pyqt3 readline question

I have a text file with most lines that resemble:

#1003 = 0.0139 ( X points to inches scale factor =1/72 )
#1004 = 0.0139 ( Y points to inches scale factor =1/72 )
M3 S15000 ( spindle cw at 15000rpm )
G4 P2 ( let spindle get to speed )
M7 ( mist coolant on )
G01 Z#1000 F#1001

G00 Z#1000
G00 X[#1003*300.133] Y[#1004*2343.29]
G01 Z#1002
G01 X[#1003*300.188] Y[#1004*2343.29]
G01 X[#1003*300.246] Y[#1004*2343.29]
G01 X[#1003*300.246] Y[#1004*2343.29]
G01 X[#1003*300.246] Y[#1004*2343.29]
G01 X[#1003*301.453] Y[#1004*2343.29]
G01 X[#1003*302.641] Y[#1004*2343.26]
G01 X[#1003*303.855] Y[#1004*2343.22]
G01 X[#1003*305.043] Y[#1004*2343.15]
G01 X[#1003*306.227] Y[#1004*2343.1]

What I need to do is read each line one at a time and IF the line starts with a "G0" it gets read otherwise it's skipped and in the line it reads eg:G01 X[#1003*300.188] Y[#1004*2343.29] would take 1003*300.188 (from the X) send it to LCDNumber55.display and 1004*2343.29 send it to LCDNumber56.display and then same for "Z" value to LCDNumber57.display same process for all three variables on each line even if "Z" is missing. If the readout is to fast can I put an adjustable time variable between each readline to slow it down?

Thanks

I was thinking that to be inline with other gcode layouts that all three coordinates may not appear on the same line the one factor that is always consistent is the Xinterger Yinteger Zinteger so it would be better to readline a line and send the integer that follows X to lcdnumberdisplay and the same for the other Y and Z integers even if they appear on a line that does not start with the "G0".so the trigger would be X integer and a white space to end the trigger and same for Y and Z.

Here is a sample of another file layout to go with the above :

F200.0
S1000.0
G00 Z6.0000
X-6.5000 Y-5.2000
G01 Z4.2000
X6.5000
G00 Z6.0000
Y-4.3000
G01 Z4.2000
X-6.5000
G00 Z6.0000
Y-3.4000
G01 Z4.2000
X6.5000
G00 Z6.0000
Y-2.5000

So as you can see it's more universal to grab the integer after the X and send it to the lcd display and so on for Y and Z if the actual XYZ are used as the trigger start point.
