Am cautat pe net si numa nu am gasit nici o explicatie ...

Salut
Din mesajul de eroare se intelege ca sirul cu documentul xml contine caractere nevalide utf-8 (0xB4 0x73 0x20 0x4E).
Incearca sa convertesti sirul in format valid utf-8, cu functa utf8_encode().

$xml = simplexml_load_string( utf8_encode($sir_xml) );
