XPath reference - XPath | MDN
The following pages contain reference documentation for XPath.
Axes There are thirteen different axes in the XPath specification. An axis represents a relationship to the context node, and is used to locate nodes relative to that node on the tree.
XPath functions The following is an annotated list of core XPath functions and XSLT -specific additions to XPath, including a description, syntax, a list of arguments, result-type, source in the appropriate W3C Recommendation. For further information on using XPath/XSLT functions, please see the For Further Reading page.
