Hi Jamie,
it looks like this is my first mail in my life (I mean my previsou empty

We use Sablotron in mod_perl scripts with no problems (we use it in
little bit indirect way, so I'll try some simple test)

Can you send us sample perl script and data? (template and xml)?

foo doesn't have to point to anything, 'cos result buffer is allocated
by Sablotron.

"After cleanup" message never appears?
Few additional questions:
1. The same tamplate and data works with sabcmd?
2. Are there som other messages in Apache log (mainly messages produced
by Sablotron)
3. Sablotron needs to write into working directory. Has web user
permissions for it?
Have a nice day
