XPath to count the child nodes based on complex filter

Question

I have an XML in the following format:

Answer 1

@Bala-R (+1) is correctly evaluated using a compliant XSLT 1.0 processor (Saxon):

count(//ComRequest/root/component[count(compLine)>10])

or, either

count(/*/*/*[count(compLine)>10])

Otherwise something is going bad in your tests, your context (different from the one provided in the question) or your xpath evaluator.
