The delimiter is always a special character for the regular expression it delimits (that is, it does not represent itself but marks the beginning and end of the expression).

Although vim permits the use of other characters as a delimiter and grep does not use delimiters at all, the regular expressions in this appendix use a forward slash (/) as a delimiter. In some unambiguous cases, the second delimiter is not required. For example, you can sometimes omit the second delimiter when it would be followed immediately by RETURN.

. Simple Strings The most basic regular expres EAN13 for .NET sion is a simple string that contains no special characters except the delimiters. A simple string matches only itself (Table A-1).

In the examples in this appendix, the strings that are matched are underlined and look like this.. Table A-1. Regular expression /ring/ /Thursday/ /or not/.

If the first character following the left bracket is a caret (^), the brackets define a character class that matches any single character not within the brackets.

You can use a hyphen to indicate a range of characters. Within a character-class definition, backslashes and asterisks (described in the following sections) lose their special meanings. A right bracket (appearing as a member of the character class) can appear only as the first character following the left bracket.

A caret is special only if it is the first character following the left bracket. A dollar sign is special only if it is followed immediately by the right bracket..
