PHP SimpleXML Children Node Data Extract

Question

I have been trying extract the node data's children using a foreach loop. I can get the main node data without problems, but the child data only gets the first data set then repeats. can someone maybe tell me what i am doing wrong? I got the example going from the offical documentation: http://php.net/manual/en/simplexmlelement.children.php

This is my test xml

<Result>
<Result_Data>
    <Root_XML>
        <Stock>
            <Stock_Code>28</Stock_Code>
            <Barcode>28</Barcode>
            <Multiple_Barcodes>
                <Barcode>BARCODE1</Barcode>
                <Barcode>BARCODE2</Barcode>
            </Multiple_Barcodes>

            <Onhand>0</Onhand>
        </Stock>            
    </Root_XML>
</Result_Data>

This is my php code

$file = file_get_contents('play.xml', true);  
$XMLtoSAVE = new SimpleXMLElement($file);
foreach ($XMLtoSAVE->Result_Data->Root_XML->Stock as $element) {
echo $element->Stock_Code . "\n";

    //Child Node Data - Barcode
    foreach ($XMLtoSAVE->Result_Data->Root_XML->Stock->Multiple_Barcodes as $element) {
    echo $element->Barcode . "\n";
    }


}   

This is the output:

28

BARCODE1

123

BARCODE1

Expected Output:

28

BARCODE1

BARCODE2

123

BARCODE123

BARCODE124

Answer 1

In the inner loop use foreach ($element->Multiple_Barcodes->Barcode as $barcode) { echo $barcode; }.
