[jQuery] parser error on well-formed xml

[tarini]

i use this xml saved locally in projects.xml

<?xml version="1.0" encoding="utf-8"?>
<projects>
        <project id="1">
                <name>Nome del progetto 1</name>
                <note>Note del progetto 1</note>
        </project>
        <project id="2">
                <name>Nome del progetto 2</name>
                <note>Note del progetto 2</note>
        </project>
</projects>


it's well-formed but IE v7 show me a parser error...

onError : function(xhr, st, er) {
   //st = "parsererror"; er=undefined
   alert("ERRORE:\nstatus: "+st+"\nerror: "+er);
}
