Single-character regular expressions
This section describes the rules for creating regular expressions. You can use regular
expressions in the Search > Extended Find and Replace commands to match complex
string patterns.
The following rules govern one-character RegExp that match a single character:
Character classes
You can specify a character by using one of the POSIX character classes. You enclose
the character class name inside two square brackets, as in this Replace example:
"Allaire's Web Site","[[:space:]]","*","ALL")
This code replaces all the spaces with *, producing this string:
Allaire's*Web*Site
Special characters are: + * ? . [ ^ $ ( ) { | \
Any character that is not a special character matches itself.
Use the keyboard (Tab, Enter) to match whitespace characters.
The asterisk (*) matches the specified characters throughout the entire
document.
The carat (^) matches the beginning of the document.
The dollar sign ($) matches the end of the document.
A backslash (\) followed by any special character matches the literal character
itself, that is, the backslash escapes the special character.
A period (.) matches any character, including newline. To match any character
except a newline, use [^#chr(13)##chr(10)#], which excludes the ASCII carriage
return and line feed codes.
A set of characters enclosed in brackets ([]) is a one-character RE that matches
any of the characters in that set. For example, "[akm]" matches an "a", "k", or
"m". Note that if you want to include ] (closing square bracket) in square
brackets it must be the first character. Otherwise, it won't work even if you use
\].
Any regular expression can be followed by one of the following suffixes: {m,n}
forces a match of m through n (inclusive) occurrences of the preceding regular
expression. The suffix {m,} forces a match of at least m occurrences of the
preceding regular expression. The syntax {,n} is not allowed.
A range of characters can be indicated with a dash. For example, "[a-z]"
matches any lowercase letter. However, if the first character of the set is the
caret (^), the RegExp matches any character except those in the set. It does not
match the empty string. For example: [^akm] matches any character except "a",
"k", or "m". The caret loses its special meaning if it is not the first character of
the set.
All regular expressions can be made case insensitive by substituting individual
characters with character sets, for example, [Nn][Ii][Cc][Kk].
