Hundreds of document formats using XML syntax have been developed, including RSS, Atom, SOAP, SVG, and XHTML.XML-based formats have become the default for many office-productivity tools, including Microsoft Office (Office Open XML), Open and Libre Office (Open Document), and Apple's i Work. Apple has an implementation of a registry based on XML.

Tutorial for RELAX NG using the compact syntax, not assuming prior knowledge of XML syntax. Also supports other schema languages including W3C XML Schema.
XML is an application profile or restricted form of SGML, the Standard Generalized Markup Language.
By construction, XML documents are conforming SGML documents." "XML is primarily intended to meet the requirements of large-scale Web content providers for industry-specific markup, vendor-neutral data exchange, media-independent publishing, one-on-one marketing, workflow management in collaborative authoring environments, and the processing of Web documents by intelligent clients.
Xml Class Testvalue set directly by instance of Testvalue set directly by instance of Testmagic __call called for method set Value on instance of Xml Classvalue set by instance of Xml Class and magic __callvalue set by instance of Xml Class and magic __call while using simple xml and get double or float int value from xml object for using math operations ( * - / ) some errors happens on the operation, this is because of simple xml returns everythings to objects.

Several introductory and tutorial articles on the Extensible Markup Language (XML) are referenced in the shorter XML Introduction document. "The Extensible Markup Language (XML) is the universal format for structured documents and data on the Web." -- W3C XML Web site, 2000-07-06.
The Extensible Markup Language (XML) is descriptively identified in the XML 1.0 W3C Recommendation as "an extremely simple dialect [or 'subset'] of SGML" the goal of which "is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML," for which reason "XML has been designed for ease of implementation, and for interoperability with both SGML and HTML." Note that the "HTML" referenced in the preceding sentence (bis) means HTML 4.0 and 3.2 which were in common use as of 10-February-1998, when the XML 1.0 specification was published as a W3C Recommendation.
Addition to QLeap's post: Simple XML will return a reference to an object containing the node value and you can't use references in session variables as there is no feasible way to restore a reference to another variable.
This won't work too:$val=$this-name;echo $array[$val]; // will cause a warning because of the wrong index type.
The next version of 'HTML' is expected to be reformulated as an XML application, so that it will be based upon XML rather than upon SGML.
