RPG program: XML command error

I received an XML-document via mail, I detached it and placed it into the IFS.
Then I wrote an RPG-program where I used the XML-INTO command to read the XML-document.
But, when I run my program I always get the error “The XML parser detected error code 302″

I think there’s something wrong with the CCSID, the IFS-file is in CCSID 1252

Who can help me with this?

Thanks!
