It is a "must" in the actual version: the length? of tag exclude "<>" chars, but form do not exclude them. Is the only exception in the any-string domain: length? #a ;== 1 length? form #a;== 1 length? %a;== 1 length? form %a;== 1 length? <a>;== 1 length? form <a>;== 3 Replace must know the length of the formed version. And: yes writing an full optimized version of replace is not a trivial task. --- Ciao Romano
