A DESCRIPTION OF THE PROBLEM :
When I try to use xml parser method such as "org.w3c.dom.Document.getElementsByTagName() ", it is retrieving "null" value for the tag. It is supposed to retrive the corresponding tag value.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please refer the source code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
getElementsByTagName() must retrieve the value for the tag name specified (from the xml file).
ACTUAL -
getElementsByTagName() retrieves "null" from the xml file

REPRODUCIBILITY :
This bug can be reproduced always.
