I need a spreadsheet function or formula that can match by a pattern. Is
there such a thing? I have looked at FIND and SEARCH, but for these you need
to specify exactly your search string, you can't just indicate a pattern to
match.

For example, I need to test to determine if a cell contains a series of
numbers in the following pattern:

###.###.####.######.###.##.###

If so, then evaluate to ONE or TRUE or whatever, if not then ZERO or FALSE
or whatever. NOTE: The above string could contain any series of digits, I
just need to be sure all the "#" signs are numbers and that they are in the
pattern shown above.

Your assistance is greatly appreciated. Thanks in advance.
