XQuery, XSLT 2 and XPath 2 Are W3C Recommendations

The World Wide Web Consortium has published eight new standards in the XML family for data mining, document transformation, and enterprise computing from Web services to databases. "Over 1,000 comments from developers helped ensure a resilient and implementable set of database technologies," said Jim Melton (Oracle). XSLT transforms documents into different markup or formats. XML Query can perform searches, queries and joins over collections of documents. Using XPath expressions, XSLT 2 and XQuery can operate on XML documents, XML databases, relational databases, search engines and object repositories.
