Dear all,

I have a third-party program which calls a stylesheet and uses the
returned output. The application uses the MSXML engine to do the
transformations. Users are able to create their own stylesheets.

Documentation of the XSLT format is sketchy at best, so trying to
create my own stylesheet is rather difficult. I made one which does
what I want for now but I want to look a bit deeper into it.

My questions are:

1)Does MSXML allow somehow to debug the XSLT by stepping into it
whenever it is called from the external program? Like, could I use
Visual Studio 2008, put in some breakpoints, launch the app, and get
it to break into Visual Studio 2008 on the stylesheet calls?

2)As the third-party program does not output xsl:message contents,
does MSXML output it to somewhere by default? A simple file somewhere
on my drive? Or maybe an eventlog? Or could I instruct it to do so for
a while?

3)Is there a way to see what the XML is that is send together with the
XSLT to the transformation engine?

TIA,

Yves
