将xml转换为数组

php代码

function xmlNameSpaceToArray(SimpleXmlIterator $xml, $nameSpaces=Null){
      $output = Null;
      $preparedArray = array();
      for($xml->rewind(); $xml->valid(); $xml->next()) {
            $key = $xml->key();
            if(!isset($preparedArray[$key])) { $preparedArray[$key] = array(); $i=0; }
            else $i = count($preparedArray[$key]);
            $simple = true;
            foreach($xml->current()->attributes() as $k=>$v) {
                $preparedArray[$key][$i][$k]=(string)$v;
                $simple = false;
            }
            if($nameSpaces) foreach($nameSpaces as $nid=>$name) {
            foreach($xml->current()->attributes($name) as $k=>$v) {
                $preparedArray[$key][$i][$nid.':'.$k]=(string)$v;
                $simple = false;
            }
            }
            if($xml->hasChildren()) {
                if($simple) $preparedArray[$key][$i] = xmlNameSpaceToArray($xml->current(), $nameSpaces);
                else $preparedArray[$key][$i]['content'] = xmlNameSpaceToArray($xml->current(), $nameSpaces);
            } else {
                if($simple) $preparedArray[$key][$i] = strval($xml->current());
                else $preparedArray[$key][$i]['content'] = strval($xml->current());
            }
            $i++;
      }
      $output = $preparedArray;
      return $preparedArray;
}
