[librecat-dev] selection of multiple MARC fields

[Patrick Hochstenbach]

Hi

The default behavior of marc fixes is to work in the context of the complete MARC record:

	marc_match(‘035a/0-11’, ….)

will first gather the substrings in /all/ 035 fields and then tries to match it against a regular expression.

Use the ‘marc_each’ bind to execute the marc fixes in the context of each MARC field seperately :

      do marc_each()
	# If the current field is 035a and 0-11 matches…
        if marc_match('035a/0-11','(DE-188-SEP)’)
	       marc_map('035a/12-30','sep-id’)
        end
      end

Cheers
Patrick
