我可以找到两个 xml 文件之间的区别，这里是代码

测试XML1.xml

<Root>
    <RName>jj</RName>
    <RID>55</RID>
    <Source>
        <Code ID="17">
           <Target Name="A">
               <Seq name="A_17_Sql" count="10" >
               </Seq>
           </Target>

        </Code>
    </Source>
</Root>

测试XML2.xml

<Root>
    <RName>jj</RName>
    <RID>55</RID>
    <Source>
        <Code ID="17">
           <Target Name="A">
               <Seq name="A_17_Sql" count="9" >
               </Seq>
           </Target>

        </Code>
    </Source>
</Root>

Java代码：

import org.custommonkey.xmlunit.DetailedDiff;
import org.custommonkey.xmlunit.Diff;
import org.custommonkey.xmlunit.Difference;
import org.custommonkey.xmlunit.XMLUnit;
import org.xml.sax.SAXException;
 // reading two xml file to compare in Java program
        FileInputStream fis1 = new FileInputStream("TestXML1.xml");
        FileInputStream fis2 = new FileInputStream("TestXML2.xml");
     
        // using BufferedReader for improved performance
        BufferedReader  source = new BufferedReader(new InputStreamReader(fis1));
        BufferedReader  target = new BufferedReader(new InputStreamReader(fis2));
     
        //configuring XMLUnit to ignore white spaces
        XMLUnit.setIgnoreWhitespace(true);
        
        //comparing two XML using XMLUnit in Java
        List differences = compareXML(source, target);
     
        //showing differences found in two xml files
        printDifferences(differences);
   
    }    
 
    public static List compareXML(Reader source, Reader target) throws
                  SAXException, IOException{
     
        //creating Diff instance to compare two XML files
        Diff xmlDiff = new Diff(source, target);
     
        //for getting detailed differences between two xml files
        DetailedDiff detailXmlDiff = new DetailedDiff(xmlDiff);
     
        return detailXmlDiff.getAllDifferences();
    }
 
    public static void printDifferences(List<Difference> differences){
        int totalDifferences = differences.size();
        System.out.println("===============================");
        System.out.println("Total differences : " + totalDifferences);
        System.out.println("================================");
     
        for(Difference difference : differences){
            System.out.println(difference.getControlNodeDetail().getXpathLocation());
            System.out.println(difference);
        }
    }

输出 ：

===============================
Total differences : 1
================================
/Root[1]/Source[1]/Code[1]/Target[1]/Seq[1]/@count
Expected attribute value '10' but was '9' - comparing <Seq count="10"...> at /Root[1]/Source[1]/Code[1]/Target[1]/Seq[1]/@count to <Seq count="9"...> at /Root[1]/Source[1]/Code[1]/Target[1]/Seq[1]/@count

这种比较工作正常，但我需要显示 attr 名称而不是索引值，如下所示，

===============================
Total differences : 1
================================
/Root[1]/Source[1]/Code[ID=17]/Target[Name=A]/Seq[1]/@count
Expected attribute value '10' but was '9' - comparing <Seq count="10"...> at /Root[1]/Source[1]/Code[ID=17]/Target[Name=A]/Seq[1]/@count to <Seq count="9"...> at /Root[1]/Source[1]/Code[ID=17]/Target[Name=A]/Seq[1]/@count

我们可以像上面那样使用 XMLUnit 吗？
