PHP xpath contains class and does not contain class
提问by Rob
The title sums it up. I'm trying to query an HTML file for all div tags that contain the class resultand does not contain the class grid.
标题总结了它。我正在尝试为包含 classresult和不包含 class 的所有 div 标签查询 HTML 文件grid。
<div class="result grid">skip this div</div>
<div class="result">grab this one</div>
Thanks!
谢谢！

This should do it:
这应该这样做：
<?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";
}

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

The XPATH syntax would be...
XPATH 语法将是...
//div[not(contains(@class, 'grid'))]
