如何比较两个xml 的异同

http://www.xmlunit.org/

<dependency>
    <groupId>org.xmlunit</groupId>
    <artifactId>xmlunit-core</artifactId>
    <version>2.3.0</version>
</dependency>

<root>
    <id>123</id>
    <name>liming</name>
</root>

<root>
    <id>1234</id>
    <name>liming</name>
</root>

import static org.junit.Assert.assertFalse;

import java.io.File;

import javax.xml.transform.Source;

import org.junit.Test;
import org.xmlunit.builder.DiffBuilder;
import org.xmlunit.builder.Input;
import org.xmlunit.diff.Diff;
import org.xmlunit.diff.Difference;

public class Xmltest {

    @Test
    public void ff() {
        File control = new File("E://control.xml");
        File test = new File("E://test.xml");
        
        Source sourceControl = Input.fromFile(control).build();
        Source sourceTest = Input.fromFile(test).build();
        
        Diff build = DiffBuilder.compare(sourceControl).withTest(sourceTest).ignoreComments().ignoreWhitespace().build();
        
        boolean hasDifferences = build.hasDifferences();
        if (hasDifferences) {
            Iterable<Difference> differences = build.getDifferences();
            for (Difference difference : differences) {
                System.out.println(difference);
            }
        }
        assertFalse(hasDifferences);
    }

}

运行结果：

Expected text value '123' but was '1234' - comparing <id ...>123</id> at /root[1]/id[1]/text()[1] to <id ...>1234</id> at /root[1]/id[1]/text()[1] (DIFFERENT)
