Formula - regexgroup

Easily extract values from messages using the Nodinite regexgroup Formula plugin. This page shows you how to use regular expressions and group identifiers to retrieve data from message content, context values, or results from other formulas for your integrations.

✅ Extract single or multiple values using any valid regular expression group
✅ Use simple expressions to transform message content or context
✅ See clear, real-world examples with input, formula, and result

What does the regexgroup Formula do?

The regexgroup('Expression', groups, Content) Formula function extracts values from text using any valid regular expression and group identifier. You can use this function on message bodies, context values, or results from other formulas.

Example 1: Extracting Groups from Message Body

Input from Body

ID=123,CUSTOMER=1
ID=456,CUSTOMER=2

Formula Expression

regexgroup('ID=(\d+)', '1', body)

Result

123
456

RegEx Group Simple Parameter
Example: Extracting group values from message body using regexgroup

Example 2: Extracting a Group from Message Context

Suppose you have a message context value with the key OrderRecord containing order data.

Input

ORD|101|ExampleCompany1|456|Company Name ACME |Dieselgate valley 1|123 45|Flameburg|

Formula Expression

regexgroup('^(?:(.*?)\|){4}', 1, context('OrderRecord'))

Result

456

RegEx Group Message Context
Example: Extracting a group value from message context using regexgroup

Features

  • Extract single or multiple unique values from any Content using regular expression groups
  • Supports match all, one, or selected groups
  • Works with message body, context, or results from other Formula functions
  • Ensures data integrity across integrated systems

Important

The regexgroup plugin loads the entire message into RAM. Only use this function on small messages to avoid performance issues.

How to use the regexgroup Formula

  1. Select Formula as the expression type plugin.
  2. Enter your regexgroup expression in the 'Expression' text area.
  3. Specify the group(s) to extract (e.g., 1 or 1,4-6).
  4. Provide a string as the Content parameter (e.g., message body, context value, or another formula result).

Syntax

  • Extract from message body:
    regexgroup('Expression', groups, body)
  • Extract from message context:
    regexgroup('Expression', groups, context('MessageContextKey'))
  • Extract from another formula:
    regexgroup('Expression', groups, SomeOtherNestedFormulaFunction(Content))
