    Default Parsing XML

    I'm trying to parse an XML file into an XML file. So basically I'm appending some static elements, attributes, and Text Content for the most part, but I have about 16 dynamic TextContent fields that I want to parse from an existing XML document into my new one. The way I want to do it is to use a for statement the nodes to iterate through to pull the information. I'm getting an implementation error on the for statements and I'm not sure how else to do this without a for statement. Any ideas? Thanks. Here's the relevant code so far:

    public static void main(String[] args) {
     
            try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder loader = factory.newDocumentBuilder();
     
          Document input = loader.parse(new FileInputStream("c:\\XML\\input.xml"));
     
            Node Order = input.getDocumentElement();
     
            NodeList DetailsList = input.getElementsByTagName("Details");
     
            for (Node Detail : DetailsList) { 
     
            DocumentBuilder docBuilder = factory.newDocumentBuilder();
     
            Document doc = docBuilder.newDocument();
     
            Element root = doc.createElement("MercuryGate");
            doc.appendChild(root);
     
    //...Various create element and append statements follow
     
    NodeList FieldsList = input.getElementsByTagName("Field");
     
            for (Node Field : FieldsList){
     
    //...My for statements that pull the content and then insert it into the setTextContent fields where necessary in my previous code
     
        TransformerFactory tranFactory = TransformerFactory.newInstance();
        Transformer aTransformer = tranFactory.newTransformer();
     
        Source src = new DOMSource(doc);
        Result dest = new StreamResult("c:\\XML\\xmltest.xml");
        aTransformer.transform(src, dest);  
     
     
                }
        }
     
        catch(Exception e){
          System.out.println(e.getMessage());
        }

    Default Re: Parsing XML

    You need to provide the XML document you are attempting to parse and also show the desired output.
    We can take it from there..
