XPath is the XML Path language (XML Path Language), which is a language used to determine the location of a part of an XML document. XPath is based on an XML tree structure that provides the ability to find nodes in a data structu
XPath uses path expressions to select nodes or node sets in XML documents. Nodes are selected by following the path or step (steps.XML instance document

The core idea of XPath design can be quickly introduced by xpath to locate the desired node. The main purpose is to describe the location of a node relative to another node. all qualified nodes can be obtained and become [location paths].
