試圖解析使用Mojo :: DOM，沒有得到標記正確

Question

我使用$ ua從我的$ url =「http://finance.yahoo.com/quote/MSFT?p=MSFT」中獲取一些HTML;

我可以從URL中獲取HTML內容。然後我使用Mojo :: DOM進行子分析，那是正確的一步，對吧？我想另外的條從魔$網址，以獲取（）html內容的A HREF ...這是我有：

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

只要使用由Mojo::UserAgent返回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}; 
} 

輸出：
