将org.w3c.dom.Document打印到stdout的最短路径是什么？

Question

什么是将org.w3c.dom.Documentstdout 打印(也称为格式化)a的最简单方法？

Answer 1

调用printDocument(doc, System.out),该方法如下所示:

public static void printDocument(Document doc, OutputStream out) throws IOException, TransformerException {
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");

    transformer.transform(new DOMSource(doc), 
         new StreamResult(new OutputStreamWriter(out, "UTF-8")));
}

(这indent-amount是可选的,可能不适用于您的特定配置)

Answer 2

怎么样:

OutputFormat format = new OutputFormat(doc);
format.setIndenting(true);
XMLSerializer serializer = new XMLSerializer(System.out, format);
serializer.serialize(doc);

Answer 3

尝试使用一个衬垫jcabi-xml:

String xml = new XMLDocument(document).toString();

这是您需要的依赖:

<dependency>
  <groupId>com.jcabi</groupId>
  <artifactId>jcabi-xml</artifactId>
  <version>0.14</version>
</dependency>
