encode/decodeXMLEntities

Followup - This works for me: Modification of XML/Tree/Node.php function encodeXmlEntities($xml)

        $newstr="";
        for ($i=0; $i<strlen($xml); $i++)
        {
           // substring is character safe with mbstring overloading...
           $c=substr($xml,$i,1);
           $x=strpos($chrs,$c);  // this is broken if the double-byte character is a sequence in the above array
                                 // any suggestions?  can I check if only one byte long?  how?
           if ($x===false) $newstr.=$c; else $newstr.=$repchrs[$x];
        }
        return $newstr;
    }

But I need help finishing... Any way to speed this up? Seems like a slow way to do it...but...may be the only way... And...need to fix a the bug noted above... I tried to be clever doing strpos...but...think I may need to change my mind and scan an array myself.. any help?
