[Koha] Dealing with bad MARC records

[Kevin O'Rourke]

This question is not directly related to Koha itself, but to preparing 
MARC records for import.

Some of the records we've been downloading from Libraries and Archives 
Canada contain a "5||" (two pipe characters) tag with information about 
translation.  As far as I can tell this is not valid MARC.

I developed a little Java program to pre-process records before 
importing into Koha, using the marc4j library to read MARC.  This 
library refuses to read records containing non-numeric tags, causing us 
problems.

Can anyone recommend any tools for ensuring that a MARC record contains 
only valid MARC?  I could use MarcEdit to 'break' the files, edit out 
the bad tags and then re'make' them but this is a bit complicated, 
time-consuming and error-prone.
