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 Containstechnical
.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 anELIF
condition is added, where the input for thesummarystyle
variable does not includetechnology
, yet theELIF
condition includesscience
, check if the condition inELIF
isTrue
, then execute the steps defined within that path;If the condition within
ELIF
isFalse
, meaning the input variable contains neithertechnology
norscience
, continue to evaluate the nextELIF
condition or execute the finalELSE
path;IF condition evaluates to
False
, i.e., thesummarystyle
variable input does not containtechnical
, 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.
