PHP Accessing SimpleXMLElement Object array keys

Question

In the following SimpleXMLElement Object $results, I would like to remove the element with ID 13011146 from the TEST array. I'm not sure how to properly access the array key with value 1, so I'm using a counter $i, but that gives me an error Node no longer exists, pointing to the foreach line.

TL;DR: How do you unset $result->TEST[1] ?

SimpleXMLElement Object
(
    [TEST] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [ID] => 13011145
                        )

                )

            [1] => SimpleXMLElement Object
                (
                    [@attributes] => Array
                        (
                            [ID] => 13011146
                        )

                )
        )

)

PHP:

$i = 0;
foreach($results->TEST as $key => $value) {
    if( (string)$value['ID'] == 13011146 ) {
        unset($results->TEST[$i]);
    }
    $i++;
}

can you provide the XML for main SimpleXMLElement Object — maxjackie

foreach($results->TEST->children() as $key => $value) { 
    $attributes = $value->attributes();
    foreach($attributes as $a => $b) {
        if (( (string)$a == 'ID' ) && ( (string)$b == '13011146' )) {    
            unset($results->TEST[$key]);    
        }
    }
}

Sorry, misread your structure: Should be fixed by the call to children() - see edited version

Now we don't even enter in the first foreach loop :s If I remove children() then a match if found for $a and $b but again the value of $key is wrong.

a more elegant way; it gives you the same results without using $attributes[ '@attributes' ] :

$attributes = current($element->attributes());

For specific key/value pair, we can use like:

$attributes = current($value->attributes()->NAME);

Hope it helps !

Try this:

   $sxe = new SimpleXMLElement($xml);
   foreach ($sxe->children() as $child){
      foreach($child as $key=>$item){
         echo $key.': '.$item.'<br />';
      }
   }
