Dom4j生成XML document to String

此前苦苦寻找的方法:

 

1         java.io.StringWriter out = new java.io.StringWriter();
2         XMLWriter xw = new XMLWriter (out, new OutputFormat (" ", true, "GB2312"));
3         xw.write(document);
4         String xmlstring = out.toString();
5         return xmlstring;
