我有下面的代碼，我試圖從中提取'Washington square - USA'部分。 它位於div/p/strong內部，但div有一個類，如你所見。無法在xpath中獲取div元素中的子元素
是相關的代碼，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，我曾嘗試以下的方法來獲得回報所需的輸出內容
//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()
但沒有我想用這段代碼解析頁面
$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);
}
我沒有看到任何PHP代碼或你的pastebin參考中的XPATH。 – trincot
XPath工作。請顯示代碼在哪裏應用，結果如何，以及您的預期。 – trincot
使用'$ div-> textContent' [在本例中]（https://eval.in/748195）。 – trincot
