XMLUnit は Java での XML ドキュメントの比較にどのように役立ちますか?

import org.xmlunit.XMLUnit;

// Ignore whitespace differences for more flexible comparison
XMLUnit.setIgnoreWhitespace(true);

// Compare XML as Strings
assertXMLEqual(xmlString1, xmlString2);

// Alternatively, compare with Documents, InputSources, Readers, or Diffs

public class XMLComparisonExample {
  public static void main(String[] args) {
    String xml1 = "<root><child>Node 1</child></root>";
    String xml2 = "<root><child name=\"node1\">Node 1</child></root>";

    // Configure XMLUnit for more lenient comparison
    XMLUnit.setIgnoreWhitespace(true);
    XMLUnit.setIgnoreAttributeOrder(true);

    // Assert the documents are semantically equivalent
    assertXMLEqual(xml1, xml2);  
  }
}
