I wondered if there was some other possiblity. A solution like

$parser->warn_on_error(1);

would be much cleaner. After having a short look at LibXML.xs (at  
http://axkit.org/cgi-bin/viewcvs.cgi/XML-LibXML/LibXML.xs? 
rev=1.178.2.4&content-type=text/vnd.viewcvs-markup) from the  
XML::LibXML-CVS I see that the warning comes from the method

LibXML_report_error(SV * saved_error, int recover)

I wonder if it would be clean to change the signature to

LibXML_report_error(SV * saved_error, int recover, int warn_on_error)

and do the necessary replacements in the according calls of the  
function. Together with a simple change of LibXML.pm the should allow a  
construct like

$parser->warn_on_error(1);

If you want me to I can try to change LibXML.xs accordingly and send  
you a patch against the current CVS version.

Regards,

Benne
