How to fetch text from span (class) using DomDocument

I'm new to domdocument. I'm trying to fetch plaintext or inner text from the span tag that belongs to a specific class

For example

<span class="test">hello world</span> // Need to retrieve hello world text

This is what I have done so far

$dom = new domDocument;
@ $dom->loadHTML($url);
$classname="test";
$finder = new DomXPath($dom);
$spaner = $finder->query("//span[contains(@class, '$classname')]"); // this returns  [length] => 2 which means two classes present with the name of "test", I need to fetch the first one
Solution

  • You are almost there. Assuming that your target <span> is the first in the $dom, try this:

    $spaner = $finder->query("//span[contains(@class, '$classname')][1]");
echo $spaner[0]->textContent

    ; Output should be:

    hello world
