推荐答案

如果您熟悉jQuery，则可能想查看

If you are familiar with jQuery you might want to check out pQuery, which makes this very easy:

## print every <h2> tag in page
use pQuery;

pQuery("http://google.com/search?q=pquery")
    ->find("h2")
    ->each(sub {
        my $i = shift;
        print $i + 1, ") ", pQuery($_)->text, "\n";
    });

还有 HTML :: DOM .

但是，无论您做什么，都不要为此使用正则表达式.

Whatever you do, though, don't use regular expressions for this.
