SimpleXML: how to get node value with a condition on parse rule? - php

Question

I have a XML file which was generated by an external entity that I want to parse using SimpleXML. My problem is that in the mapping given by the client I have some conditions in it to get the info I want.
For example, the mapping for the client code is something like this: E1ADRM1\PARTNER_Q=OSO\E1ADRE1\EXTEND_D which means that the code for the client is the value of the EXTEND_D tag, which is nested in one of the many PARTNER_Q tags. The one that has the OSO value.
I am starting today to explore SimpleXML, so I have no idea how to get this info.
For what I've read so far, it is pretty simple to get the info of a node, accessing it's properties. If I a single PARTNER_Q and no condition, my $clientCode would be $xml->E1ADRM1->PARTNER_Q->E1ADRE1->EXTEND_D (right?)
Any hint on how can I get the info having that PARTNER_Q=OSO condition in mind?

For future reference, I'll leave here the code with how I've solved this.
I've Based my code on this well written answer that I found.
$root = $xml->IDOC;
$shippingPoints = array();
// Go through the list of OTs
foreach($root->E1EDL20 as $ot) {
// Instanciate empty OT
$otInfo = emptyOt();
$otInfo["refOt"] = trim($ot->VBELN);
// Go through partner to get the wanted items
foreach ($ot->E1ADRM1 as $partner) {
switch ($partner->PARTNER_Q) {
case "OSO":
$otInfo["codeLoader1"] = trim($partner->E1ADRE1->EXTEND_D);
break;
case "OSP":
$otInfo["refShip"] = trim($partner->PARTNER_ID);
// get the shipping info if not already fetched
if(!isset($shippingPoints[$otInfo["refShip"]])) {
$shippingPoints[$otInfo["refShip"]] = Whouses::getWhouseAddressByCode($otInfo["refShip"]);
}
// assign values
$otInfo["brandNameShip"] = $shippingPoints[$otInfo["refShip"]]["name"];
$otInfo["addrShip1"] = $shippingPoints[$otInfo["refShip"]]["address"];
$otInfo["cityShip"] = $shippingPoints[$otInfo["refShip"]]["city"];
$otInfo["zipShip"] = $shippingPoints[$otInfo["refShip"]]["zipcode"];
$otInfo["countryShip"] = $shippingPoints[$otInfo["refShip"]]["country"];
break;
case "WE":
$otInfo["refDeliv"] = trim($partner->PARTNER_ID);
$otInfo["addrDeliv1"] = trim($partner->STREET1);
$otInfo["cityDeliv"] = trim($partner->CITY1);
$otInfo["zipDeliv"] = trim($partner->POSTL_COD1);
$otInfo["countryDeliv"] = trim($partner->COUNTRY1);
default:
// do nothing
break;
}
}
// Go through the dates info to get the wanted items
foreach ($ot->E1EDT13 as $qualf) {
switch ($qualf->QUALF) {
case "006":
$dtDeliv = trim($qualf->NTANF);
$timeDeliv = trim($qualf->NTANZ);
$otInfo["initialDtDeliv"] = convertToOtDateFormat($dtDeliv, $timeDeliv);
break;
case "007":
$initialDtShip = trim($qualf->NTANF);
$timeInitialDtShip = trim($qualf->NTANZ);
$otInfo["initialDtShip"] = convertToOtDateFormat($initialDtShip, $timeInitialDtShip);
break;
default:
// do nothing
break;
}
}
}
Hope this'll help someone!
