XPATH Transform

Hi,
              Im trying to add XPATH transform in my digital signature and 
couldn't make it work using the addTransform() method in the transform class. 
The error im getting is posted below.

Original Exception was 
org.apache.xml.security.transforms.TransformationException: Cannot find ds:XPath 
in Transform
	at 
org.apache.xml.security.signature.Reference.getContentsAfterTransformation(Refer
ence.java:447)
	at 
org.apache.xml.security.signature.Reference.dereferenceURIandPerformTransforms(R
eference.java:600)
	... 5 more
Caused by: org.apache.xml.security.transforms.TransformationException: Cannot

	at 
org.apache.xml.security.transforms.Transform.performTransform(Transform.java:304
)
	at

Can you please let me know how can i add a XPATH tranform to address a part of 
the document that is signed?

Thanks
Hariprasath

Now i'm able to create <ds:XPath> element in my signature. But validation of the 
signature fails by saying that the digest value doesn't match any idea why it is 
happening?
