Re: [Haskell-cafe] Using regexps to filter data

Hi Michael I think you want to be using a one of the 'implementation' packages directly rather than Text.Regex.Base.RegexLike (from regex-base), for instance regex-posix. If you are searching a string you would want to import the Text.Regex.Posix.String module. Text.Regex.Base.RegexLike provides the interface, specific matchers (e.g. Posix or PCRE) provide the implementation. Best wishes Stephen
