在使用XMLUnit 2.X比较xml文件时忽略特定节点的特定属性

我有两个XML文件:

<!------------------------File1--------------------------------->
    <note id="ignoreThisAttribute_1">
      <to>Experts</to>
      <from>Matrix</from>
      <heading id="dontIgnoreThisAttribute_1">Reminder</heading>
      <body>Help me with this problem</body>
    </note>

<!------------------------File2--------------------------------->
    <note id="ignoreThisAttribute_2">
      <to>Experts</to>
      <from>Matrix</from>
      <heading id="dontIgnoreThisAttribute_2">Reminder</heading>
      <body>Help me with this problem</body>
    </note>

id 节点的数量: note

DiffBuilder :

Diff documentDiff = DiffBuilder.compare(srcFile).withTest(destFile).build()

大多数在线解决方案建议实施 DifferenceEvaluator :

public class IgnoreAttributeDifferenceEvaluator implements DifferenceEvaluator {
        private String attributeName;
        public IgnoreAttributeDifferenceEvaluator(String attributeName) {
            this.attributeName = attributeName;
        }

        @Override
        public ComparisonResult evaluate(Comparison comparison, ComparisonResult outcome) {
            if (outcome == ComparisonResult.EQUAL)
                return outcome;
            final Node controlNode = comparison.getControlDetails().getTarget();


            System.out.println(controlNode.getNodeName());
            if (controlNode instanceof Attr) {
                Attr attr = (Attr) controlNode;
                if (attr.getName().equals(attributeName)) {
                    return ComparisonResult.EQUAL;
                }
            }
            return outcome;
        }
    }

在我的测试类中调用方法:

final Diff documentDiff = DiffBuilder.compare(src).withTest(dest)
.withDifferenceEvaluator(new IgnoreAttributeDifferenceEvaluator("id"))
.build();

XMLUnit新手,请提供相应帮助。

提前谢谢。
