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 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.
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.
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.
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 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.
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.
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.
The document discusses XML (eXtensible Markup Language) in 3 paragraphs:
1) It defines XML as a markup language used to provide extra information about a document by adding tags. HTML uses tags to tell browsers how to display documents, while XML tags give readers an idea of what the data means and separates presentation from data.
2) XML documents are used to transfer data, often over the internet. XML subsets are designed for particular applications like RSS for news feeds. Fields also have their own subsets registered with the W3C.
3) XML is popular because it allows complex structured data to be transmitted efficiently as a simple text stream but also processed as a rich object model in receiving applications.

The document discusses the history and standardization of HTML. It notes that HTML was originally created by Tim Berners-Lee at CERN in 1990 for scientific purposes. The development of graphical web browsers by Mosaic and Netscape in the early 1990s and the subsequent "Browser Wars" led to HTML being defined by each browser instead of standards. The World Wide Web Consortium was founded in 1994 to establish standards for HTML. The document outlines that HTML standardization involves both syntax, which defines valid characters and strings, and semantics, which describes the meaning of elements.
This document provides an overview of XML (eXtensible Markup Language) by comparing and contrasting it with HTML. It discusses how XML is used to mark up data for computers to process rather than for display like HTML. The document outlines the basic rules for well-formed XML, including the need for matching tags, proper nesting, and defined entities. It also covers XML extensions like namespaces, attributes, and how to define a valid XML vocabulary through DTDs or schemas.
XML stands for Extensible Markup Language and is used to mark up data so it can be processed by computers, whereas HTML is used to mark up text to be displayed for users. Both XML and HTML use elements enclosed in tags, attributes, and entities, but XML only describes content while HTML describes both structure and appearance. XML allows users to define their own tags, and is strictly structured, making it suitable for data processing by computers.
XML is a markup language used to carry data, not display it. It allows users to define their own tags for structuring data. XML separates data from presentation, allowing data to be stored and transported independently of formatting and style. This makes XML well suited for transporting data between incompatible systems.
The document provides an introduction to XML, explaining that it stands for Extensible Markup Language and is used to carry data rather than display it. XML tags are user-defined rather than predefined. It also discusses how XML separates data from HTML/display, and simplifies data transport between systems. Key aspects of XML like elements, attributes, and being well-formed are summarized.
XML is a markup language similar to HTML but designed to carry data rather than display it. XML allows users to define their own elements and tags to structure data. XML separates data from display, making it well-suited for transporting data between incompatible systems or updating dynamic web pages without changing HTML. CSS can be used to style XML documents for display.
- XML and HTML are both markup languages but have different purposes
- XML is used to store and transport data, HTML is used to display web pages
- XML focuses on describing data, HTML focuses on both structure and appearance
- XML allows users to define their own elements while HTML uses a fixed set of predefined tags
The document compares and contrasts HTML and XML. HTML is used to display web pages for humans, while XML is used to store and transport data for processing by computers. Some key differences are that HTML defines both structure and presentation, while XML defines only content. Also, HTML uses a fixed set of predefined tags, whereas XML allows users to define their own tags.
XML is a flexible data format that allows users to define their own tags to structure information in a way that makes it readable by both humans and machines. It allows sharing of data across different systems on the internet or intranets. XML uses tags to mark up content with semantic meaning, which facilitates parsing and allows the same information to be rendered in multiple formats.
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.
The document defines XML as a markup language for structured data similar to HTML but designed to carry data rather than display it. XML uses user-defined tags rather than predefined tags. It was introduced in 1998 by the W3C and is used widely on the web to transport and share data between applications. XML separates data from formatting and simplifies data sharing, transport, and platform changes by making data more available.
The document provides an overview of XML (Extensible Markup Language). It describes XML as a text-based markup language derived from SGML that uses tags to identify and organize data rather than display it like HTML. The document outlines key characteristics of XML including that it is extensible, carries data without presenting it, and is an open standard. It also provides examples of XML usage and describes the basic syntax and components of XML documents and elements.
The document discusses XML, XSLT, and XSL-FO, explaining that XML is used to store and exchange data, XSLT transforms XML documents, and XSL-FO formats XML data for output to different mediums like screens and paper. It also provides examples of using these technologies together and with Java or CSS to display XML content in different formats.
