从$ node-> getElementsByTagName获取id值

Question

I'm looping over a array like so:

   $objDOM->load("URL");
         foreach ($objDOM->getElementsByTagName('CRPublication') as $node) {
                $itemVacature = array (
                'naam' => $node->getElementsByTagName('titleInformation')->item(0)->nodeValue
         }

Now the loaded XML node has an dynamic id. Is it possible to get the value from the id where getElementsByTagName is titleInformation?

The xml node I need to get the id from looks like so:

<createdBy>
<CRUser id="122"></CRUser>
</createdBy>
<modifiedBy>
<CRUser id="122"></CRUser>
</modifiedBy>
<owner>
<CRUser id="122"></CRUser>
</owner>

As you can see I only get the id from this external company. I have to convert these id's to values that make sense.

Thanks in advance!

Example of loop on a loaded an XML object using DOM Document having parent,child and grand-child structure.

$xml ='<?xml version="1.0" encoding="utf-8"?>
<root>
    <Parent>
        <child>child 1</child>
        <child>child 2</child>
        <child>child 3</child>
        <subParent>
            <Grandchild>Grandchild 1</Grandchild>
            <Grandchild>Grandchild 2</Grandchild>
            <Grandchild>Grandchild 3</Grandchild>
        </subParent>
    </Parent>
    <Parent>
        <child>child 4</child>
        <child>child 5</child>
        <child>child 6</child>
        <subParent>
            <createdBy>
                <CRUser id="122"></CRUser>
            </createdBy>
            <modifiedBy>
                <CRUser id="122"></CRUser>
            </modifiedBy>
            <owner>
                <CRUser id="122"></CRUser>
            </owner>
        </subParent>
    </Parent>
</root>';
    $doc = new DOMDocument();
    $doc->preserveWhiteSpace = false;
    $doc->loadXML($xml);
    $i=0;
    while(is_object($obj = $doc->getElementsByTagName("Parent")->item($i))) {
        foreach($obj->childNodes as $nodename) {
            if($nodename->nodeName=='subParent') {
                foreach($nodename->childNodes as $subNodes) {
                    if($subNodes->nodeName=='owner') {
                        if(!empty($subNodes->childNodes['CRUser']->getAttribute("id"))) {
                            echo $subNodes->childNodes['CRUser']->getAttribute("id")."
";
                        }
                    }
                    if($subNodes->nodeName=='createdBy') {
                        if(!empty($subNodes->childNodes['CRUser']->getAttribute("id"))) {
                            echo $subNodes->childNodes['CRUser']->getAttribute("id")."
";
                        }
                    }
                    if($subNodes->nodeName=='modifiedBy') {
                        if(!empty($subNodes->childNodes['CRUser']->getAttribute("id"))) {
                            echo $subNodes->childNodes['CRUser']->getAttribute("id")."
";
                        }
                    }
                }
            } else {
                if(!empty($nodename->getAttribute("id"))) {
                    echo $nodename->getAttribute("id")."
";
                }
            }
        }
    $i++;
    }
    /* Output
    122
    122
    122
    */
