FULL PRODUCT VERSION :
java version "1.5.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
org.w3c.dom.Node#getLocalName() returns null for element nodes. If I understand http://java.sun.com/j2se/1.5.0/docs/api/org/w3c/dom/Node.html#getLocalName() correctly, this is a bug.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See sample.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The element's name ('child' in the sample) should be returned.
ACTUAL -
null is returned.

REPRODUCIBILITY :
This bug can be reproduced always.
