PHP xpath包含类，但不包含类 [英] PHP xpath contains class and does not contain class

问题描述

标题进行了总结.我正在尝试在HTML文件中查询所有包含类result且不包含类grid的div标签.

The title sums it up. I'm trying to query an HTML file for all div tags that contain the class result and does not contain the class grid.

<div class="result grid">skip this div</div>
<div class="result">grab this one</div>

谢谢！

推荐答案

这应该做到:

<?php
$doc = new DOMDocument();
$doc->loadHTMLFile('test.html');

$xpath = new DOMXPath($doc);
$nodeList = $xpath->query(
    "//div[contains(@class, 'result') and not(contains(@class, 'grid'))]");

foreach ($nodeList as $node) {
  echo $node->nodeName . "\n";
}
