Re: [xml-dev] Java xml canonicalizer for comparing xml fragments

[Mitch Amiano <mitch.amiano@agilemarkup.com>]

There was a thread started by Dave Pawson discussing md5 checksums, 
which may have mentioned some libraries or tools. See 
http://www.stylusstudio.com/xmldev/200607/post00110.html for the start 
of the thread.
Libraries providing xml-signature functionality also provide 
canonicalization methods.
Ah, I may have replied to Dave directly. Here is a snippet I dug up from 
my outbox:


http://xml.apache.org/security/index.html seems to be what Sun refer to 
from their tutorial?

As you say, there *must* be some standard libs that do the C14N stuff.

The Apache libraries?
http://java.sun.com/webservices/docs/2.0/tutorial/doc/XMLDigitalSignatureAPI.html#wp268799
seems to be using Sun software with Apache libraries (security
libraries?)

http://xml.apache.org/security/dist/java-library/ is the Apache stuff,
but it's very sparse on documentation, other than the test stuff?
