An href is attribute of an HTML element, hence $anchor->attr(q{href}) :-)

Have a look at the HTML::Element docs to see what the look_down, as_text, attr and replace_with_content methods do.

update

heh! Looking back at your original question I saw

I want to remove the href...

and I read that as removing the anchor tag from the HTML. :-)

Did you mean you wanted to get/extract the hrefs and store them in an array? If so you don't need the

$anchor->replace_with_content;

line. I'll get there in the end. :-)
