XML is a software- and hardware-independent tool for storing and transporting data.

XML files are plain text files just like HTML files. XML can easily be stored and generated by a standard web server.

An XML Schema describes the structure of an XML document, just like a DTD. An XML document with correct syntax is called "Well Formed". An XML document validated against an XML Schema is both "Well Formed" and "Valid".

An XML document with correct syntax is called "Well Formed". An XML document validated against a DTD is both "Well Formed" and "Valid".

Use our XML validator to syntax-check your XML.

XLink is used to create hyperlinks in XML documents.

XQuery is to XML what SQL is to databases. XQuery was designed to query XML data.

With XSLT you can transform an XML document into HTML.

XPath is a major element in the XSLT standard. XPath can be used to navigate through elements and attributes in an XML document.

The Document Object Model (DOM) defines a standard for accessing and manipulating documents:

All major browsers have a built-in XML parser to access and manipulate XML.

All modern browsers have a built-in XMLHttpRequest object to request data from a server.

Raw XML files can be viewed in all major browsers. Don't expect XML files to be displayed as HTML pages.

XML Namespaces provide a method to avoid element name conflicts.

XML elements can have attributes, just like HTML. Attributes are designed to contain data related to a specific element.

An XML document contains XML Elements.

The syntax rules of XML are very simple and logical. The rules are easy to learn, and easy to use.

XML documents form a tree structure that starts at "the root" and branches to "the leaves".

XML is used in many aspects of web development. XML is often used to separate data from presentation.

XML stands for eXtensible Markup Language. XML was designed to store and transport data. XML was designed to be both human- and machine-readable.
