如何在xmlunit中比较有前缀和无前缀xml文档以获得相似的结果

import org.xmlunit.builder.DiffBuilder;
import org.xmlunit.diff.Diff;
import org.xmlunit.diff.Difference;

public class XmlComparison {
    public static void main(String[] args) {
        // 创建有前缀的XML文档对象
        String xmlWithPrefix = "<ns:root xmlns:ns='http://example.com'><ns:child>Value</ns:child></ns:root>";
        org.w3c.dom.Document docWithPrefix = org.xmlunit.util.Convert.toDocument(xmlWithPrefix);

        // 创建无前缀的XML文档对象
        String xmlWithoutPrefix = "<root><child>Value</child></root>";
        org.w3c.dom.Document docWithoutPrefix = org.xmlunit.util.Convert.toDocument(xmlWithoutPrefix);

        // 配置前缀策略
        org.xmlunit.util.PreferredPrefixPrefixMatcher matcher = new org.xmlunit.util.PreferredPrefixPrefixMatcher();
        matcher.addNamespace("http://example.com", "ns");

        // 比较XML文档
        Diff diff = DiffBuilder.compare(docWithPrefix)
                .withTest(docWithoutPrefix)
                .withNodeMatcher(new org.xmlunit.util.NodesHavingSameLocalNameAndNamespaceMatcher(matcher))
                .checkForSimilar()
                .build();

        // 输出差异结果
        for (Difference difference : diff.getDifferences()) {
            System.out.println(difference);
        }
    }
}
