[FWTools] OGR2OGR QUOTES ISSUE

[Matt Wilkie]

  Hi Susana,

You're missing the beginning single quote (') before C:/Archivos.... and 
I don't think you need to escape the inner double quote ("), so instead of

    '\"LAYER= \'line\'\"'

try

    '"LAYER=\'line\'"'

Also it would be easier to read the code if you did something like:

ogr2ogr = 'C:/Archivos de programa/FWTools2.4.7/bin/ogr2ogr'
inshape = line + '.shp'
outshape = b + '.shp'
query = '-where "LAYER=\'line\'" '

p = subprocess.Popen([ogr2ogr, inshape, query,  outshape])

hope that helps,

matt wilkie
