Processing ejfile.sda

I'm wanting to turn the Z totals from an ejfile.sda into a CSV I can pick up with a spreadsheet. I'm not interested in the amount, just in the Q lines and I only use a very limited range of PLUs. An example:

#005909   28/02/2016    0:36  
01 CLERK01              000000
       * Z 1*                 
PLU                           
          00001-         99999
PLU                           
 P00002                3.000 Q
TENNENTS                 *5.40
 P00012                4.000 Q
Beer 330                 *7.60
 P00013                3.000 Q
Beer 500                 *7.50
 P00022                8.000 Q
MALT WHISKEY            *20.00
 P00023                1.000 Q
OTHER SPIRITS            *1.90
 P00044                3.000 Q
WINE 1/4 BOTTLE          *6.60
 P00058                1.000 Q
SOFT DRINKS              *0.60
***TOTAL              23.000 Q
                        *49.60

Does anyone have anything, or a link to something, that could do this?

Putting out a line per Z per PLU would be fine e.g.
005909,28/02/2016 0:36,P00002,3.000
005909,28/02/2016 0:36,P00012,4.000

etc.

I have access to Windows and Linux PCs.
