XML转换为数组函数



function xml2array($originalXML, $attributes=true) 
{ 
        $xmlArray = array(); 
        $search = $attributes ? '|<((\S+)(.*))\s*>(.*)</\2>|Ums' : '|<((\S+)()).*>(.*)</\2>|Ums';

        $xml = preg_replace('|>\s*<|', ">\n<", $originalXML); // one tag per line 
        $xml = preg_replace('|<\?.*\?>|', '', $xml);            // remove XML declarations 
        $xml = preg_replace('|<(\S+?)(.*)/>|U', '<$1$2></$1>', $xml); //Expand singletons 
       
        if (! preg_match_all($search, $xml, $xmlMatches)) 
                return trim($originalXML);      // bail out - no XML found
