DiffConfig

java.lang.Object
- eu.maveniverse.domtrip.DiffConfig

```
public class DiffConfig
extends java.lang.Object
```
Configuration for XML diff operations.
Controls how elements are matched between two documents. By default, elements are matched positionally among same-name siblings. Configuring match keys enables identity-based matching for domain-specific element types.

Example:
```
 DiffConfig config = DiffConfig.builder()
     .matchBy("dependency", "groupId", "artifactId")
     .matchBy("*", "id")
     .build();
 
```
Since:

1.3.0
