Can anyone tell me what this is doing?

[buildakicker]

foreach($indexXML->document->document as $doc) {

    if(strcmp($doc->DocumentKey[0]->tagData, $docType) == 0) {

$viewMapping = $doc;

$viewXMLFile = $doc->ViewXML[0]->tagData;

break;

}

It appears to be looping through XML data.

Hi, sorry, yes it is looping through data. The one part I don't get is the:

 

foreach($indexXML->document->document as $doc) {

    if(strcmp($doc->documentkey[0]->tagData, $docType) == 0) {

$viewMapping = $doc;

$viewXMLFile = $doc->viewxml[0]->tagData;

break;

}

}
