XPathXPath (XML Path Language) is an expression language for addressing portions of an XML document, or for computing values (strings, numbers, or Boolean values) based on the content of an XML document. The current version of the language is XPath 2.0.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. 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, XPath has rapidly been adopted by developers as a small query language, and subsets are used in other W3C specifications such as XML Schema and Xforms. DocFamily uses Xpath throughout the product. Xpath is mostly used in Document Template Design (DocDesign). |
