RegEx pattern

[kri shan]

RegEx pattern for these Strings - one.two.three (or) onew.twos.trhhee.sdfour (or) fsdf.abcdr.trew.jffgh.qacd

This does not work  ((?:[a-z][a-z]+))

[Henry Wong]

Regular expression is more than just a pattern. How are you using it? find()? matches()? split()? replaceAll()? etc. etc. etc.

Perhaps you can elaborate a bit?

Maybe you need something like this i suppose:
([a-z][.a-z]+)

[Tim Moores]

Can you describe in words what you want to match? Is it "a sequence of lowercase letters, interspersed by dots, with at least one letter between dots"? If so, the dot should appear somewhere in the pattern (keeping in mind that a dot is a special pattern, and thus needs to be escaped to match a literal dot).

[fred rosenberger]

an example is terrific, but it is not a spec. This regex will work for your example, but it's almost without a doubt not what you want:

one\.two\.three|onew\.twos\.trhhee\.sdfour|fsdf\.abcdr\.trew\.jffgh.qacd

without a spec, you can't tell me the above is NOT what you want.
