Describe the role Of XPath?

XPath is the effect of an effort to give a typical sentence structure, and semantics for usefulness shared between XSL Transformations [XSLT] and X-Pointer [X-Pointer]. The basic role of XPath is to address parts of an XML [XML] archive. In help of this basic role, it additionally gives basic facilities to control of strings, numbers, and booleans. XPath utilizes a minimal, non-XML language structure to encourage utilization of XPath inside URIs and XML attribute qualities. XPath works on the abstract, logical structure of an XML record, rather than its surface syntax. XPath gets its name from its utilization of path documentation as in URLs for exploring through the progressive structure of an XML archive.
