The major capabilities of XQuery that distinguish it from other programming languages are its ability to:

Locate any content in an XML document
Create any XML document
Combine data to create new XML structures using FLWOR expressions

For a more extensive XQuery tutorial, refer to XQuery: A Guided Tour at: http://www.datadirect.com/developer/xquery/xquerybook/index.ssp

DataDirect XQuery, an implementation of XQuery, allows you to query both relational and XML sources and combine the data into one result.
