[Mono-list] XSLT debugging ...

[Michael Meeks]

Hi guys,

	So - I have this (horribly complicated) zip + XSLT + C# application
with this much XSLT goodness:

resources> find -name '*.x??' | xargs cat  | wc -l
54915

	And of course, since there is -at-least- 1 bug somewhere in it,
everything blows up, and I get these beautiful exception stacks (one of
which I append for your pleasure) :-) [ of course the bug may be in the
template processor too, hard to say, allegedly it works on Win32 ;-) ].

	So - my question is - how do people debug 55k lines of XSLT ? :-) and -
more to the point, when something fails how do we get a decent 'stack
trace' from the XSLT code ? [ I tried adding some 'Call Template'
tracing debug - as you see, but quickly get swamped ].

	What I would -love- would be a simple piece of code that just dumped
the file/line information to the console (or Debug. or whatever) and
re-threw the exception, perhaps in 'XslTemplate.Evaluate' or something
(?) [ we get a good number of frames of that ].

	Is that an easy thing to hack up ? I started reading the XSLT processor
while tired last night, but to no avail :-)

	The code is at: https://svn.sf.net/svnroot/odf-converter/trunk but
while it's appreciated, I'd prefer to improve Mono's diagnostics than
the XSLT itself.

	Thanks,

		Michael.
