XQuery Reference
This section provides XQuery reference information for queries (written in the XQuery language) that you build with the mapper provided for transformations in business processes and web services. It provides descriptions of the XQuery operator and functions available from the mapper. In addition, it provides reference information on the occurrence indicators, namespace prefixes, and XML Schema data types used in the XQuery language.
To learn more about creating data transformations in business processes, see Guide to Data Transformation.
For more information on transformations in web services (where they are also called XQuery maps), see Transforming XML Messages with XQuery Maps.
Note: The queries generated using WebLogic Workshop for transformations in business and web services conform to the W3C Working Draft 16 August 2002 of XQuery 1.0. For more information about this specification, see the following URL available from the W3C Web site:
http://www.w3.org/TR/2002/WD-xquery-20020816/
The queries generated using Liquid Data for WebLogic conform to the W3C Working Draft 30 December 2001 of XQuery 1.0. For more information about this specification, see the following URL available from the W3C Web site:
http://www.w3.org/TR/2001/WD-xquery-20011220/
For Liquid Data XQuery Reference information, see the Liquid Data XQuery Reference Guide.
In addition to the XQuery functions and operators available in the mapper functionality, a larger set functions and operators is provided. You can manually add invocations to these functions and operators to queries in the Source View of the mapper functionality. For a list of these additional functions and operators, see the XQuery 1.0 and XPath 2.0 Functions and Operators - W3C Working Draft 16 August 2002 available from the W3C Web site at the following URL:
