fix bug in signature of getChildNodes
fix bug in signature of getChildNodes

a bug had getChildNodes signature taking 'tagName' but not doing anything
with it.  The result was that the first 'criteria' would be ignored.
No callers expected to pass tagName as second parameter, but expected the
correct signature.
