I am having trouble changing the value of an xml node in wp all imports for Wordpress Woocommerce. The xml feed lists Green, Amber, Red and Blue as it's stock levels. I need to change this to 12, 3, 0 and 0 for each value . I have looked at using simple xml but not sure this applies to this method. The function editor holds the custom php in a wordpress file much like the custom php file you would use in a child theme.
I have looked at this example in the link below but not sure how to apply it to what i am trying to acheive change value of xml node with simpleXML
This is the code i have got so far in the function editor
<?php
function ae_stock_change($x) {
if (StockLevel == "Green")
$x = 12;
elseif (StockLevel == "Amber")
$x = 3;
else $x = 0;
return $x;
?>
and this is the xml file example
<StockFile>
<MatrixID>1533</MatrixID>
