Regular Expression Library
A regular expression is a special type of computer code that will match, or validate text based on certain syntax rules. If you’re familiar to the way a wildcard search operates (using * to substitute characters etc), then think of a regular expression as a much, much more powerful way of searching and filtering text.
For a comprehensive overview of regular expressions and their use, you can use an internet search engine to search for “regular expressions” and visit one of the many excellent internet resources available on the subject.
HelpMaster contains a short list of useful, common regular expressions however it is possible to create an unlimited number of regular expressions to suit your exact data validation requirements by using the Administration > Regular Expression Library
You can add, remove or edit the regular expressions in this list, and use them for validation for custom fields, or for Email Manager reply separators.
Use
Use the New, Edit, or Delete buttons as required.
Test regular expressions by pasting sample text into the “Test” text box. If the expression fails, the text box will turn red.
Use the “Group Type” drop-down box to classify the type of regular expressions. This will assist in grouping like expressions together. Click on the column headers to sort and group.
Handy tip
Regular expressions can be very tricky to create and get right. Try using AI to create a RegEx for you.
Open Windows CoPilot (or similar service), and type a plain-english expression of what you’re trying to do. For example:
“Create a regex to filter out “gmail”, “hotmail”, “yahoo””
or
“Create a regex to validate an IP address starting with 110.”