XML was designed to store and transport data in a human- and machine-readable format. It uses markup tags to describe and structure data. XML has several advantages over HTML, including being able to carry arbitrary data rather than just displaying it, and having customizable tags rather than predefined tags. XML documents form a tree structure with elements nested within each other. XML includes syntax rules for tags, elements, attributes, and comments. Namespaces help avoid conflicts between element names. Documents can be validated using DTDs or XML Schemas, which define the structure and legal elements. XML Schemas provide more power and capabilities than DTDs.
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. XML was designed to store and transport data. Key points about XML include:
- XML documents have a tree structure with a root element and branches to lower level elements
- XML has simple syntax rules and elements must be properly nested with matching open and close tags
- Elements can have attributes, text content, and child elements
- XML is self-descriptive and allows defining new elements for specific types of information
- XML documents can be validated against DTDs or XML Schemas to check syntax and structure
SGML is a standard for specifying markup languages. It describes how to define document structure separately from presentation. XML is a simplified version of SGML used to store and transport data. Key differences between XML and HTML include XML focusing on data rather than presentation, being case sensitive, requiring closing tags, and preserving whitespace.
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 allows users to define their own elements and tags. XML uses Unicode, has a clear syntax, and elements must be properly nested with closing tags. XML can be combined with stylesheets to format documents and is the foundation for web services technologies like SOAP, WSDL, and UDDI.
This document provides an overview of XML (eXtensible Markup Language). It discusses how XML is used to store structured data, compares XML to databases and HTML, and outlines the basic structure and syntax of XML documents. Key points covered include XML tags, elements, attributes, namespaces, parsing XML with PHP, and manipulating XML data using DOM and SimpleXML extensions.
XML is a markup language that is used to define and store data in a structured format. It allows data to be separated from its presentation and is extensible to add new tags. An XML document must have a root element and follow syntax rules to be well-formed. It can also be validated against a DTD or schema to check that the elements and structure match the definitions.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

2. HTML and XML, I
XML stands for eXtensible Markup Language
HTML is used to mark up XML is used to mark up
text so it can be displayed to data so it can be processed
users by computers
HTML describes both XML describes only
structure (e.g. <p>, <h2>, content, or “meaning”
<em>) and appearance (e.g.
<br>, <font>, <i>)
HTML uses a fixed, In XML, you make up
unchangeable set of tags your own tags
2
3. HTML and XML, II
HTML and XML look similar, because they are
both SGML languages (SGML = Standard
Generalized Markup Language)
Both HTML and XML use elements enclosed in tags
(e.g. <body>This is an element</body>)
Both use tag attributes (e.g.,
<font face="Verdana" size="+1" color="red">)
Both use entities (<, >, &, ", ')
More precisely,
HTML is defined in SGML
XML is a (very small) subset of SGML
3
4. HTML and XML, III
HTML is for humans
HTML describes web pages
You don’t want to see error messages about web pages you visit
Browsers ignore and/or correct as many HTML errors as they can,
so HTML is often sloppy
XML is for computers
XML describes data
The rules are strict and errors are not allowed
In this way, XML is like a programming language
Current versions of most browsers can display XML
However, browser support of XML tends to be inconsistent
4
5. XML-related technologies
DTD (Document Type Definition) and XML Schemas are used to
define legal XML tags and their attributes for particular purposes
CSS (Cascading Style Sheets) describe how to display HTML or
XML in a browser
XSLT (eXtensible Stylesheet Language Transformations) and
XPath are used to translate from one form of XML to another
DOM (Document Object Model), SAX (Simple API for XML,
and JAXP (Java API for XML Processing) are all APIs for XML
parsing
5
6. Example XML document
<?xml version="1.0"?>
<weatherReport>
<date>7/14/97</date>
<city>North Place</city>
<state>NX</state>
<country>USA</country>
High Temp: <high scale="F">103</high>
Low Temp: <low scale="F">70</low>
Morning: <morning>Partly cloudy, Hazy</morning>
Afternoon: <afternoon>Sunny & hot</afternoon>
Evening: <evening>Clear and Cooler</evening>
</weatherReport>
From: XML: A Primer, by Simon St. Laurent
6
7. Overall structure
An XML document may start with one or more
processing instructions (PIs) or directives:
<?xml version="1.0"?>
<?xml-stylesheet type="text/css" href="ss.css"?>
Following the directives, there must be exactly one tag,
called the root element, containing all the rest of the
XML:
<weatherReport>
...
