[xmlsec] Looking for programmer

[Chris Mcqueen]

Hoping to get help with this.  I am not C programmer, nor experienced 
with advanced XML.

I can take xml test file from vendor and sign/verify using my own test 
key/cert, but when I try to
verify XML signed by the vendor, I am getting the following error:

func=xmlSecXPathDataExecute:file=xpath.c:line=273:obj=unknown:subj=xmlXPtrEval:error=5:libxml2

If anyone can help or would like to do some contract work on my project, 
please let me know.

Thanks!
