to all XML Schema authors.
• A user-derived data type is created by a schema author for
specific data values in an instance document.
43. XML SCHEMA DATA TYPES
• XML Schema divides its built-in data types into two classes:
• A primitive data type, also called a base type, is one of 19 fundamental
data types not defined in terms of other types.
• A derived data type is a collection of 25 data types that the XML
Schema developers created based on the 19 primitive types.
• Unlike DTDs, schemas use the same data types for both elements and
attributes.
53. APPLYINGASCHEMATOAN XMLDOCUMENT
● To attach a schema to the document, you must do the following:
–Declare a namespace for XML Schema in the instance document.
–Indicate the location of the schema file.
● To declare the XML Schema namespace in the instance document, you add the
following attribute to the document’s root element:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
● If there is no namespace for the contents of the instance document, add the
following attribute to the root element:
xsi:noNamespaceSchemaLocation="schemaFile.xsd"
