Hello!
I really feel that I have exhausted every approach that I can think of to solve this
problem. I need to sign a document using a Reference URI but it fails every time. I
can only sign the document using a Reference Id. I hope someone can help. Below is
what I think are the essentials of my document (the whole document is much larger).
The call to xmlSecDSigCtxSign will fail. It fails in xpath.c in the function
xmlSecXPathDataExecute with the message
"expr=xpointer(id('Id-058b5a86-a1dd-4188-9920-8315c3f84eae'))".
I know what has been said about using wsu:Id but I don't have any choice. That's why I
added the DOCTYPE. Please someone, make my day :-) This is driving me nuts.
It it matters any I'm running this on a Windows XP OS using the latest binaries of all
necessary libraries.
Thanks all,
Erik F. Andersen
