PHP xpath contains class and does not contain class

问题

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>

Thanks!

This should do it:

<?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";
}

回答2:

Your XPath would be //div[contains(concat(' ', @class, ' '), ' result ') and not(contains(concat(' ', @class, ' '), ' grid '))]

回答3:

The XPATH syntax would be...

//div[not(contains(@class, 'grid'))]
