In the case of branching constructs like the following: /a(b?ST When "S" can match, it is a better match than when only "T" can match._ "Food is on the foo table.To escape it, you can precede it with a backslash ) or enclose it within square brackets ).For example: / 2001 chrysler town and country manual (Y) # group 1 ( # group 2 (X) fifa 12 patch november game update # group 3 g-1 # backref to group 3 g-3 # backref to group 1 ) /x would match the same as Y) ( (X) g3.
