    Transformer transformer = tf.newTransformer();
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

    StringWriter writer = new StringWriter();
    transformer.transform(new DOMSource(doc), new StreamResult(writer));
    return writer.toString();
}

import xml.dom.minidom

return dom.toprettyxml(indent="  ")</p><h1>示例调用</h1><p>raw_xml = '<root><child name="test">value</child></root>'
print(format_xml(raw_xml))</p>
