抓取列表以使用Goutte和PHP获取href的问题

Question

我试图刮掉以下内容,我基本上想要文本和链接,我正在使用Goutte和PHP.我可以使用以下代码获得文本,但我无法获得href值.任何帮助都会很棒.

$crawler->filter('#most-popular > div > ol > li > a')->each(function ($node) {
    var_dump($node->getAttribute('href'));
});


<li class="first-child ol1">
  <a href="http://www.bbc.co.uk/news/uk-england-south-yorkshire-31895703" class="story">
    <span class="livestats-icon livestats-1">1: </span>MP claims £17 poppy wreath expenses</a>
</li>

Answer 1

getAttribute()被实现为attr()所述内Crawler类.

$crawler->filter('#most-popular > div.panel.open > ol > li.first-child.ol1 > a')->each(function ($node) {
    var_dump($node->attr('href'));
});

Answer 2

波纹管代码将解决此问题.

$crawler->filter('#most-popular > div.panel.open > ol > li.first-child.ol1 > a')->each(function ($node) {
    $href = $node->extract(array('href'));
    var_dump($href[0]);
});
