XPath 1.0 - Wikipedia, the free encyclopedia - Iceweasel. Overview[edit] The XPath language is based on a tree representation of the XML document, and provides the ability to navigate around the tree, selecting nodes by a variety of criteria.[2][3] In popular use (though not in the official specification), an XPath expression is often referred to simply as "an XPath".
Originally motivated by a desire to provide a common syntax and behavior model between XPointer and XSLT, subsets of the XPath query language are used in other W3C specifications such as XML Schema, XForms and the Internationalization Tag Set (ITS). XPath 2.0 Specification. XPath 2.0 - Wikipedia, the free encyclopedia - Iceweasel. XPath 2.0 is the current version of the XPath language defined by the World Wide Web Consortium, W3C. It became a recommendation on 23 January 2007.[1] XPath is used primarily for selecting parts of an XML document. For this purpose the XML document is modelled as a tree of nodes. XPath allows nodes to be selected by means of a hierarchic navigation path through the document tree. The language is significantly larger than its predecessor, XPath 1.0, and some of the basic concepts such as the data model and type system have changed.
