Hi Jason, This is not possible yet, but I submitted an improvement for Marc modification templates on bug 11319. It will allow to do something like: replace '^' with 'BEGIN' and '$' with 'END' If 245$a contains 'title', you will be allow to add a rule as: copy field 245$a to 245$a using regex s/^/new_value/ Regards, Jonathan 2014-03-07 22:32 GMT+01:00 Jason Sherman <jsherman@usao.edu>:

Hi all,

I'm pretty pumped about the marc mod templates, but I have one question. Has anyone been able to use regex backreferences? Or more broadly, is anyone using the mod templates to concatenate values?

I'm trying to prepend a value to a subfield, but when I look at the modified marc in the staged records list, I keep getting a literal instead of a backreference.

Lets say subfield contains the following: some-old-value

If I run a move or copy action against it using regex, I would expect the following expression: s/(.+)/some-new-value--$1/

to result in the following output: some-new-value--some-old-value

instead, I get: some-new-value--$1

Note: I've also tried using other capture group notation (\1 \g1) instead of the dollar sign and I still get a literal.

Thanks!
