PHP xpath contains class and does not contain class

Question

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!

I haven't tried very much, only //div[contains(@class, 'result') and not contains(@class, 'grid')] and //div[contains(@class, 'result')][not contains(@class, 'grid')] but it was very apparent that my syntax was off right at the get go – Gitt

Answer 1

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";
}

This would also match anything with class = "*result" i.e. "someResult". So you gotta concat spaces to it. – Renewal

thanks for the comment crush, that is extremely helpful. as for the solution I'm certain this will work so I'll be giving credit once I'm at a computer and have verified the code. one last question: as a relatively new programmer, where should I be going for my solutions? I feel that asking questions on SO is lazy and that google provides messy resources. any advice? thanks again guys – Gitt

Following @Renewal 's comment, I think the correct way is //div[contains(concat(' ', normalize-space(@class), ' '), ' result ')], or //div[@class and contains(concat(' ', normalize-space(@class), ' '), ' result ')]. – Hillinck

Answer 2

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

Answer 3

The XPATH syntax would be...

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