XQuery

(XML 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.

In particular, the idea of mining association rules [1] to provide summarized representations of XML documents has been investigated in many proposals either by using languages (e.g., XQuery [2]) and techniques developed in the XML context, or by implementing graph-or-tree-based algorithms.
Designed to meet the data transformation and aggregation needs of developers, the DataDirect Data Integration Suite contains the latest product releases of DataDirect XQuery [R], DataDirect XML Converters[R] (Java [TM] and NET) and Stylus Studio[R] in one simple, highly flexible and robust installation.
Many SQL-based DBMSs now support storing of XML data, as well as querying XML data directly using a query language such as XQuery.
XML programmers and database users will find Priscilla Walmsley's XQUERY (0596006349, $49.99) a specific, valuable reference which is based on the Xquery 1.0 standards and which offers a basic tutorial on specifications and programming with the query language base.
Because XPath complexity influences the complexity of query expressions (XQuery (25)) required to target document sections and data elements, these results suggest that searching XML document collections would be simpler and less prone to error with CLP-ML than CDA markup.
