我有下面的代码，我试图从中提取'Washington square - USA'部分。 它位于div/p/strong内部，但div有一个类，如你所见。无法在xpath中获取div元素中的子元素
是相关的代码，或者你可以看到entire code in pastebin
<div class="content clearfix">
<p><strong>Washington square - USA<br>
</strong></p>
<p><strong>2 studios for rent – env. 54m2</strong></p>
<p><strong>near public transport</strong></p>
<p>Studios comprise</p>
<ul>
<li>A kitchen</li>
<li>A bedroom</li>
<li>Tolilet with bathtab</li>
</ul>
<p>Visitation date (not yet known)</p>
<p>To rent from 1st april</p>
<p>(Current owner : Ben)</p>
<p><strong>For more details visit: http://example.com<br>
</strong></p>
<p><strong> </strong></p>
</div>
所以，我曾尝试以下的方法来获得回报所需的输出内容
//div[contains(@class, "content")]/p/strong
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p[1]/strong
//string(div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong)
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong/text()
但没有我想用这段代码解析页面
$document = new \DOMDocument();
$document->loadHTMLFile($htmlUrl);
$xpath = new \DOMXPath($document);
foreach ($xpath->evaluate('//div[contains(@class, "content")]//p[1]') as $div) {
# Also tried with these
//div[contains(@class, "content")]/p/strong
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p[1]/strong
//string(div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong)
//div[contains(@class, "content") and contains(@class, 'clearfix')]/p/strong/text()
var_dump($div);
}
我没有看到任何PHP代码或你的pastebin参考中的XPATH。 – trincot
XPath工作。请显示代码在哪里应用，结果如何，以及您的预期。 – trincot
使用'$ div-> textContent' [在本例中]（https://eval.in/748195）。 – trincot
