VI Editor Script

I am using the function dbWriteSkill to dump the layout to a file and want to modify to just stretch the length and everything contact metal implant will also stretch.
I want to use the vi editor to modify.  Does anyone have a quick way to do it. For me I have to delete one by one and it take a longtime  
Below is the partial dump file
dbD_0xcd1f768 = dbCreatePolygon(dbD_0xcc0c42c list(16 252)
 list(2.650000e+01:2.930000e+01 2.240000e+01:2.930000e+01 2.240000e+01:7.000000e+00
      7.000000e+00:7.000000e+00 7.000000e+00:2.520000e+01 2.240000e+01:2.520000e+01
      2.240000e+01:2.930000e+01 2.900000e+00:2.930000e+01 2.900000e+00:2.900000e+00
      2.650000e+01:2.900000e+00 ) )
And this is what I want to change.
 (pcLayer = 16)
 (pcPurpose = "drawing")
 (pcInst = dbCreatePolygon(pcCellView
  list(pcLayer pcPurpose)
  list((26.5:(29.3 + l_float0offset))
      (22.4:(29.3 + l_float0offset))
      (22.4:7.0)
      (7.0:7.0)
      (7.0:(25.2 + l_float0offset))
      (22.4:(25.2 + l_float0offset))
      (22.4:(29.3 + l_float0offset))
      (2.9:(29.3 + l_float0offset))
      (2.9:2.9)
      (26.5:2.9)
  )
