Convert an org.w3c.dom.Node into a String
提问by ragebiswas
Sorry I'm a Java/XML newbie - and can't seem to figure this one out. It seems it's possible to convert a Document object to a string. However, I want to convert a Node object into a string. I am using org.ccil.cowan.tagsoup Parser for my purpose.
抱歉，我是 Java/XML 新手 - 似乎无法弄清楚这一点。似乎可以将 Document 对象转换为字符串。但是，我想将 Node 对象转换为字符串。我正在使用 org.ccil.cowan.tagsoup Parser 来达到我的目的。
I'm retrieving the Node by something like...
我正在通过以下方式检索节点...
parser = new org.ccil.cowan.tagsoup.Parser()
parser.setFeature(namespaceaware, false)
Transformer transformer = TransformerFactory.newInstance().newTransformer();
DOMResult domResult = new DOMResult();
transformer.transform(new SAXSource(parser, new InputSource(in)), domResult);
Node n = domResult.getNode();
// I'm interested in the first child, so...
Node myNode = n.getChildNodes().item(0);
// convert myNode to string..
// what to do here?
The answer may be obvious, but I can't seem to figure out from the core Java libraries how to achieve this. Any help is much appreciated!
答案可能很明显，但我似乎无法从核心 Java 库中找出如何实现这一点。任何帮助深表感谢！

You can use a Transformer(error handling and optional factory configuration omitted for clarity):
您可以使用Transformer（为清楚起见，省略了错误处理和可选的工厂配置）：
Node node = ...;
StringWriter writer = new StringWriter();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(node), new StreamResult(writer));
String xml = writer.toString();
// Use xml ...

String getNodeString(Node node) {
try {
StringWriter writer = new StringWriter();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(node), new StreamResult(writer));
String output = writer.toString();
return output.substring(output.indexOf("?>") + 2);//remove <?xml version="1.0" encoding="UTF-8"?>
} catch (TransformerException e) {
e.printStackTrace();
}
return node.getTextContent();
}

This is way to convert Node to html
这是将 Node 转换为 html 的方法
public static String getInnerHTML(Node node) throws TransformerConfigurationException, TransformerException
{
StringWriter sw = new StringWriter();
Result result = new StreamResult(sw);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer proc = factory.newTransformer();
proc.setOutputProperty(OutputKeys.METHOD, "html");
for (int i = 0; i < node.getChildNodes().getLength(); i++)
{
proc.transform(new DOMSource(node.getChildNodes().item(i)), result);
}
return sw.toString();
}
