[xmlsec] XPointer reference problem

[Asbj�rn Oskal]

Hi!   I'm having some trouble signing using an xpointer reference.   The XML document I'm trying to sign looks like this:   <?xml version="1.0" encoding="UTF-8"?> <Letter>     Hello, World!        <Info Id="SomeData">     <!-- Commentary -->     <Data1> Some data </Data1>     <Data2> More data </Data2>     </Info> </Letter>   I do like this in my code. (from signing example 3):   referenceNode = xmlSecSignedInfoAddReference(signedInfoNode,      (const unsigned char *) "my-reference",      (const unsigned char *) "#xpointer(id('SomeData'))",                     NULL);     I debugged the signing process and it ends up in xmlSecTransformStateParseUri (transforms.c) where   xmlXPtrEval(BAD_CAST (xptr + 1), ctxt);   fails.   The xptr contains #xpointer(id('SomeData')).     Does this mean that the xmlXPtrEval cannot find the element <Info Id="SomeData"> ?   Has anyone got a clue to what I am doing wrong here?   :)
