Read multiple tag attribute in an XML

Question

I want to read the XML and get the tag data <product zupid="fe36ddb561f0cd98f693722931fa2b83"> but I’m not getting it.

Part of XML:

<?xml version="1.0" encoding="UTF-8"?>

I’m using:

$url = "...";

$feed = simplexml_load_file($url);

foreach($feed->children() as $item){
   $IdProduto = trim($item->product('zupid');
   echo "$IdProduto<br>";
}

Answer 1

If you want to make a loop by all tags product, just do:

$feed = simplexml_load_file($url);
foreach($feed->children() as $item) {
    if($item->getName() == 'product') // somente se for product, eu imprimo o zupid
        echo $item['zupid']. "<br>";
}

---

Another option is to use DOMDocument along with DOMXPath to fetch the tags product and get the zupid of these:

$dom = new DOMDocument;
$dom->load($url);
$xpath = new DOMXPath($dom);
// procura as tags "product" dentro de "products"
foreach ($xpath->query("/products/product") as $p) {
    echo $p->getAttribute('zupid'). "<br>"; // pega o zupid
}

Answer 2

Suppose you have XML, an implementation can be:

<?php   
class simple_xml_extended extends SimpleXMLElement
{
    public    function    Attribute($name)
    {
        foreach($this->Attributes() as $key=>$val)
        {
            if($key == $name)
                return (string)$val;
        }
    }

}

$string = <<<XML
<?xml version='1.0'?>
<document>
 <product zupid="fe36ddb561f0cd98f693722931fa2b83"></product>
</document>
XML;

$xml = simplexml_load_string($string,"simple_xml_extended");

echo $xml->product->Attribute('zupid');

?>
