The document presents an overview of XML and its usage and relationship to databases. It discusses how XML is a markup language used to transport, store, and share data. While XML is useful for small to medium amounts of data, it lacks features of relational databases and is less suitable for large data. The document also covers XML characteristics like being tag-based and user-defined, as well as how XML schema and validation are used.
XML is a markup language that is used to transport and store data. It uses tags and attributes to provide extra information about the data. XML documents are structured as trees, with a single root element and child elements nested within parent elements. The structure and elements of an XML document can be defined using a DTD or XML schema. Benefits of XML include being text-based, modular, and able to represent semantics along with data, while obstacles include verbosity and lack of intrinsic data types.
There are similarities between XML and databases in terms of storage, querying, and APIs. Storing XML in databases allows for indexing, efficient storage, and support for multiple users, transactions, security, and locking. XML documents can be stored in databases either as data-centric or document-centric documents. Data-centric XML is usually generated by systems and element order does not matter, while document-centric XML has unpredictable structure and element order is important. Native XML databases store XML as the fundamental unit, while XML-enabled databases convert XML to a database model, which can result in loss of information like element order. Web services use XML languages like SOAP and WSDL to enable interoperable machine-to-machine communication over
A comparison of a database table to an XML document. There is an overview of basic XML concepts suchs as attribute, element, entity, and tag. Data centric and document centric XML document are covered.
The document discusses the XML DOM (Document Object Model) which defines a standard for accessing and manipulating XML documents. It outlines the core DOM, XML DOM, and HTML DOM standards. The XML DOM provides an API that allows developers to navigate and modify an XML document tree. It has advantages like being language-independent and allowing traversal and modification of the XML tree, but uses more memory than SAX and is slower. The DOM organizes an XML document into a hierarchy of node types that can have child nodes.
XML is a markup language that structures, stores, and sends information. It allows users to define their own tags for structuring data. There are two major types of XML databases: XML-enabled databases that map XML to a traditional database, and native XML databases that use XML documents as the fundamental unit of storage. XML documents must follow rules like starting with an XML declaration, having a root element, and properly nesting elements. Common ways to query XML data include XPath and XQuery.
XML is a markup language used to provide extra context and structure to documents. It allows tags to be added that describe elements like names, emails, and dates. XML documents follow specific rules to be well-formed and can be validated using DTDs or schemas. XML is commonly used to transfer data between systems and applications use XML subsets tailored to their needs.
This document provides an introduction and overview of XML. It explains that XML stands for Extensible Markup Language and is used for data transportation and storage in a platform and language neutral way. XML plays an important role in data exchange on the web. The document discusses the history of XML and how it was developed as an improvement over SGML and HTML by allowing users to define their own tags to structure data for storage and interchange. It also provides details on the pros and cons of XML compared to other markup languages.

This document provides an introduction to XML, including:
- XML stands for eXtensible Markup Language and is used to store and transport data. It was designed to be self-descriptive.
- XML tags are defined by authors and are not pre-defined like HTML tags. XML separates data from presentation and can simplify data sharing, transport, and availability across platforms.
- XML documents form a tree structure and can be used complementarily with HTML to separate data storage from formatting and display.
This document discusses XML databases and effective search engines. It describes how XML is a self-describing format that can store data in a portable way. While XML lacks features of traditional databases like efficient storage and indexing, XML databases address these issues. The document outlines how XML databases can store, search, retrieve and display XML documents and compares them to relational databases. It also provides examples of technologies and modules that can be used to parse, insert, query and synchronize XML documents with databases.
eXtensible Markup Language (By Dr.Hatem Mohamed)MUFIX Community
XML is used to mark up data so it can be processed by computers, whereas HTML is used to mark up text for display to users. XML allows users to define their own tags, and elements in XML must have both a start and end tag. Well-formed XML requires proper nesting of elements and attributes enclosed in quotes.
XML presentation discusses XML (Extensible Markup Language). It describes XML as a text-based markup language derived from SGML that is extensible and carries data without presenting it. The document provides examples of XML documents and elements like articles, authors, titles, and text. It also discusses XML syntax rules, namespaces to avoid element name conflicts, and the importance of XML for data transfer, configuration files, schemas/templates, and more. Querying XML data with XPath and XQuery is also introduced.
This document provides an introduction to XML, including:
- XML stands for eXtensible Markup Language and allows users to define their own tags to provide structure and meaning to data.
- XML documents use elements with start and end tags to organize content in a hierarchical, tree-like structure. Elements can contain text or other nested elements.
- Attributes within start tags provide additional metadata about elements. Well-formed XML documents must follow syntax rules to be valid.
