# A notable difference between PCRE and .NET. According to

|
# If you make a subroutine call to a non-unique named

|
# subpattern, the one that corresponds to the first
|
|||
|
# occurrence of the name is used. In the absence of
|
|||
|
# duplicate numbers (see the previous section) this is
|
|||
|
# the one with the lowest number.
|
|||
|
# .NET takes the most recently captured number according to MSDN:
|
|||
|
# A backreference refers to the most recent definition of
|
|||
|
# a group (the definition most immediately to the left,
|
|||
|
# when matching left to right). When a group makes multiple
|
|||
|
# captures, a backreference refers to the most recent capture.
