count in xpath

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
