在XMLUnit

Question

我想修改XMLUnit中的DifferenceListener，以便在比较XML文件时忽略属性id。我尝试使用以下内容进行此操作。

import org.custommonkey.xmlunit.DifferenceListener;
import org.custommonkey.xmlunit.Difference;
import org.custommonkey.xmlunit.DifferenceConstants;

public class ignoreIDs implements DifferenceListener {

    private static final int[] IGNORE_VALUES = new int[] {
        DifferenceConstants.ATTR_VALUE.getId(),
    };

    private boolean isIgnoredDifference(Difference diff) {
        int DiffId = diff.getId();
        for (int value: IGNORE_VALUES) {
            if (DiffId == value) return true;
        }
        return false;
    }

    public int differenceFound(Difference difference) {
        if (isIgnoredDifference(difference)) return RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL;
        else return RETURN_ACCEPT_DIFFERENCE;
    }
    public void skippedComparison() {

    }


}

但是我无法理解如何只在IGNORE_VALUES数组中输入id属性。请帮帮我。
