MARC::File::XML and parsing.

[Henri-Damien LAURENT]

hi,
I have some problems with Marc::File::XML parser.

Take those two xml records.
Despite the fact that I agree that there are odd characters in some
subfields.
I am wondering why, since those characters are UTF8, MARC::File::XML
should drop them when parsing.
Is there a reason why MARC::File::XML considers only a very strict
subset of utf-8 as valid ? (For instance no linebreak, no ...) ?

Couldnot it  say "OK It is XML record, encoded UTF8, i take it for
granted and no matter if there are "odd" characters" ?
This could be a really BIG trouble for kanjis or hindu languages imho.

MARC::File::XML odd conversion to usmarc

[Henri-Damien LAURENT]

xml record :

http://www.w3.org/2001/XMLSchema-instance";
 xsi:schemaLocation="http://www.loc.gov/MARC21/slim http://www.loc.gov/
standards/marcxml/schema/MARC21slim.xsd"

Here is part of my code :
my $record;
eval {
$record =
MARC::Record->new_from_xml($marcxml,'UTF-8',"UNIMARCAUTH");
$record->encoding('UTF-8');
};
if($@){
print "  There was some pb getting authority :
".$authid."\n";
}
my $leader=$record->leader;
substr($leader,0,5)=' ';
substr($leader,10,7)='22 ';
$record->leader(substr($leader,0,24));
print $record->as_usmarc();

But it was not a single record. It was part of a batch.
And it seems that trying to decode the marc record on its own leads to
problems.

Anyway, why is there a change in leader  from 00154nx  a2200073   4500
to 00162lbána2200073uel4500 ?
This leads to problem with MARC decoding.
Is there something to do about it ?
Coud MARC::File::XML be a little more verbose about errors ?
