Perl REGX match between parentheses
 
I have a script that reads a file that looks as such.
First(James) Zip(1234)
Last(Jones)

I have function that you pass a item to find (such as "First"). A simple regex parses the file and returns the data. /$data\((w+)\)/

This works find, but now there are some items that aren't words, some have spaces and commas in them. How can I return the data between the parentheses regardless of what text is between them?

Code:

/$data\(([^)]+)\)/

The regular expression can be:

Code:

/\((.*?)\)/
#  $1

- '$1' will contain the data you need to be extracted between parenthesis.

Shouldn't that be:
Code:

/$data\(([^)]+)\)/
??

I use the same pattern myself for parsing text with opposing tokens like parentheses, curly braces, and brackets.

If we are generalizing, then why not http://perldoc.perl.org/Text/Balanced.html ?

Thanks theNbomr, I've changed it.
