Editing XML (section)

=== XML as data type ===
XML has appeared as a [[first-class data type]] in other languages. The [[ECMAScript for XML]] (E4X) extension to the [[ECMAScript]]/JavaScript language explicitly defines two specific objects (XML and XMLList) for JavaScript, which support XML document nodes and XML node lists as distinct objects and use a dot-notation specifying parent-child relationships.<ref>{{cite web|title=Processing XML with E4X|url=https://developer.mozilla.org/en/core_javascript_1.5_guide/processing_xml_with_e4x|work=Mozilla Developer Center|publisher=Mozilla Foundation|access-date=2010-07-27|archive-date=2011-05-01|archive-url=https://web.archive.org/web/20110501151224/https://developer.mozilla.org/en/core_javascript_1.5_guide/processing_xml_with_e4x|url-status=dead}}</ref> E4X is supported by the [[Mozilla]] 2.5+ browsers (though now deprecated) and Adobe [[Actionscript]] but has not been widely adopted. Similar notations are used in Microsoft's [[LINQ]] implementation for Microsoft .NET 3.5 and above, and in [[Scala (programming language)|Scala]] (which uses the Java VM). The open-source xmlsh application, which provides a Linux-like shell with special features for XML manipulation, similarly treats XML as a data type, using the <[ ]> notation.<ref>{{cite web|url=http://www.xmlsh.org/CoreSyntax|title=XML Shell: Core Syntax|website=Xmlsh.org|date=2010-05-13|access-date=22 August 2010}}</ref> The [[Resource Description Framework]] defines a data type <code>rdf:XMLLiteral</code> to hold wrapped, [[canonical XML]].<ref>{{cite web|editor1-first=G.|editor1-last=Klyne|editor2-first=J.
