XML Pointer Language (or XPointer) defines a language for locating any element in a document. It is a special extension to a URL that allows it to access points deep within an XML document. XPointer connects to the end of a URL by the hash symbol (#), such as url#XPointer. XPointer is derived from XML Path Language (or XPath).
