domxpath - Extract li tags from second ul
domxpath, php
Solution
You can directly access them using XPath:
$xpath->query('//ul[2]/li');
Example:
$html = <<<EOF
<ul>
<li>Some text</li>
<li>Some text</li>
<li>Some text</li>
</ul>
<ul>
<li>Some more text</li>
<li>Some more text</li>
<li>Some more text</li>
</ul>
EOF;
$doc = new DOMDocument();
$doc->loadHTML($html);
$selector = new DOMXpath($doc);
// iterate through them...
foreach($selector->query('//ul[2]/li') as $li) {
echo $li->nodeValue . PHP_EOL;
}

Problem
I am trying to extract only the second ul's li tags from the following. Unfortunately, there are no classes or ids in the html to help ``` <ul> <li>Some text</li> <li>Some text</li> <li>Some text</li> </ul> <ul> <li>Some more text</li> <li>Some more text</li> <li>Some more text</li> </ul> ``` I have tried (a few things, actually): ``` $ul = $xpath->query('//ul')->item(1); $query = '/li'; $lis = $xpath->evaluate($query, $ul); ``` Thinking this will get me the second ul, and then I can extract from there. It does get me the second ul's html, but I'm obviously misunderstanding something with `->evaluate? because my li's are all the li's, not just from the second ul.
