Use if_else_node for conditional execution based on runtime conditions—handling different page states, optional elements, or branching logic.

Properties
| Property | Type | Description |
|---|
condition | str | Python-like expression to evaluate |
if_nodes | list[action_node | if_else_node | for_loop_node] | Actions when condition is true |
else_nodes | list[...] | Actions when condition is false (optional) |
Condition Syntax
Conditions are Python-like expressions that can reference parameters:
{
"condition": "is_login_screen[0]"
}
{
"condition": "has_2fa[0] == 'true'"
}
{
"condition": "verification_needed[0] is not None and verification_needed[0] != 'skip'"
}
Operators
| Operator | Example |
|---|
| Equality | var[0] == 'value' |
| Inequality | var[0] != 'value' |
| None check | var[0] is not None |
| Boolean | var[0] == 'true' |
| Logical AND | a[0] == 'x' and b[0] == 'y' |
| Logical OR | a[0] == 'x' or b[0] == 'y' |
Examples
Handle Optional 2FA
{
"type": "if_else_node",
"condition": "requires_2fa[0] == 'true'",
"if_nodes": [
{
"type": "action_node",
"interaction_action": {
"input_text": {
"command": "get_by_label(\"Verification Code\")",
"input_text": "{auth_code[0]}"
}
}
}
],
"else_nodes": []
}
[
{
"type": "action_node",
"extraction_action": {
"llm": {
"extraction_format": { "status": "str" },
"extraction_instructions": "Extract the order status",
"output_variable_names": ["status"]
}
}
},
{
"type": "if_else_node",
"condition": "status[0] == 'pending'",
"if_nodes": [
{
"type": "action_node",
"interaction_action": {
"click_element": {
"command": "get_by_role(\"button\", name=\"Approve\")"
}
}
}
],
"else_nodes": []
}
]
Nested Conditions
{
"type": "if_else_node",
"condition": "user_type[0] == 'admin'",
"if_nodes": [
{
"type": "if_else_node",
"condition": "access_level[0] == 'full'",
"if_nodes": [ ... ],
"else_nodes": [ ... ]
}
],
"else_nodes": []
}
else_nodes is optional. If omitted or empty, nothing happens when condition is false.
