Hi All,

I am trying to use HTML::TreeBuilder to parse some HTML data I have retrieved from the web. Specifily, I would like to extract the sunrise/sunset data from the web page. Below is what I have tried. The attribute I am looking for is everything between the pre tags, However I am afraid I do not understand what is being displayed when I print the all_attr method :(

Can anyone shead some light on this?

Thanks

Ron Hill 


use strict;
use warnings;
use HTML::TreeBuilder;

my $data = do { local $/; <DATA> };

my $tree = HTML::TreeBuilder->new_from_content($data);

print $tree->all_attr();
