Hello all,
I'm trying to delete a number of records from shapefile based on an
attribute. The strange thing that is happening is that feature count never
changes but if i make the same filter a second time the features are no
longer there. The code i'm using is below. I should be doing something
wrong for sure.
import os
from osgeo import ogr
path = 'C:\\datasets'
os.chdir(path)
shp = ogr.Open('locais.shp',1)
layer = shp.GetLayer(0)
print layer.GetFeatureCount()
layer.SetAttributeFilter('name ilike "nacional%"')
feat = layer.GetNextFeature()
while feat:
featId = feat.GetFID()
layer.DeleteFeature(featId)
feat = layer.GetNextFeature()
shp.Destroy()
Any suggestions? Thanks in advance.
Regards,
