Addressing XML Parts Using XPath
xpath, the xml path language, is a language for addressing parts of an XML document. The language does not conform to the XML syntax. It can be used to formulate an expression that can be evaluated to some literal value, such as a number or string. It is also used to express an absolute or relative location path with respect to a current node, also called context node, in a conceptual tree structure of an XML document.
