Parse DOM to multidimensional array PHP - php

Question

I want to Parse some DOM Content to a multidimensional array. Lets assume, I have this HTML Content
<for model="customer" id="0" processed="0">
<tag model="customer" value="name">name</tag>
<for model="accounts_receivable" processed="0">
<p>This is inside accounts_receivable</p>
</for>
</for>
I would like to parse this to:
array(
FOR => array (
ATTRIBUTES =>
SUBELEMENTS => array (
FOR => array (
ATTRIBUTES =>
SUBELEMENTS =>
)
)
)
)
I tried with parsing DOM via PHP with get ElementsByTagName, but its returning two for tags in the array.
The Key Point is, that the function should work with 2 layers or 20 layers.
Any good Idea?
Cheers,
Niklas

I wrote a function, doing this for "for" tag nodes. It ignores all other nodes, but parses recursively the complete DOM for all the for tag nodes.
$doc->loadHTML($this->template, LIBXML_NOWARNING | LIBXML_NOERROR);
$elements = $doc->getElementsByTagName('for');
$array = [];
if (!is_null($elements)) {
foreach ($elements as $element) {
if($element->getAttribute("processed") == false || $element->getAttribute("processed") != 1){
array_push($array, $this->parseDomChild($element));
}
}
}
function parseDomChild($element) {
$array = [];
if(isset($element->tagName) && $element->tagName == 'for') {
$array['nodeSelf'] = $element;
$element->setAttribute("processed", 1);
}
if($element->hasChildNodes()) {
$array['nodesChild'] = [];
foreach($element->childNodes as $node) {
array_push($array['nodesChild'], $this->parseDomChild($node));
}
}
return $array;
}
