hi, i need to search with regexps in strings, and want to know the index (of the source string) at which the regexp matched. and the length of the matched string, so with substitutions like \d+.. i'm kinda in a hurry on this one, would appreciate your immediate answer very much.. -- -------------------------------------------------------------- Rene Veerman, creator of web2.5 CMS http://mediabeez.ws/
