Hey Andy, That does sound like an annoying problem. Someone else might have a better answer, but I think I have a clever solution...
Instead of using MARC::File::XML directly, you can use MARC::Batch instead: my $batch = MARC::Batch->new( 'XML', $filename ); According to the MARC::Batch documentation, you can actually use a file handle instead of a file name: http://search.cpan.org/~gmcharlt/MARC-Record-2.0.7/lib/MARC/Batch.pm#new(_$type,_@files_) . You should be able to create an "in-memory" file handle that points to your scalar variable holding your XML. Like so: open(my $fh, "<", \$variable); You should be able to pass in the $fh to MARC::Batch like this: my $batch = MARC::Batch->new( 'XML', $fh ); Now I haven't tried this... but in theory it should work.
