I can successfully filter the results of ID and child1 and child2. I want to be getting a parent and all of its children and grandchildren and greatgrandchild based on the value of greatgrandchild.</p> <p>Is this possible using xpath? </p> <p>I have edited the wording of the question and used the proper test.xml as I had errors in it the first time around. </p>
