Combines two conditions and matches only when *exactly one* of them is satisfied. If both match, or neither matches, the rule fails. Use this when two situations should never be true at the same time, for example flagging a price that is either unusually high *or* unusually low, but treating a normal price as neither.

This documentation describes: [Schema](/schemas/condition/logic-xor)

## Fields

<FormField property="left" label="Left condition" required diType="condition">
  The first of the two checks to compare. You pick and configure any condition here, such as a number comparison or an equality check.
</FormField>

<FormField property="right" label="Right condition" required diType="condition">
  The second of the two checks to compare. The rule matches only when this check and the left check disagree: one matches and the other does not. When both match, or both fail, the rule fails.
</FormField>

## Sample data

This rule compares two checks on an order's `price`: greater than 100 on the left, less than 10 on the right. A price matches when exactly one side is true. A mid-range price triggers neither side, so it does not match. (A price cannot be both above 100 and below 10, so the "both true" case never arises here; if it ever did, the rule would not match.)

| Field           | Value                     |
| --------------- | ------------------------- |
| Left condition  | Number greater than `100` |
| Right condition | Number less than `10`     |

| Price | Greater than 100? | Less than 10? | Matches? |
| ----- | ----------------- | ------------- | -------- |
| `250` | yes               | no            | yes      |
| `5`   | no                | yes           | yes      |
| `50`  | no                | no            | no       |
