Wp All import Hot to Add Child Element in XML that not have - wpallimport

Question

I had a problem with wp all import... I try to explain:
this is my XML
<Node>
<CodeID>1533</CodeID>
....
<Size>36|37|38</Size>
</Node>
the problem is that I need a child element of Size in this way
<Variations>
<Variation1>36</Variation1>
<Variation2>37</Variation2>
<Variation3>38</Variation3>
</Variations>
Is there a way or a functions to modify to have this xml and add all variations as a child element and not all in the same line?

<?php
$string = "<?xml version='1.0'?>
<Item>
<Node>
<CodeID>1533</CodeID>
<Size>36|37|38</Size>
</Node>
<Node>
<CodeID>L534</CodeID>
<Size>S|M|L</Size>
</Node>
</Item>";
$xml = simplexml_load_string($string);
$xml2 = simplexml_load_string($string);
//$xml = simplexml_load_file("./Items.xml", 'SimpleXMLElement', LIBXML_NOCDATA);
$i=0;
foreach ($xml as $item)
{
$variations_array = explode("|",$item->Size);
$j=0;
foreach ($variations_array as $variation)
{
$xml2->Node[$i]->Variations->Variation[$j] = $variation;
$j++;
}
$i++;
}
echo $xml2->asXML();
//$xml2->asXML("./Items2.xml");
/*
<?xml version="1.0"?>
<Item>
<Node>
