The XML Query Language

The XML Query Language (XQuery) specifies query processing to perform on XML resources. The result of an XQuery is an XML document containing the query results.

XQuery is a domain-specific language runtime accessed with an operator parameter referencing the XQuery script.

active:xquery+operator@{xquery-script}

The result of an XQuery program is a new resource which can be mapped to a URI address.

Reference

The xquery accessor is based on the Saxon library. There is also support for XQuery provided with the XMLDB module.
