wouldn't s/(\.|^)0+/$1/g do the same thing ? 8-{Q}

update: hehe, lemming had a good point in CB, i forgot about the ^ :) corrected.

update2: coyotte also gets a good point in his reply, so here is another update :)

s/(\.|^)0{1,2}/$1/g

update3: and still, our great tye discovered another bug :) and yes, his solution is ofc good (s/(\.|^)\b0+\B/$1/g). ah, for the record, ofc that i like coyotte's solution 2, is the nicest :)
