6.4. Additional Information on XQuery

The official information on XQuery [10] is comprehensive and detailed, so much so in fact that it counts more than 170 printed pages. A more tutorial approach can be found in the XQuery book by Wamlsley [61] which gives good examples of use and tricks of the trade. Another excellent source of examples are given in the XQuery Cookbook [54]. It also gives examples of use of for the eXist database and how XQuery can be used with programming languages and environments.
