Uisng xpath in basex1/13/2024 A number of implementations exist but are not as widely used as XPath 1.0. XPath 2.0 became a Recommendation on 23 January 2007, with a second edition published on 14 December 2010.XPath 1.0 became a Recommendation on 16 November 1999 and is widely implemented and used, either on its own (called via an API from languages such as Java, C#, Python or JavaScript), or embedded in languages such as XSLT, XProc, XML Schema or XForms.However, XPath 1.0 is still the version that is most widely available. XPath 1.0 was published in 1999, XPath 2.0 in 2007 (with a second edition in 2010), XPath 3.0 in 2014, and XPath 3.1 in 2017. There are several versions of XPath in use. XPath has been adopted by a number of XML processing libraries and tools, many of which also offer CSS Selectors, another W3C standard, as a simpler alternative to 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). In popular use (though not in the official specification), an XPath expression is often referred to simply as "an XPath". 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. Support for XPath exists in applications that support XML, such as web browsers, and many programming languages. It was defined by the World Wide Web Consortium (W3C) and can be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. XPath ( XML Path Language) is an expression language designed to support the query or transformation of XML documents.
