I have the following CNC machine code: 
N38 * TOOL 11: 0.125 DIA. FINISH ENDMILL
N39 M6T11
N40 E1
N41 S15000M3M7
N42 G17G90G0G8X-5.58Y-18.
N43 Z0.05H11
N44 G82G98X-5.58Y-18.Z-0.2R+0.01P50F100.
N45 X-3.171
N46 X-1.025
N47 X0.887
N48 X3.371Y-18.688
N49 Y-17.312
N50 X5.46Y-18.

The N's are line numbers that need to be stripped out. The astrix are comments that need to be replaced with ! All letters need to be stripped and only the numbers after X,Y and Z must be left in a space delimited string. So the above should come out like: 
! TOOL 11: 0.125 DIA. FINISH ENDMILL 5.58 -18. 0.05 -5.58 -18. -0.2 1.
+025 0.887 3.371 -18.688 -17.312 5.46 -18.

I have hundreds of files with thousands of lines of this code that need to be parsed in this way. I need help with search and replace and inserting spaces etc. I would be eternally greatful for any help offered to help me get started on some code that might accomplish this! Thank you in advance, Blaine
