PHP XML 2 Array Function
17
I've seen XML 2 Array functions done in other ways but this is the shortest implementation I've seen yet. I didnt write it myself though, but I thought I'd submit it for common good of this site. It uses regex and works prefectly.
function xml2array($xml) {
$xmlary = array();
$reels = '/<(\w+)\s*([^\/>]*)\s*(?:\/>|>(.*)<\/\s*\\1\s*>)/s';
$reattrs = '/(\w+)=(?:"|\')([^"\']*)(:?"|\')/';
preg_match_all($reels, $xml, $elements);
foreach ($elements[1] as $ie => $xx) {
$xmlary[$ie]["name"] = $elements[1][$ie];
if ($attributes = trim($elements[2][$ie])) {
preg_match_all($reattrs, $attributes, $att);
foreach ($att[1] as $ia => $xx)
$xmlary[$ie]["attributes"][$att[1][$ia]] = $att[2][$ia];
}
$cdend = strpos($elements[3][$ie], "<");
if ($cdend > 0) {
$xmlary[$ie]["text"] = substr($elements[3][$ie], 0, $cdend - 1);
}
if (preg_match($reels, $elements[3][$ie]))
$xmlary[$ie]["elements"] = xml2array($elements[3][$ie]);
else if ($elements[3][$ie]) {
$xmlary[$ie]["text"] = $elements[3][$ie];
}
}
return $xmlary;
}
$xmlary = array();
$reels = '/<(\w+)\s*([^\/>]*)\s*(?:\/>|>(.*)<\/\s*\\1\s*>)/s';
$reattrs = '/(\w+)=(?:"|\')([^"\']*)(:?"|\')/';
preg_match_all($reels, $xml, $elements);
foreach ($elements[1] as $ie => $xx) {
$xmlary[$ie]["name"] = $elements[1][$ie];
if ($attributes = trim($elements[2][$ie])) {
preg_match_all($reattrs, $attributes, $att);
foreach ($att[1] as $ia => $xx)
$xmlary[$ie]["attributes"][$att[1][$ia]] = $att[2][$ia];
}
$cdend = strpos($elements[3][$ie], "<");
if ($cdend > 0) {
$xmlary[$ie]["text"] = substr($elements[3][$ie], 0, $cdend - 1);
}
if (preg_match($reels, $elements[3][$ie]))
$xmlary[$ie]["elements"] = xml2array($elements[3][$ie]);
else if ($elements[3][$ie]) {
$xmlary[$ie]["text"] = $elements[3][$ie];
}
}
return $xmlary;
}

*
* xml2array will convert an XML document to an array.
* When attributes is true, resultant array will group by tag and exact-match attributes.
* When attributes is false, resultant array will group by tag and ignore attributes.
*
* The resultant array will be an associative array with tag (or tag + attributues) as the key. Each value
* will either be an XML2Array array (another associative array), or an array of value.
*
* Assumptions:
* 1. XML is well formed
* 2. White space is wrapped in CDATA
