This section provides information about the implementation of XQuery in AquaLogic Service Bus. The World Wide Web (W3C) specification for XQuery defines a set of language features and functions. AquaLogic Service Bus uses the BEA AquaLogic Data Services Platform XQuery engine. The BEA XQuery engine fully supports language features with one exception (modules) and also supports a robust subset of functions and adds a number of implementation-specific functions and language keywords.
AquaLogic Service Bus supports a number of functions that are enhancements to the XQuery specification, which you can recognize by their extended function prefix fn-bea:
. For example, the full XQuery notation for an extended function is: fn-bea:function_name
.
For a list of the supported functions and a description of each function, see BEA XQuery Implementation in the XQuery Developer's Guide.
Caution: The following functions listed in BEA XQuery Implementation in the XQuery Developer's Guide are not supported by AquaLogic Service Bus:
Note: It is recommended that you do not use the following functions—they are better covered by other language features:
