Get all itemprop and itemprop depths

1.4k views Asked by Zoric At 23 November 2024 at 12:56

I have this code and it works more or less, the problem is some of them are empty and in wrong place in the array, and inside offers there's 3 other itemprops.

I dont want to hard code because I'm going to use it on multi websites.

function get_product_itemprop($url){
$url = file_get_contents($url);
$d = new DOMDocument();
$d->loadHTML($url);
$xpath = new DOMXPath($d);
$nodes = $xpath->query('//*[@itemprop]'); 

$new_data = array();
foreach ($nodes as $node) { 
    $new_data[$node->getAttribute("itemprop")] = trim(preg_replace('/\s+/', ' ',$node->nodeValue));
}
return $new_data;

}

Result of the function

    array(8) {
  ["breadcrumb"]=>
  string(38) "Home Atomizers & Coils Amor Mini coils"
  ["name"]=>
  string(15) "Amor Mini coils"
  ["sku"]=>
  string(5) "CO815"
  ["offers"]=>
  string(8) "$ 13.99"
  ["price"]=>
  string(0) ""
  ["priceCurrency"]=>
  string(0) ""
  ["availability"]=>
  string(0) ""
  ["url"]=>
  string(0) ""
  }

On http://search.google.com/structured-data/testing-tool I get all the itemprops and I want a similar structure they done but with an array:

You can iterate the attributes property:

foreach ($nodes as $node) {
    foreach ($node->attributes as $attr) {
        $new_data[$attr->nodeName] []= $attr->nodeValue;
    }
}

Example

$html = <<<'HTML'
<html>
    <body>
        <div itemprop="10" a="20" b="30"></div>
        <div itemprop="40" a="50" z="60"></div>
    </body>
</html>
HTML;

$d = new DOMDocument;
$d->loadHTML($html);
$xpath = new DOMXpath($d);
$nodes = $xpath->query('//*[@itemprop]');


$new_data = [];
foreach ($nodes as $node) {
    foreach ($node->attributes as $attr) {
        $new_data[$attr->nodeName] []= $attr->nodeValue;
    }
}
var_dump($new_data);

Output

array(4) {
  ["itemprop"]=>
  array(2) {
    [0]=>
    string(2) "10"
    [1]=>
    string(2) "40"
  }
  ["a"]=>
  array(2) {
    [0]=>
    string(2) "20"
    [1]=>
    string(2) "50"
  }
  ["b"]=>
  array(1) {
    [0]=>
    string(2) "30"
  }
  ["z"]=>
  array(1) {
    [0]=>
    string(2) "60"
  }
}

The sample code fetches all elements in the document having itemprop property. If you want to fetch all elements with properties, use @*, e.g. //*[@*].
