Hi All,

I have problem to split a string like this:


and I want to get all substrings with only one '.' in mid. so the
output I expect is :

'abc.defg', 'defg.hij', 'hij.klmnop'

a simple regular expression '\w+.\w' will only return:
'abc.defg', 'hij.klmnop'

is there a way to get 'defg.hij' using regular expression?
