I am familiar with ^ in regular expressions negating a character class as well as requiring that a match must come at the start of the line. But I am having trouble discerning what ^* in certain contexts is supposed to indicate. I know that the expression (1^*(01^*01^*)^*) \cup (0^*(10^*10^*)^*) matches all strings in a binary alphabet with an even number of 0's or 1's, but I guess I'm having trouble talking myself from the regular expression to an informal description of what it's matching. Similarly, I'm having trouble deducing what would match the expression (a|b)^*ba(ab*|ba*) particularly as relates to (a|b)^*
Any guidance welcome. Jared __________View the list's information and change your settings at //www.freelists.org/list/programmingblind
