Overview of XML Technology

In this section, you will list some of the most important XML-related technologies. This is helpful for understanding and developing XML applications.

--------------------------------------------------------------------------------

XHTML-Extensible HTML (extensible HTML)
XHTML uses XML to redefine the syntax of HTML 4.01. XHTML 1.0 is the next version of HTML.

CSS-Cascading Style sheets (cascading style Sheets)
A CSS style sheet can add display information to an XML document.

XSL-Extensible Style single language (extensible Style Sheet Language)
XSL consists of three parts: XML document conversion (XML documents transformation, also known as XSLT), pattern matching syntax (a patterns matching syntax, also called XPath), format words objects (a formatting O Bject interpretation,xsl FO).

Xslt-xml Conversion Language (XML transformation)
XSLT is a much more powerful language than CSS. It can convert an XML document into a document in another format.

Xpath-xml Matching mode (XML pattern Matching)
XPath is a language used to identify parts of an XML document. This is a language designed for XSLT and XPointer.

Xlink-xml Link language (XML linking Language)
The link language (the XML linking Language, XLink) allows you to establish a link between different XML resources.

Xpointer-xml pointer language (XML pointer Language)
The XML pointer language (the XML pointer Language, XPointer) identifies the internal structure of an XML document, such as elements, attributes, content, and so on.

DTD-Document type definition (DOC type definition)
DTDs are primarily used to define the elements that are used to write XML documents.

Namespaces-namespaces
XML namespaces provide a way to relate elements, attributes, names, and URL addresses to each other.

Xsd-xml schema (XML schema)
Schemas can be replaced with DTDs and are more powerful. Schemas are written in XML format and support namespaces and data types.

XDR-Data simplification (XML reduced)
XDR is a simplified version of an XML Schema (XML Schema). The Ie5.0+ browser supports XDR.

DOM-Document Object model
The DOM defines the interfaces, properties, and methods of an XML document.

Xql-xml Query Language (XML query Language)
XQL provides a convenient query language for storing data in an XML document.

Sax-xml Simple API (plain API for XML)
SAX is another programming interface for reading and manipulating XML documents. (similar to DOM)

About the Consortium
The Internet organization, the World Wide Web Consortium, was founded in 1994. Mainly through the development of various WWW protocols to lead the Web. For example, HTML, CSS, and XML are made by the consortium.

The most important task of the consortium is to develop network specifications, or to describe some of the technologies that construct the Web.
