foreach loop is echoing the results of the first submission - php

Question

I'm working with data from Formstack's REST API. Everything is in XML format. I wrote some PHP to process it, and for some reason when I echo $valueVar in a foreach loop only the value from the first entry is returning for each of the three entries. I really don't know why the string isn't getting replaced. Could someone please shed some light on what I'm doing wrong.
Thank you!
PHP Output
Formstack API XML Output
foreach($xml->submissions->submission as $submission) {
foreach($xml->submissions->submission->data->XML_Serializer_Tag as $serializer) {
$fieldeVar = (string)$serializer->field;
$valueVar = (string)$serializer->value;
if ($fieldeVar=="95733876") {
echo $valueVar;
break;
}
}
}

I think this is a simple case of your 2 loops clobbering each other. Notice how you're defining the inner loop as foreach($xml->submissions->submission->.... That will always grab the first instance. It should be using $submission which your outer loop is setting up for you.
Just change
foreach($xml->submissions->submission as $submission) {
foreach($xml->submissions->submission->data->XML_Serializer_Tag as $serializer) {
to this
foreach ($xml->submissions->submission as $submission) {
foreach ($submission->data->XML_Serializer_Tag as $serializer) {
Output
prefix = Dr first = Argnes last = Acmefirst = Bobby last =
Leamalotfirst = Tina last = Students