</weatherReport>
7
8. XML building blocks
Aside from the directives, an XML document is
built from:
elements: high in <high scale="F">103</high>
tags, in pairs: <high scale="F">103</high>
attributes: <high scale="F">103</high>
entities: <afternoon>Sunny & hot</afternoon>
character data, which may be:
parsed (processed as XML)--this is the default
unparsed (all characters stand for themselves)
8
9. Elements and attributes
Attributes and elements are somewhat interchangeable
Example using just elements:
<name>
<first>David</first>
<last>Matuszek</last>
</name>
Example using attributes:
<name first="David" last="Matuszek"></name>
You will find that elements are easier to use in your programs--
this is a good reason to prefer them
Attributes often contain metadata, such as unique IDs
Generally speaking, browsers display only elements (values
enclosed by tags), not tags and attributes
9
10. Well-formed XML
Every element must have both a start tag and an end tag, e.g.
<name> ... </name>
But empty elements can be abbreviated: <break />.
XML tags are case sensitive
XML tags may not begin with the letters xml, in any
combination of cases
Elements must be properly nested, e.g. not <b><i>bold and
italic</b></i>
Every XML document must have one and only one root element
The values of attributes must be enclosed in single or double
quotes, e.g. <time unit="days">
Character data cannot contain < or &
10
11. Entities
Five special characters must be written as entities:
& for & (almost always necessary)
< for < (almost always necessary)
> for > (not usually necessary)
" for " (necessary inside double quotes)
' for ' (necessary inside single quotes)
These entities can be used even in places where they
are not absolutely required
These are the only predefined entities in XML
11
12. XML declaration
The XML declaration looks like this:
<?xml version="1.0" encoding="UTF-8"
standalone="yes"?>
The XML declaration is not required by browsers, but is required by
most XML processors (so include it!)
If present, the XML declaration must be first--not even whitespace
should precede it
Note that the brackets are <? and ?>
version="1.0" is required (this is the only version so far)
encoding can be "UTF-8" (ASCII) or "UTF-16" (Unicode), or
something else, or it can be omitted
standalone tells whether there is a separate DTD
12
13. Processing instructions
PIs (Processing Instructions) may occur anywhere in the XML
document (but usually first)
A PI is a command to the program processing the XML
document to handle it in a certain way
XML documents are typically processed by more than one
program
Programs that do not recognize a given PI should just ignore it
General format of a PI: <?target instructions?>
Example: <?xml-stylesheet type="text/css"
href="mySheet.css"?>
13
14. Comments
<!-- This is a comment in both HTML and XML -->
Comments can be put anywhere in an XML document
Comments are useful for:
Explaining the structure of an XML document
Commenting out parts of the XML during development and testing
Comments are not elements and do not have an end tag
The blanks after <!-- and before --> are optional
The character sequence -- cannot occur in the comment
The closing bracket must be -->
Comments are not displayed by browsers, but can be seen by
anyone who looks at the source code
14
15. CDATA
By default, all text inside an XML document is parsed
You can force text to be treated as unparsed character data by
enclosing it in <![CDATA[ ... ]]>
Any characters, even & and <, can occur inside a CDATA
Whitespace inside a CDATA is (usually) preserved
The only real restriction is that the character sequence ]]> cannot
occur inside a CDATA
CDATA is useful when your text has a lot of illegal characters
(for example, if your XML document contains some HTML text)
15
16. Names in XML
Names (as used for tags and attributes) must begin with
a letter or underscore, and can consist of:
Letters, both Roman (English) and foreign
Digits, both Roman and foreign
. (dot)
- (hyphen)
_ (underscore)
: (colon) should be used only for namespaces
Combining characters and extenders (not used in English)
16
17. Namespaces
Recall that DTDs are used to define the tags that can be
used in an XML document
An XML document may reference more than one DTD
Namespaces are a way to specify which DTD defines a
given tag
XML, like Java, uses qualified names
This helps to avoid collisions between names
Java: myObject.myVariable
XML: myDTD:myTag
Note that XML uses a colon (:) rather than a dot (.)
