Hi Christian,

Thank you for your help. Now the current version of Parse.hs (http://code.google.com/p/hgmltracer/source/browse/trunk/hGmlTracer/src/Gml/P...) works well for the test file fact.gml.

spaces char end

The idea is to call spaces _after_ every token.

In other words "spaces" before "char end" is not needed.

So the keyword parser should be extended by ">> spaces" and also the number, char, string, binder and identifier parsers.

This is not necessary since you skip spaces after parseGml'. "skip (A <|> B)" is better than "skip A <|> skip B". C.
