For the sake of offering a completely different approach to the problem of parsing into a nested
array, here is teh solution I came up with. Works pretty well, and reasonably fast, though maybe a
little memory intensive:
class xml2array{
/* This class parses XML tags into a recursive, associative array with the tags as the associative
array elements names.
Function names are descriptive;
if it encounters multiples of the same tag within a stream, it enumerates them as a sub array under
the tag thus:
Array (
[Lvl1tag] => Array (
[0] => Array(
[Lvl2tag] = "foo")
[1]=> Array(
[Lvl2tag] = "bar")
)
)
It tries to detect when there is only one copy of a tag under another, and concatinate properly.

function readxmlfile($xmlfile){ // reads XML file in and returns it
$xmlstream =fopen($xmlfile,r);
$xmlraw=fread($xmlstream,1000000);
fclose($xmlstream);
return $xmlraw;
}
function parseXMLintoarray ($xmldata){ // starts the process and returns the final array
$xmlparser = xml_parser_create();
xml_parse_into_struct($xmlparser, $xmldata, $arraydat);
xml_parser_free($xmlparser);
$complete = $this->subdivide($arraydat);
return $complete;
}
function subdivide ($dataarray, $level = 1){
foreach ($dataarray as $key => $dat){
if ($dat[level] === $level && $dat[type] === "open"){
$toplvltag = $dat[tag];
} elseif ($dat[level] === $level && $dat[type] === "close" &&
$dat[tag]=== $toplvltag){
$newarray[$toplvltag][] = $this->subdivide($temparray,($level +1));
$keys = array_keys($newarray[$toplvltag]);
if (count($keys)== 1 && is_int($keys[0])){
$tmp = $newarray[$toplvltag][0];
unset($newarray[$toplvltag][0]);
$newarray[$toplvltag] = $tmp;
}
unset($temparray,$nextlvl);
} elseif ($dat[level] === $level && $dat[type] === "complete"){
$newarray[$dat[tag]]=$dat[value];
