Search and replace in a UEL expression

[ericsnyder]

I have a variable that holds email addresses like this:

[address@domain.com, address1@domain.com, address2@domain.com]

This might be a really simple question but how would I remove the brackets using a UEL expression?

Basically set up a bean (POJO) and use it to create what I needed.