This document summarizes a seminar on XML and XML processors. It introduces XML and compares it to HTML. It describes the structure of an XML document including the prolog, data instance, and logical and physical structures. It also discusses XML processors and parsers, including DOM and SAX parsers. The document provides examples of DOM and SAX parsing approaches.
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 introduction to XML including its key characteristics and uses. XML allows for custom tags to store and transport data independently of how it is presented. It is an open standard developed by W3C. XML is commonly used to exchange information between organizations and systems, store and arrange customized data, and combine with style sheets to output desired formats. XML documents require a root element, closed tags, proper nesting, and quoted attribute values. The XML declaration specifies settings for parsing.
An XML processor takes an XML document and DTD file as input and processes them so that applications can access the information. There are two main API approaches for XML processors - SAX and DOM. SAX is an event-based approach where the processor signals events to the application as it recognizes syntactic structures. DOM builds a hierarchical tree of the document in memory that can then be randomly accessed by applications. SAX is faster but DOM allows random access and rearranging of the document.
This document provides an overview of XML, including what it is, its syntax and structure, common technologies used with XML, and advantages of using XML. XML is a markup language that uses tags to structure information to make it readable, unambiguous, and extensible. It allows data exchange between applications and includes elements, attributes, and comments. Related technologies include DTDs, schemas, and stylesheets.
XML (eXtensible Markup Language) is designed to transport and store data. It is important to know as it is easy to learn and allows data to be stored in a regular and consistent notation that can be processed faster and rearranged more easily. XML documents must have a root tag and follow syntax rules around tags, nesting, and attributes. XML is not a replacement for HTML as they have different goals around displaying versus describing information.
This document provides an introduction to XML (Extensible Markup Language). XML is derived from SGML and allows users to create structured data formats and share information. The document discusses XML documents, parsers, and document type definitions (DTDs). It also introduces XML schemas, namespaces, and common XML vocabularies used to describe different types of data like math expressions and vector graphics.
This document discusses XML use in libraries. It notes that XML allows for easy information sharing, has a strict yet human-readable syntax, and can create any needed structure. While XML requires an external application and is verbose, it supports schemas and namespaces. The document then summarizes several XML standards used in libraries, including EAD, OAI-PMH, NCIP, MARCXML and Dublin Core. It contrasts the DOM and SAX parsing methods and advises that XML is best for documents, messaging and data transport.
XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is designed to transport and store data with a focus on what data is. XML has several advantages over HTML such as being extensible, content-oriented, and providing a standard data infrastructure and data validation capabilities. XML documents form a tree structure with properly nested elements. XML uses tags to mark elements and attributes to provide additional information about elements.
XML is everywhere. Computers, Mobiles, Bank Systems, Internet, TVs, Microwaves, all use XML as an Information Wrapping and Information Xchange System. We will tell you all the basics in a simplest possible way.
XML is a markup language that allows users to define their own tags and structure for documents. It separates content from formatting and is readable, unambiguous, extensible, and platform independent. Key aspects of XML include elements, attributes, namespaces, comments, processing instructions, and CDATA sections. Documents must be well-formed with matching tags and can also be validated against a DTD to be valid.
XML and HTML have some key differences - XML provides user-definable tags while HTML has a defined set of tags for web display. XML is content-driven and end tags are essential, whereas HTML is format-driven and end tags are not always required. XML also requires quotes around attribute values and a slash in empty tags.
XML (eXtensible Markup Language) is used to describe data and its structure. It allows tags to be defined for different applications. XML documents can be transformed into other formats like HTML for display. XML uses tags enclosed in angle brackets that must be properly nested. Documents have a root tag and follow rules like being case sensitive. Data types and structures are defined in Document Type Definitions (DTDs) or schemas. XML documents have a tree structure that can be traversed to extract information. Extensible Stylesheet Language Transformations (XSLT) is used to transform one XML document into another format like HTML.
The document discusses XML, including its benefits over HTML and how XML documents are structured. It defines XML, describes how XML addresses limitations of HTML, and outlines the key components of an XML document, including elements, attributes, comments, and more. The goal is to introduce XML and explain how to build a basic but complete XML document.
XML stands for eXtensible Markup Language. It is used to store and transport structured data. XML allows users to define their own tags for marking up data with a tree structure, with one root element. Key features of XML include being extensible, using markup tags, and describing data in a human- and computer-friendly format. XML is commonly used for transporting data between systems and long-term storage of structured data.
