QUERY Language) A language for querying XML documents from the W3C. Compatible with related W3C standards (W3C XML Schema, XSLT, etc.), XQuery was derived from the XPath language and uses the same syntax for path expressions. Based on the XQuery data model, XQuery processes the query by parsing the XML document, the schema and the query into hierarchical node trees. It also generates an output schema with the query results. See
XSL and
DOM.
