I need to skip the `a` tags from within the list obtained by `$para->look_down("tag"=>'a');`, which have an id attribute equal to some value.
I am doing:
$str = '';
$str = $anchor->attr('id');
if ($str != 'a3') {
last;
}
This does not work when `id` attribute is not defined: it breaks out of the loop. How to do this?
以上就是How can I check if an id is present with Perl's HTML::TreeBuilder?的详细内容，更多请关注web前端其它相关文章！
