Conditional Branch IF/ELSE

Definition

Allows you to split the workflow into two branches based on if/else conditions.

A conditional branching node has three parts:

• IF Condition: Select a variable, set the condition, and specify the value that satisfies the condition.

• IF condition evaluates to True, execute the IF path.

• IF condition evaluates to False, execute the ELSE path.

• If the ELIF condition evaluates to True, execute the ELIF path;

• If the ELIF condition evaluates to False, continue to evaluate the next ELIF path or execute the final ELSE path.

Condition Types

• Contains

• Not contains

• Starts with

• Ends with

• Is

• Is not

• Is empty

• Is not empty

Scenario

Taking the above Text Summary Workflow as an example:

• IF Condition: Select the summarystyle variable from the start node, with the condition Contains technical.

• IF condition evaluates to True, follow the IF path by querying technology-related knowledge through the knowledge retrieval node, then respond via the LLM node (as shown in the upper half of the diagram);

• IF condition evaluates to False, but an ELIF condition is added, where the input for the summarystyle variable does not include technology, yet the ELIF condition includes science, check if the condition in ELIF is True, then execute the steps defined within that path;

• If the condition within ELIF is False, meaning the input variable contains neither technology nor science, continue to evaluate the next ELIF condition or execute the final ELSE path;

• IF condition evaluates to False, i.e., the summarystyle variable input does not contain technical, execute the ELSE path, responding via the LLM2 node (lower part of the diagram).

Multiple Condition Judgments

For complex condition judgments, you can set multiple condition judgments and configure AND or OR between conditions to take the intersection or union of the conditions, respectively.
