You're almost there - all you have to do is include a check that the string is not empty (which can be accomplished with a positive lookahead for .{1,10} right after the ^), and check that its first digit string has at most 10 characters (just use a {0,10} quantifier for the digits). Also note that [0-9] simplifies to d.



In order to also exclude trailing dots, repeat the digit after the dot with {1,2} instead of {0,2}:



^(?!$)d{0,10}(?:.d{1,2})?$