17
18. Namespaces and URIs
A namespace is defined as a unique string
To guarantee uniqueness, typically a URI (Uniform
Resource Indicator) is used, because the author “owns”
the domain
It doesn't have to be a “real” URI; it just has to be a
unique string
Example: http://www.matuszek.org/ns
There are two ways to use namespaces:
Declare a default namespace
Associate a prefix with a namespace, then use the prefix
in the XML to refer to the namespace
18
19. Namespace syntax
In any start tag you can use the reserved attribute name xmlns:
<book xmlns="http://www.matuszek.org/ns">
This namespace will be used as the default for all elements up to the
corresponding end tag
You can override it with a specific prefix
You can use almost this same form to declare a prefix:
<book xmlns:dave="http://www.matuszek.org/ns">
Use this prefix on every tag and attribute you want to use from this
namespace, including end tags--it is not a default prefix
<dave:chapter dave:number="1">To Begin</dave:chapter>
You can use the prefix in the start tag in which it is defined:
<dave:book xmlns:dave="http://www.matuszek.org/ns">
19
20. Review of XML rules
Start with <?xml version="1"?>
XML is case sensitive
You must have exactly one root element that encloses
all the rest of the XML
Every element must have a closing tag
Elements must be properly nested
Attribute values must be enclosed in double or single
quotation marks
There are only five predeclared entities
20
21. Another well-structured example
<novel>
<foreword>
<paragraph>This is the great American novel.
</paragraph>
</foreword>
<chapter number="1">
<paragraph>It was a dark and stormy night.
</paragraph>
<paragraph>Suddenly, a shot rang out!
</paragraph>
</chapter>
</novel>
21
22. XML as a tree
An XML document represents a hierarchy; a hierarchy is a tree
novel
foreword chapter
number="1"
paragraph paragraph paragraph
This is the great It was a dark Suddenly, a shot
American novel. and stormy night. rang out!
22
23. Valid XML
You can make up your own XML tags and attributes, but...
...any program that uses the XML must know what to expect!
A DTD (Document Type Definition) defines what tags are legal
and where they can occur in the XML
An XML document does not require a DTD
XML is well-structured if it follows the rules given earlier
In addition, XML is valid if it declares a DTD and conforms to
that DTD
A DTD can be included in the XML, but is typically a separate
document
Errors in XML documents will stop XML programs
Some alternatives to DTDs are XML Schemas and RELAX NG
23
24. Mixed content
An element may contain other elements, plain text, or both
An element containing only text:
<name>David Matuszek</name>
An element (<name>) containing only elements:
<name><first>David</first><last>Matuszek</last></name>
An element containing both:
<class>CIT597 <time>10:30-12:00 MW</time></class>
An element that contains both text and other elements is said to
have mixed content
Mixed content is legal, but bad
Mixed content makes it much harder to define valid XML
Mixed content is more complicated to use in a program
Mixed content adds no power to XML--it is never needed for anything
24
25. Example XML document, revised
<?xml version="1.0"?>
<weatherReport>
<date>7/14/97</date>
<place><city>North Place</city>
<state>NX</state>
<country>USA</country>
</place>
<temperatures><high scale="F">103</high>
<low scale="F">70</low>
</temperatures>
<forecast><time>Morning</time>
<predict>Partly cloudy, Hazy</predict>
</forecast>
<forecast><time>Afternoon</time>
<predict>Sunny & hot</predict>
</forecast>
<forecast><time>Evening</time>
<predict>Clear and Cooler</predict>
</weatherReport>
25
26. Viewing XML
XML is designed to be processed by computer
programs, not to be displayed to humans
Nevertheless, almost all current browsers can display
XML documents
They don’t all display it the same way
They may not display it at all if it has errors
For best results, update your browsers to the newest available
versions
Remember:
HTML is designed to be viewed,
XML is designed to be used
26
27. Extended document standards
You can define your own XML tag sets, but here are
some already available:
XHTML: HTML redefined in XML
XAML: eXtensible Application Markup Language
declarative language for Microsoft Silverlight and DirectX graphics
programming in Windows Vista or later
SOAP: Simple Object Access Protocol
defines the forms of messages and RPC’s (Remote Procedure Calls)
MathML: Mathematical Markup Language
describes math notation for integrating mathematical formulae into
HTML and other document types
SVG: Scalable Vector Graphics
describing two-dimensional vector graphics
27
28. Vocabulary
SGML: Standard Generalized Markup Language
XML : Extensible Markup Language
DTD: Document Type Definition
element: a start and end tag, along with their contents
attribute: a value given in the start tag of an element
entity: a representation of a particular character or string
PI: a Processing Instruction, to possibly be used by a
program that processes this XML
namespace: a unique string that references a DTD
well-formed XML: XML that follows the basic syntax rules
valid XML: well-formed XML that conforms to a DTD
