Create XML file using java

Solution 1:

You can use a DOM XML parser to create an XML file using Java. A good example can be found on this site:

try {
    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();

    //root elements
    Document doc = docBuilder.newDocument();

    Element rootElement = doc.createElement("company");
    doc.appendChild(rootElement);

    //staff elements
    Element staff = doc.createElement("Staff");
    rootElement.appendChild(staff);

    //set attribute to staff element
    Attr attr = doc.createAttribute("id");
    attr.setValue("1");
    staff.setAttributeNode(attr);

    //shorten way
    //staff.setAttribute("id", "1");

    //firstname elements
    Element firstname = doc.createElement("firstname");
    firstname.appendChild(doc.createTextNode("yong"));
    staff.appendChild(firstname);

    //lastname elements
    Element lastname = doc.createElement("lastname");
    lastname.appendChild(doc.createTextNode("mook kim"));
    staff.appendChild(lastname);

    //nickname elements
    Element nickname = doc.createElement("nickname");
    nickname.appendChild(doc.createTextNode("mkyong"));
    staff.appendChild(nickname);

    //salary elements
    Element salary = doc.createElement("salary");
    salary.appendChild(doc.createTextNode("100000"));
    staff.appendChild(salary);

    //write the content into xml file
    TransformerFactory transformerFactory =  TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);

    StreamResult result =  new StreamResult(new File("C:\\testing.xml"));
    transformer.transform(source, result);

    System.out.println("Done");

}catch(ParserConfigurationException pce){
    pce.printStackTrace();
}catch(TransformerException tfe){
    tfe.printStackTrace();
}

You can use Xembly, a small open source library that makes this XML creating process much more intuitive:

String xml = new Xembler(
  new Directives()
    .add("root")
    .add("order")
    .attr("id", "553")
    .set("$140.00")
).xml();

Xembly is a wrapper around native Java DOM, and is a very lightweight library.

Have look at dom4j or jdom. Both libraries allow creating a Document and allow printing the document as xml. Both are widly used, pretty easy to use and you'll find a lot of examples and snippets.

Just happened to work at this also, use https://www.tutorialspoint.com/java_xml/java_dom_create_document.htm the example from here, and read the explanations. Also I provide you my own example:

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.newDocument();
        // root element


Element rootElement = doc.createElement("words");
            doc.appendChild(rootElement);
while (ptbt.hasNext()) {
                CoreLabel label = ptbt.next();
                System.out.println(label);

                m = r1.matcher(label.toString());
                //System.out.println(m.find());
                if (m.find() == true) {
                    Element w = doc.createElement("word");                  
                    w.appendChild(doc.createTextNode(label.toString()));
                    rootElement.appendChild(w);
                }

TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        DOMSource source = new DOMSource(doc);
        StreamResult result = new StreamResult(new File("C:\\Users\\workspace\\Tokenizer\\tokens.xml"));
        transformer.transform(source, result);
        // Output to console for testing
        StreamResult consoleResult = new StreamResult(System.out);
        transformer.transform(source, consoleResult);

This is in the context of using the tokenizer from Stanford for Natural Language Processing, just a part of it to make an idea on how to add elements. The output is: Billbuyedapples (I've read the sentence from a file)
