<DIV><SPAN class=157211516-22102004><FONT face=Arial size=2>I am new to libxml
and xmlsec, and having a hard time figuring out how to wedge in a protocol
handler to take care of resolving cid references. I looked at the links below,
and just am not sure how this would work for selectively handling cid, but
letting everything else (http, ftp, etc) pass through... I have looked through
the documentation, and traced the source... </FONT></SPAN></DIV>

<DIV><SPAN class=157211516-22102004><FONT face=Arial size=2>my real question is
this: By now, I assume that many of you have had to implement handling the
signing of attachments, I am just looking for a good starting point of how
you implemented this. I assume I have to somehow tap into the
xmlSecTransformCtxUriExecute function and do my own file reading... but can't
seem to figure out how..</FONT></SPAN></DIV>

<DIV><SPAN class=157211516-22102004>>> Well, probably the best option for
you would be option #2: use special URL protocol<BR>>> in URI attributes
like "cid:<attachment id>" and create custom protocol handlers<BR>>>
for "cid". Take a look at LibXML2 IO

do not forget to register your protocol handlers in both xmlsec and
