XML Query

The mission of the XML Query working group is to provide flexible query facilities to extract data from real and virtual documents on the Web. The XML Query working group has published its Requirements Document and is hard at work defining its underlying data model.

The XML Query Language will be made up of two parts.  First is the XML Query Data Model. This data model for XML documents will serve as the foundation for the XML Query Algebra.  Queries will operate on single documents or fixed collections of documents. They can select whole documents or subtrees of documents that match conditions defined on document content and structure, and can construct new documents based on what is selected.

This work is currently underway.
