after several requests i made all parser functions croak() on errors in
XML::LibXML. This requires that all parser functions have to be evaled to
catch errors correctly. parsing an empty string is from the view of XML::LibXML
an error. that's why you get an server error there.
a solution would be to change any
$result = $parser->parse_xml_chunk($string)
to
eval { $result = $parser->parse_xml_chunk($string); };
or in case of appendWellBalancedChunk()
eval { $node->appendWellBalancedChunk($chunk); };
i don't think that i should catch the error in appendWellBalancedChunk()
itself, because then one will loose some informations on the application
level.
