Get data-filter attribute of all divs

Question

I have following html:

<div class="" data-filter="01">
    ...
</div>
<div class="" data-filter="02356">
    ....
</div>
<div class="" data-filter="02356">
    ...
</div>

How can I get the data-filter attribute of all those divs in PHP?

I've tried something like

$doc = new DOMDocument();
$doc->loadHTMLFile("items.html");

foreach ($doc->childNodes as $item){
    echo $item->getAttribute('data-filter');
}

but that throws Call to undefined method error .

Answer 1

Try this code:

$doc = DOMDocument::loadHTML($html);
$xpath = new DOMXPath($doc);
$query = "//div[@class='']";
$entries = $xpath->query($query);
foreach ($entries as $entry) {
    echo "Found: " . $entry->getAttribute("attrloc");
}

or use this php

change your code as below: need to cahnge method in foreach

$doc = new DOMDocument();
$doc->loadHTMLFile("items.html");

foreach ($doc->getElementsByTagName('div') as $item){    
  echo $item->getAttribute('data-filter');
}

Answer 3

The following code worked for me:

   $doc = new DOMDocument();
   $doc->loadHTMLFile("items.html");

   $elements = $doc->getElementsByTagName('div');

   if (!is_null($elements)) {
   foreach ($elements as $element) {
       echo $element->getAttribute('data-filter').'<br>';
   }

For more information regarding this, please see DOMDocument::loadHTMLFile in the PHP documentation .
