Functions Reference

The World Wide Web (W3C) specification for XQuery supports a discrete set of functions. BEA Liquid Data for WebLogic^TM supports a subset of those functions as built-in functions. The Liquid Data built-in functions are accessible in the Data View Builder from Builder Toolbar—>Toolbox tab—>Functions panel. (See also XQuery Functions in Starting the Builder and Touring the GUI.)

For more information on the functions described here, see also:

• W3C XQuery 1.0 and XPath 2.0 Functions and Operators specification.
• Appendix D, the Function and Operator Quick Reference in the XQuery 1.0 and XPath 2.0 Functions and Operators specification
• XML Schema Part 2: Datatypes

This section provides a complete reference of the W3C functions Liquid Data supports, as well as any extended functions Liquid Data supports. This functions reference is organized by category as follows:
