Hi,
I have a regex problem I need some assistance with.

I have an array that contains data an example of which looks like this 
@array=('GAP_SPAN09 - GAP SPAN base (Scratch Testing [TSMC11] : tsmc11
+_wld(sxfatd12j)) GAP_SPAN03 - GAP SPAN base (DFD E2E Testing [TSPAN04
+] : tspan04-dfdint-wld(sxfamd6f)) POS_WLI02 - POS_WLI02 Web Logic Int
+egrator');

[download]
I need to be able to create a new list from this that looks like this 
@newarray=('GAP_SPAN09,GAP_SPAN03,POS_WLI02');

[download]
So the elements I require are those which appear before a " - " (space hyphen space") and these need to be put into a comma delimited list as in the example.
My attempts so far to figure this out with my limited perl knowledge have been wildly off the mark.
Any help would be most welcome.
