The MARC-XML distribution is an extension to the MARC-Record distribution for
working with MARC21 data that is encoded as XML. The XML encoding used is the
MARC21slim schema supplied by the Library of Congress. More information may
be obtained here: http://www.loc.gov/standards/marcxml/
You must have MARC::Record installed to use MARC::File::XML. In fact
once you install the MARC-XML distribution you will most likely not use it
directly, but will have an additional file format available to you when you
This version of MARC-XML supersedes an the versions ending with 0.25 which
were used with the MARC.pm framework. MARC-XML now uses MARC::Record

Sets or returns the default record format used by MARC::File::XML. Valid
formats are <B>MARC21B>, <B>USMARCB>, <B>UNIMARCB> and <B>UNIMARCAUTHB>.
Returns a MARC::Record object serialized in XML. You can pass an optional format
parameter to tell MARC::File::XML what type of record (USMARC, UNIMARC, UNIMARCAUTH) you are
Returns a MARC::Record object serialized in XML without a collection wrapper.
You can pass an optional format parameter to tell MARC::File::XML what type of
record (USMARC, UNIMARC, UNIMARCAUTH) you are serializing.
If you have a chunk of XML and you want a record object for it you can use
this method to generate a MARC::Record object. You can pass an optional
encoding parameter to specify which encoding (UTF-8 or MARC-8) you would like
the resulting record to be in. You can also pass a format parameter to specify
the source record type, such as UNIMARC, UNIMARCAUTH, USMARC or MARC21.
my $record = MARC::Record->new_from_xml( $xml, $encoding, $format );
Note: only works for single record XML chunks.
If you want to write records as XML to a file you can use out() with write()
to serialize more than one record as XML.
A constructor for creating a MARC::File::XML object that can write XML to a
file. You must pass in the name of a file to write XML to. If the $encoding
parameter or the DefaultEncoding (see above) is set to UTF-8 then the binmode
of the output file will be set appropriately.
my $file = MARC::File::XML->out( $filename [, $encoding] );
Used in tandem with out() to write records to a file.
my $file = MARC::File::XML->out( $filename );
$file->write( $record1 );
$file->write( $record2 );
When writing records to disk the filehandle is automatically closed when you
the MARC::File::XML object goes out of scope. If you want to close it explicitly
use the close() method.
If you want to generate batches of records as XML, but dont want to write to
disk youll have to use header(), record() and footer() to generate the
$xml = join( "\n",
MARC::File::XML::record( $record1 ),
MARC::File::XML::record( $record2 ),
MARC::File::XML::record( $record3 ),
Returns a string of XML to use as the header to your XML file.
Returns a string of XML to use at the end of your XML file.
Returns a chunk of XML suitable for placement between the header and the footer.
You probably dont ever want to call this method directly. If you do
you should pass in a chunk of XML as the argument.
It is normally invoked by a call to next(), see MARC::Batch or MARC::File.
