尝试使用Mojo :: DOM解析，但无法正确获取标签

Question

我正在使用$ ua从我的$ url =" http://finance.yahoo.com/quote/msft?p=mmsft中获取一些html;

我可以从URL中获取HTML内容。然后，我使用Mojo :: Dom进行子解析，这是正确的步骤，对吗？我想从Mojo $ url get（）HTML内容中进一步剥离HREF ...这就是我所拥有的：

my $ua = Mojo::UserAgent->new( max_redirects => 5, timeout => $timeout );
my $dom = Mojo::DOM->new;
my $content = $ua->get($url)->res->dom->at('div#quoteNewsStream-0-Stream')->content;
my $content2 = $content->$dom->find('a href#');

Answer 1

只需使用Mojo :: Useragent返回的Mojo :: DOM：

#!/usr/bin/env perl
use strict;
use warnings;
use v5.10;
use Mojo::UserAgent;
my $url = "http://finance.yahoo.com/quote/MSFT?p=MSFT";
my $dom = Mojo::UserAgent->new->get($url)->res->dom;
my $stream = $dom->at('div#quoteNewsStream-0-Stream');
for my $href ( $stream->find('a')->each ) {
    say $href->{href};
}
