在不使用转换或XMLSerializer的情况下，将文档（XML）直接转换为Java中的字符串

Question

Is there another way to convert XML Document object to String just like using transform or XmlSerializer from Apache API? I don't want to use mentioned conversion methods because it renders my output xml modifying tags representation ( like collapsing the empty tags to singleton tags). I want conversion method that output in String from the Document object (kind of treating content of Document object as text).

You could do worse than SAX, by extending DefaultHandler2 or DefaultHandler :

class Parser extends DefaultHandler { 
    StringBuffer sb = new StringBuffer();
    public void characters(char[] ch, int start, int length) {
        sb.append(new String(ch, start, length);
    }

    public void startElement(String ns, String qname, String name, Attributes attrs) {
        sb.append(qname+": ");
    }

    public void endElement(String ns, String qname, String name) {
        sb.append("\n");
    }

    public String toString() {
        return sb.toString();
    }
}
