Sorry I'm a Java/XML newbie - and can't seem to figure this one out. It seems it's po开发者_C百科ssible 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.
I'm retrieving the Node by something like...
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!
You can use a Transformer (error handling and optional factory configuration omitted for clarity):
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
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();
}
