Build a simple expression when
you must reference the data represented by a node in the process
data tree. Simple expressions include a path to the data node.
You can also build expressions with nodes of XML variables that
conform to an XSD that references XSD files.
In XPath expressions, the @ symbol precedes
simple variable types, and is not present in the complex variable
types. The following expression references the value stored in the string variable
The following expression references the value stored in the xml variable
To build an expression that uses process variables:
Navigate the process data tree to locate the item that you

Choose either of these ways to add the item to the expression:
Note: To build expressions
that contain nodes of XML variables that conform to an XSD that
references XSD files, drill down to the nodes as desired in the
For example, if you select the status
and click Insert Selection, the expression that identifies that
node appears in the expression work area.
A. Selected node B. Click to insert C. Inserted expression
