The regular expression:
(?-imsx:address(.*)\d)
matches as follows:
NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
address 'address'
----------------------------------------------------------------------
( group and capture to \1:
----------------------------------------------------------------------
.* any character except \n (0 or more times
(matching the most amount possible))
----------------------------------------------------------------------
) end of \1
----------------------------------------------------------------------
\d digits (0-9)
----------------------------------------------------------------------
) end of grouping
----------------------------------------------------------------------
So .* (matching the most amount possible) followed by \d, a digit. If you want the digit to be captured, move it inside the parens. |
