Greetings fellow seminarians. My sympathies to those of you who, like me, are programming on Christmas Eve.

I am using HTML::TreeBuilder to parse HTML for the purposes of extracting information on some web pages, using HTML::Element to do this. When I do something like  my $d = $tree->look_down('class','date'); the hash I get back has a {_content} array with the values I want.

The docs describe keys beginning with underscore as "internal attributes," which I suppose means I'm not supposed to access the directly, but I can and do. For example my $date = $d->{_content}->[1]

But I'm wondering if there is a more proper construction for this. For example, in LWP::UserAgent you can get $response->status_line which I think accesses an internal attribute. In the date example my $date = $d->content[1] doesn't work. I've searched around and have not been able to find an answer.

In reply to HTML::Element accessing "internal attributes" the proper way by cormanaz
