| Subject: | XML::LibXML->new, recover flag, suppress warnings |
As reported today on the Perl-XML mailing list:
http://aspn.activestate.com/ASPN/Mail/Message/Perl-XML/3862042
In XML::LibXML, warnings are not suppressed when specifying the recover
or recover_silently flags as per the following excerpt from the manpage:
--------
recover
/parser, html, reader/
recover from errors; possible values are 0, 1, and 2
A true value turns on recovery mode which allows one to parse broken XML
or HTML data. The recovery mode allows the parser to return the
successfully parsed portion of the input document. This is useful for
almost well-formed documents, where for example a closing tag is missing
somewhere. Still, XML::LibXML will only parse until the first fatal
(non-recoverable) error occurs, reporting recoverable parsing errors as
warnings. To suppress even these warnings, use recover=>2.

Here's a test case to evidence the behaviour:
# use strict;
# use warnings;
# use utf8;
use XML::LibXML;
my $txt = <<'EOS';
<div>
<a href="/app/search?op=list&type=50">eins</a>
<!-- HTML parser error : htmlParseEntityRef: expecting ';' -->
</div>
EOS
my $prsr = XML::LibXML->new( # see perldoc XML::LibXML::Parser
recover => 2, # makes parser go on despite errors
# suppress_warnings => 1, # doesn't shut the warning off
# suppress_errors => 1, # not either
);
my $dom = $prsr->load_html( string => $txt );
print $dom->toString( 1 );
print "$_\n" for
XML::LibXML::LIBXML_DOTTED_VERSION, # 2.7.6 in my case
XML::LibXML::LIBXML_VERSION, # 20706
XML::LibXML::LIBXML_RUNTIME_VERSION; # 20707 yeah, I know ;-)
