XPath
XPath is a language for the navigation in XML documents. With the help of XPath expressions, all components of the tree can be exactly addressed and selected within the tree structure of a XML document. Since 2007, XPath is available in version 2.0 which is provided with numerous improvements and a significantly extended function library.
