Your XPath expression have to select a single start node. The error
tells you that
the xpath expressiong you have used selected multiple or no nodes at
all. In your case
I would *guess* that you got no nodes because you did not specify namespaces
(and /dsig:Signature and /Signature xpath expression select different
nodes). Also
please note that for signatures, start node is expected to be
<dsig:Signature/> node.

BTW, there is a good XPath tutorial with a lot of examples:
You might want to look at it if you need to quickly find an Xpath expression
for your needs.
