Here's a quick way to dump the nodeValues from SimpleXML into an array using the path to each nodeValue as key. The paths are compatible with e.g. DOMXPath. I use this when I need to update values externally (i.e. in code that doesn't know about the underlying xml). Then I use DOMXPath to find the node containing the original value and update it.



<?php

function XMLToArrayFlat($xml, &$return, $path='', $root=false)

{

    $children = array();

    if ($xml instanceof SimpleXMLElement) {

        $children = $xml->children();

        if ($root){ // we're at root

            $path .= '/'.$xml->getName();

        }

    }

    if ( count($children) == 0 ){

        $return[$path] = (string)$xml;

        return;

    }

    $seen=array();

    foreach ($children as $child => $value) {

        $childname = ($child instanceof SimpleXMLElement)?$child->getName():$child;

        if ( !isset($seen[$childname])){

            $seen[$childname]=0;

        }

        $seen[$childname]++;

        XMLToArrayFlat($value, $return, $path.'/'.$child.'['.$seen[$childname].']');

    }

} 

?>



Use like this:



<?php

$xml = simplexml_load_string(...some xml string...);

$xmlarray = array(); // this will hold the flattened data

XMLToArrayFlat($xml, $xmlarray, '', true);

?>



You can also pull multiple files in one array:



<?php

foreach($files as $file){

    $xml = simplexml_load_file($file);

    XMLToArrayFlat($xml, $xmlarray, $file.':', true);

}

?>

The respective filename/path is thus prefixed to each key.
