[xmlsec] Re: Problems signing...

[Aleksey Sanin]

Looks like the root element in xmlDocPtr (could be obtained
using  xmlDocGetRootElement()) is NULL. This can be if you
have mailformed XML document in the input. I think that
the simplest way to check this is to save XML template
just before signing.
