Re^3: Recursive search in nested hash for selective keys

I'd pass $key_val in as a third parameter (actually the second parameter with $key the last). However, that doesn't seem to be the real problem. I suspect all you need to do is assign an empty hash to $key_val between iterations to clear the previous contents.

True laziness is hard work

I passed a third parameter as $call with a value "main" if called from outside or value "sub" if called recursively within. `$key_val = {} if ($call eq "main");` [download]	[reply] [d/l]
