Hi Mark and happy new year! For small tags a simple rule, uggly but very cheap, may work: /Src|sRc|srC|...... and son on.... number of letters to the power of 2... not usefull for long tags but cheap in terms of regex steps. A more ellaborated regex... The next rules are far from perfect but can detect "something that looks like" mixed upper and lower case HTML tags in the pristine body. full __MIXED_UPLOCASE_SRC /(?=(?i:src))(?!src|SRC)...\s*=/tflags __MIXED_UPLOCASE_SRC multiple maxhits=2 full __MIXED_UPLOCASE_HREF /(?=(?i:href))(?!href|HREF)....\s*=/tflags __MIXED_UPLOCASE_HREF multiple maxhits=2 meta MIX_UPLOCASE_HTAGS __MIXED_UPLOCASE_SRC >1 && __MIXED_UPLOCASE_HREF >1describe MIX_UPLOCASE_HTAGS MIX OF UPPER AND lower LETTERS in HTML TAGSscore MIX_UPLOCASE_HTAGS 1 You can also check for invalid Base64 characters and and invalid Base64 line lenght... if all of them match... "Hasta luego Lucas".... or as Rupert Gallagher says: easter eggs... :-) hope they help you... -----PedroD
