Regular expression

Regular expressions in rules for processing emails allow you to isolate a desired fragment of text when extracting data from an email.

Important

• The use of regular expressions typically requires programming skills. If you don't know any programming languages, you should ask for help.
• In Planfix, regular expressions operate with the Pattern.DOTALL and Pattern.MULTILINE options. For validation, you can use the validator — gms
• Regular expressions can also be used with the REGEXPFIND Function.

Formatting regular expressions

Planfix uses the regular expression format used in Java. The syntax of regular expressions uses the symbols <([{\^-=$!|]})?*+.>, which can be combined with letters to create metacharacters. The most frequently used metacharacters are listed in this table:

Metacharacter	Meaning
^	beginning of input
$	end of input
\d	digit
\D	non-digit character
\s	space character
\S	non-space character
\w	alphanumeric character or underscore
\W	any character except alphanumerics and underscores
.	any character
\t	tab character
\n	newline symbol
\r	carriage return symbol
[abc]	any of the characters listed (a, b, or c)
[^abc]	any character except those listed (not a, b, or c)
[a-zA-Z]	multiple ranges (Latin characters from A to Z, case-insensitive)
[a-d[m-p]]	combining characters (from a to d and from m to p)
[a-z&&[def]]	overlapping characters (d, e, f)
[a-z&&[^bc]]	subtracting characters (a, d-z)
?	one or not exist
*	match zero or one
+	one or more times
{n}	n times
{n,}	n or more times
{n,m}	at least n times and no more than m times

Helpful information

• The result of text processing using a regular expression becomes the first capturing group. Accordingly, what is needed in the result should be enclosed in parentheses, and the rest of the groups should be made non-capturing (?:)
