XML 文档到字符串 [英] XML Document to String

问题描述

获取 XML 文档 (org.w3c.dom.Document) 的字符串表示形式的最简单方法是什么?也就是说，所有节点都在一行上.

What's the simplest way to get the String representation of a XML Document (org.w3c.dom.Document)? That is all nodes will be on a single line.

举个例子，来自

<root>
  <a>trge</a>
  <b>156</b>
</root>

(这只是一个树表示，在我的代码中它是一个 org.w3c.dom.Document 对象，所以我不能把它当作一个字符串)

(this is only a tree representation, in my code it's a org.w3c.dom.Document object, so I can't treat it as a String)

到

"<root> <a>trge</a> <b>156</b> </root>"

谢谢！

推荐答案

假设 doc 是您的 org.w3c.dom.Document 实例:

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("
|
", "");
