HTML::Element Usage

smitz has asked for the wisdom of the Perl Monks concerning the following question:

I've been messing about with WWW:Robot, crawling my local intranet, and (planning on) storing some title and meta tags in a DB. Getting WWW::Robot to work was a piece of cake, but the the only way it returns the contents of a page is in an HTML::Element object.
The question is: what the hell do I do with it? I swear I've gone through all the docs, but its a bit over my head to be honest. I just want some simple tags from the object, any ideas?

Thanks,
SMiTZ

The HTML::Tree and HTML::Element documentation seems to point to a lot of interesting info, you seem to need something like this: `sub give_me_the_title { my $element = shift; # some HTML::Element my $title_element = $element->find_by_tag_name('title'); return $title_element->content_list(); }` [download] I haven't tried this and you really should take a longer look at the docs, it will be worth it in the long run - HTML parsers are complicated for a reason :-) If you really want to take a shot at making a quick hack, you could take a look at the HTML::Element->as_HTML() method.

I've been messing about with WWW:Robot, crawling my local intranet, and (planning on) storing some title and meta tags... Sounds exactly like one of my columns. -- Randal L. Schwartz, Perl hacker	[reply]
