[osmosis-dev] tagtransform: copy-matched does not removes tags when no tag on entity is matched

[Felix Schneider]

Hi,

I'm  trying to filter all tags in an .osm file on a whitelist basis. This works fine when at least one tag on an entity is matched, but fails when an entity has only tags that should be removed. 

I think the problem is around TransformHelper.java:132, but I have no clue how to fix this. 

Sample files and sample outputs are attached.

Regards,
Felix Schneider
