[xslt] python xslt messages

[Sam Brauer <sam webslingerZ com>]

I've been happily using the Python libxslt interface for a few weeks 
now, but I have noticed that sometimes there are error messsages written 
to stderr (for example, when a variable is referred to but was never 
declared, or when an xpath expression cannot be evaluated).  However no 
exceptions are thrown and I get a results back from 
parseStylesheetDoc() and applyStylesheet(), as if everything succeeded.

Is there some way via Python to access the warning/error messages (other 
than redirecting stderr) ?
