Say I have some string that begins with an arbitrary sequence of characters and then alternates repeating the letters 'a' and 'b' any number of times, e.g.
"xyz123aaabbaabbbbababbbbaaabb" I'm looking for a regular expression that matches the first, and only the first, sequence of the letter 'a', and only if the length of the sequence is exactly 3. Does such a regular expression exist? If so, any ideas as to what it could be? -- Roger L. Cauvin [EMAIL PROTECTED] (omit the "nospam_" part) Cauvin, Inc.
