XPath Expressions
The XPath expressions used in the expected output panel are different from the usual webMethods path expressions. As mentioned in the Expected Output section, the indices start at 1 instead of the 0 based webMethods indices.
Test Suite uses JXPath for evaluating XPath expressions. For details on JXPath expressions, visit http://commons.apache.org/jxpath/. Special characters such as '@' and ':' in the name have special meaning in JXPath expressions hence, you should use special syntax variant to use these characters in variable name.
