Regex

The Regex Node in your workflow uses the Regex Extract action. This tool allows you to extract specific patterns or information from a block of text using regular expressions (regex).

Available Actions

Regex Extract

• Purpose: Extracts content from text using a regular expression pattern you provide.

• Provider: Regex

Inputs Required

1. Content (string, required)

   • The text you want to extract information from.

   • Example: "Order number: 12345, Date: 2025-07-10"

2. Expression (string, required)

   • The regular expression pattern to search for in the content.

   • Example: "Order number: (\d+)"

Output

• Result (string)

  • The extracted value(s) from the content that match your regex pattern.

How to Use the Regex Node

1. Connect the node: Pass the text you want to analyze (from an LLM, input, or another node) into the Regex node.

2. Configure the action:

   • Set the "Content" field to the text you want to search.

   • Set the "Expression" field to your desired regex pattern.

3. Use the output: The result will be available as {action-X.result} (where X is the node number) for downstream nodes.

Example Usage

Suppose you want to extract an order number from a message:

• Content: "Order number: 12345, Date: 2025-07-10"

• Expression: "Order number: (\d+)"

• Result: "12345"

You can reference this result in other nodes using {action-3.result} if your Regex node is action-3.
