Creating XPath Expressions

This section describes how to create XML Path (XPath) expressions in LiveCycle Workbench ES. XPath expressions are used in processes to identify data items in the process data model, such as data stored in process variables. For example, the XPath expression /process_data/@id identifies the id node in the process data model.

When this expression is evaluated at run time, it returns the data that the id node represents, which is the identification number for the process instance.

Expressions can include paths to data nodes, as well as functions and operators that act on the data:

In processes, you can use XPath expressions to specify values for operation properties, values in configuration dialog boxes for events, and values in routing conditions. You can use XPath Builder to create expressions, or you can enter them manually.

Please note that org.apache.xalan.xslt.XSLTProcessor is actually "not found" in the turnkey JBoss that comes with LiveCycle. You can use org.apache.xalan.processor.TransformerFactoryImpl instead.

Thank you for this comment. I believe it is meant to be associated with the Creating Processes > Service reference > XSLT Transformation > Transform topic.

You are correct that the example value of org.apache.xalan.xslt.XSLTProcessor is incorrect for the Factory Options property of the Transform operation. The value should be org.apache.xalan.processor.TransformerFactoryImpl, as you indicated.

This is the link for the Transform topic, to which I've also added a comment:
