Hi Raul,
thank you so much for your answer, I think the
problem comes more from my code than the xml sec
or the DOM parser.
But I did not verify the clue I have. I think
the problem comes from the fact that I create
the attribute xsi:type of the peerKeyIdentifier
element using setAttribute() instead of setAttributeNS()
here is the code that create <keyIdentifier xsi:type="roap:X509SPKIHash">
Element keyIdentifier = doc.createElement("keyIdentifier");
keyIdentifier.setAttribute("xsi:type", "roap:X509SPKIHash");
Element hash = doc.createElement("hash");
Do I have to create it using setAttributeNS()?
The parser is the latest xerces version.
Thks in advance
Regards
C�dric
