How do I remove everything outside of parenthesis in a string using regex

Question

How do I remove everything outside of parenthesis in a string using regex. I'm just trying to get what's in the parenthesis.

I'm looping through a bunch of records. To keep things simple for this example, I'm using just 1 record (each record can have multiple values).

So if this my record string:

<cfset servicelist = "Orthopedic, Joint (AFDA); Orthopedic Surgery (ACDA)">

What regex do I add to this variable:

<cfset Codes = "">

I'm trying to grab the following codes out of the record:

(AFDA)(ACDA)

Answer 1

This should do it (\\(\\w+\\))

\\( matches the character ( literally (case sensitive)
\\w+ matches any word character (equal to [a-zA-Z0-9_] )
+ Quantifier — Matches between one and unlimited times, as many times as possible
\\) matches the character ) literally (case sensitive)

Also Try @WiktorStribiżew Example .*?(\\(\\w+\\))? ** and replace with $1 * (or \\1 in ColdFusion)

.*? matches any character (except for line terminators)
? Quantifier — Matches between zero and one times, as many times as possible
