Back Porting Reg Ex matching functionality from v15/01a to v14/06a

Hi David,

Hope all is going well.

I would like to use Reg Ex mapping on some of my sites using v14/06A and I wondered if you could tell me if there is a simple way to implement just the reg ex functionality of the latest 15/01a PT version into a 14/06 site? The site is currently using the MD5 matching functionality which you kindly wrote for me quite a while back so ideally I would like to use the reg ex matching as an extension to this if this sounds possible?

Thanks in advance.

Best regards

Chris
