XPath for BPEL processes
The XPath standard is well-suited for creating simple data-driven expressions. You can use the XPath standard in some areas of your BPEL processes. For example, you can use XPath to select parts of a BPEL variable or to iterate through the members of an array within a business object.
When you build an XPath expression in the BPEL process editor,
you can use the following types of functions:
- Standard functions that are defined by the XPath 1.0 specification
- Predefined extension functions that are included in IBM® Integration Designer
- Custom extension functions that your organization creates and defines
You can use the XPath Expression Builder to visually create an expression, or you can write them manually.
