Hi All!
How can I tell HTML::TreeBuilder to parse invalid html files
gracefully ? Here is an example:
-----
#!/usr/bin/perl
use strict;
use warnings;
use HTML::TreeBuilder;
my $root = HTML::TreeBuilder->new_from_file(*DATA);
print +($root->look_down(_tag=>'div', class=>'text'))->as_text, $/;
__DATA__
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
</head>
<body>
<div class="body">
<div class="doc">
<p>some text
<div class="text">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
</head>
<p> some other text
</div>
</div>
</div>
</body>
</html>
--------
for some reason someone put head tag inside of div :)
all browsers handle such case correctly, but HTML::TreeBuilder
returns undefined text value if I use as_text method on
<div class="text">. Without inner head section all works
as expected.
Is there any way to tell HTML::TreeBuilder to handle
such situations ?
Thanks.
