to think of many more uses of this function. I actually wrote it to do HTML fix-up, working with the TagSoup library. A few quick definitions and it becomes easy to express things like 'remove all FONT, BR and U tags; replace all instances of B with SPAN CLASS="important"...'; the task of repairing broken HTML and replacing simplistic markup with semantic markup. It's very powerful to have the separation between selection and transformation; it's quite easy to build up powerful libraries of selectors and use them with simple transformers.

hm. are you know about existence of haskell regexp libs? :) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
