Parameters for StringSearcher

​@gg33130 

I think in the regular expression parameter of StringSearcher “\d+_ZONE_URBA_\d+” should do the trick.

• \d+ — matches one or more digits before the constant.

• _ZONE_URBA_ — matches the exact constant string.

• \d+ — matches one or more digits after the constant.

If you know the number of digits (e.g., 9 digits before and 9 digits after ZONE_URBA), the reg exp would be

\d{9}_ZONE_URBA_\d{9}

Hope that helps.

Thanks a lot ! It works and I got good results !

Now the problem is my results give many polygons with different shapes.

I just want to keep the polygons which have a certain shape.

In my exemple below I would like to keep only the polygon in brown and to delete all the others (in blue which are roads in reality).

I don’t know if a transformer can allow me to choose polygons according to theirs shapes ? 

Thanks a lot ! Have a good day !

​@gg33130 If you can filter the polygons of interest based on an attribute, then try TESTER transformer.

Since you mentioned that the blue ones are roads, you could filter them, if any attribute data is available that denotes that it is a road.
