NAME

       Catmandu::Fix::marc_decode_dollar_subfields - decode double encoded dollar subfields

SYNOPSIS

           marc_decode_dollar_subfields()

DESCRIPTION

       In some environments MARC subfields can contain data values that can be interpreted as
       subfields itself. E.g. when the 245-$a subfield contains the data:

          My Title $h subsubfield

       then the $h = subsubfield will not be accessible with normal MARC processing tools.  Use
       the 'marc_decode_dollar_subfields()' fix to re-evaluate all the MARC subfields for these
       hidden data.

METHODS

   marc_decode_dollar_subfields()
       Decode double encoded dollar subfields into real MARC subfields.

INLINE

       This Fix can be used inline in a Perl script:

           use Catmandu::Fix::marc_decode_dollar_subfields as => 'marc_decode_dollar_subfields';

           my $data = { record => [...] };

           $data = marc_decode_dollar_subfields($data);
