How can I extract a string between matching braces in Perl?

Question

My input file is as below :

HEADER 
{ABC|*|DEF {GHI 0 1 0} {{Points {}}}}

{ABC|*|DEF {GHI 0 2 0} {{Points {}}}}

{ABC|*|XYZ:abc:def {GHI 0 22 0} {{Points {{         


        

Answer 1

You're much better off using a state machine than a regex for this type of parsing.
