The idea is to use xpath count function
1. count(//help)
This is NO xml namespace. This is OK by the method useInputSource(). The count is 1 as expected.
2. count(//mylaws:help)
This is with xml namespace. This is NOT OK by the method useDom() and selectCount(Object inputSource,
String expression) { // This is for useDom()
The count is 0.
I tested with XPath-View and it return 1 as expected.
What/where/why is the issue in the method selectCount(Object inputSource, String expression) { // This is for useDom()
