Hello! I'm pretty new to perl and trying to write a regex to match a sequence. Basically, I have a number of cells and for each cell, a number of pins. The pins are listed as : 

  Pin:  U343.IN1  in
  Pin:  U713.INP  out
  Pin:  U714.QN

The one with out at the end or with nothing at the end are the output pins that I want to match. So I got to: 
/^[ ]+Pin:[ ]*([^\.]*)\.([^ ]*)$/  
--> Matches "  Pin:  U714.QN"
$1 = U714
$2 = QN

and

/^[ ]+Pin:[ ]*([^\.]*)\.([^ ]*)[ ]out/ 
--> Matches "  Pin:  U713.INP out"
$1 = U713
$2 = INP

[download]
Is there a way to combine these two so that it matches both? I tried using "|" to or them 
^[ ]+Pin:[ ]*([^\.]*)\.([^ ]*)$|^[ ]+Pin:[ ]*([^\.]*)\.([^ ]*)[ ]out

[download]
But if the second part of the expression matches, my () come in under $3 and $4. Basically, I want to match : 
  Pin:  U713.INP"endofstring or out"
With $1 = U713
$2 = INP

I'm sure there's some simple way to do this and im over complicating it but I cant figure it out for the life of me. A nudge in the rigth dorection would be greatly appreciated. Thanks!
