           Summary: MARC record parsing from and to XML

On a Debian/Lenny, parsing of XML marc records encoded in UTF-8 doesn't work
properly depending of SAX parser used : PurePerl, Expat or LibXML. 

(1) Records are converted into XML string before being written in
bibliotems.marcxml. A function of MARC::File::XML us used in Biblio.pm:
$record->as_xml_record($encoding). With Expat or LibXML SAX Parser, encoding is
suppressed:

<?xml version="1.0" encoding=""?>

Consequently, records can't be read back from this biblioitems.marcxml. This is
a blocker bug.

(2) Records are created from XML string (biblioitems.marcxml). In Biblio.pm:

$record = eval {MARC::Record::new_from_xml( $marcxml, "utf8",
C4::Context->preference('marcflavour'))};

This function doesn't work properly with Expat or LibXML. UTF-8 extended
characters (é for example) are converted in their ISO-8859-1 counterpart.

Perl script attached allow to test those bugs.
