Clip lines by overlapping polygons

Question

I want to cut a line shape into parts by polygon areas. No problem so far. But the polygons overlaps each other at the border. I need one line result for the whole area of every polygon. Any ideas for an automatic solution? Gdal ogr can't do it because of self intersecting polygons.

Answer 1

My solution is a GRASS GIS v.select iteration. So I get full line-shapes for each polygon, without getting self-intersection problems.
