The matching criterion implicitly matches from the beginning of the string, but not necessarily up to the end.
For instance,
123 will match the criterion 1 , but it will not match the criterion 2 .
If you want to match the whole string, you must end the criterion with “$”. For instance,
123
will not match the
criterion 1$ and will match the criterion 123$ .
Groups
A group is placed within parenthesis. It is used when replacing a string in a mapping. You can use up to nine
groups (defined by “\1” to “\9”) and matching is not case sensitive. “\0” represents the whole string. Lets say
for instance you have the following string:
9(123(45)6)
The following describes how the groups are replaced:
? Matches 0 or 1 occurrence of the previous item. For instance,
123?4
matches both
124
and
1234 .
+ Repeats the previous digit one or more time. For instance 12+345 matches 12345 , 122345 ,
etc. (but not 1345 ). If you use the + at the end of a number, it repeats the last number one or
more times. For instance:
12345+
matches,
12345
,
123455
,
1234555
, etc.