The document discusses XML (eXtensible Markup Language) and XML schemas. It defines XML as a file format used to store hierarchical data marked with custom tags. XML files are human and machine-readable as they are plain text. The document then discusses how XML separates data from presentation, does not use predefined tags, and is extensible. It provides examples of XML files and schemas and the steps to validate an XML file against a schema using Python code.

XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is built on top of SGML and is an open standard developed by W3C. XML allows users to define their own tags to structure documents and is widely used for data exchange across different systems. Some key advantages of XML include being based on international standards, allowing user-defined tags, and having a hierarchical structure suitable for most document types.
XML (eXtensible Markup Language) is a meta markup language that allows defining custom markup languages. It became a W3C recommendation in 1998 and uses a tag-based syntax similar to HTML. XML allows defining tags to represent different types of text documents and data in a well-structured, machine-readable format. It is not a replacement for other technologies but can be converted to and used with many formats and languages.
Web based application of Live Scoreboard using XML.Uttam Kumar
The document discusses using XML to store live score data for a cricket scoreboard application to display on a web page. XML will be used to store the live score data separately from the HTML, allowing the data to be updated independently from the HTML layout. When the score is final, an XML parser will parse the XML data and insert/update it into a database for future queries. This allows frequently changing live data to be displayed quickly without needing to retrieve it from a database on each refresh.
This document discusses XML, its components like DTDs, and applications. It describes XML as a flexible markup language that allows arbitrary tags to encode semantic data. XML documents can be well-formed or validated against DTDs. Popular APIs like DOM and SAX allow programmatic access to XML documents. While XML is human-readable and widely adopted, its text-based nature uses more space and standardization remains a work in progress. The document also outlines evolving recommendations, industry XML databases, query languages, and how XML relates to systems research issues.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

5. JSON is a format/syntax
for storing and
exchanging data.
JSON is text, written with
JavaScript object
notation.
Breif Description
JSON is a lightweight
data-interchange format
JSON is "self-describing"
and easy to understand
JSON is language
independent *
6. Data is in name/value
pairs
Data is separated by
commas
Curly braces hold objects
Square brackets hold
arrays
Syntax
7. Data Types JSON support:
• string
• number
• object (JSON object)
• array
• boolean
Data-Type
• date
• time
• null
8. JSON objects are
surrounded by curly
braces { }.
JSON objects are written
in key/value pairs.
Keys must be strings, and
values must be a valid
JSON data type.
Keys and values are
separated by a colon.
DataTypes - Objects
Each key/value pair is
separated by a comma.
9. Arrays in JSON are almost
the same as arrays in
JavaScript.
In JSON, array values
must be of type string,
number, object, array,
boolean or null.
DataTypes - Arrays
10. When receiving data
from a web server, the
data is always a string.
Parse the data with
JSON.parse(), and the
data becomes a
JavaScript object.
Parser
14. XML is a markup
language much like
HTML
XML was designed to
store and transport data
HTML was designed to
display data elegently
Breif Description
XML Separates Data from
Presentation
XML is Often a
Complement to HTML
XML Separates Data from
HTML
15. XML documents are
formed as element trees
An XML tree starts at a
root element and
branches from the root
to child elements
All elements can have
sub elements (child
elements)
Syntax - Tree
16. XML may have conflict in
tags - They are defined
by developer
When using prefixes in
XML, a namespace for
the prefix must be
defined.
The namespace
declaration has the
following syntax.
xmlns:prefix="URI".
Syntax - Namespace
17. Primitive types XML
support:
• string
• decimal
• integer
• boolean
• date
• time
Data-Type
Supports many complex
data types including:
• charts
• graphs
• images
18. Before an XML document
can be accessed, it must
be loaded into an XML
DOM object.
All modern browsers
have a built-in XML
parser that can convert
text into an XML DOM
object.
Parser
20. XQuery is the language
for querying XML data
XQuery for XML is like
SQL for databases
XQuery is built on XPath
expressions
XQuery is supported by
all major databases
Data Access - XQuery

Use HTTP verbs of GET, POST,
PUT and DELETE for working
Plain Text, XML, HTML and
JSON. Rest APIs mainly has
JSON response
Editor's Notes
(XML Saparates Data from Presentation) XML does not carry any information about how to be displayed.
The same XML data can be used in many different presentation scenarios.
(XML is Complement toHTML) In many HTML applications, XML is used to store or transport data, while HTML is used to format and display the same data.
(XML Saperate Data from HTML) When displaying data in HTML, you should not have to edit the HTML file when the data changes.
With XML, the data can be stored in separate XML files.
With a few lines of JavaScript code, you can read an XML file and update the data content of any HTML page.
