Jonathan, Many thanks. I get no errors on the command line or in the error log when I run the script. The file just executes with no output. If you have the time to run it, I've included the scriupt below, and have attached the name authority record it tries to process:
#! /usr/bin/perl
use strict;
use MARC::Record;
use MARC::Batch;
use MARC::File::XML;
use constant MAX => 20;
MARC::File::XML->default_record_format('UNIMARCAUTH');
my $batch = MARC::Batch->new( 'XML', 'name_authority_file');
while (my $record = $batch->next()) {
for my $field ($record->field("100")){
my $name= $field->subfield('a');
print "$name", "\n";
}
}
I think you're right about the LOC files -- they probably got the extra
spaces by accident. That's easy enough to fix.
As far as the name authorities go, if I can't get MARC::File::XML to process
them, I can always use XML::Tokeparser. Not as elegant, but it would get the
job done.

The prefixes are the namespace. The parser should be able to handle this,
but I don't honestly know if it does it correctly. What also might be the
problem is the second namespace in there. It might help us if you included
some information about what is not working (what error are you getting etc).
I don't have the time right now to run my own test, but actual error
messages might provide some clue.

Right, that comes from the MARC specification, there are 24 bytes.

Doubt it, again it doesn't have anything really to do with the XML spec but
the underlying xml record. More likely it is some error in creating the
files. Can't give any more info though, sorry.
