Examining the DOMExample Class

DOMExample first creates a DOM document by parsing an XML document. The file it parses is one that you specify on the command line.

static Document document;
...
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    try {
        DocumentBuilder builder = factory.newDocumentBuilder();
        document = builder.parse( new File(args[0]) );
        ...

Next, the example creates a SOAP message in the usual way. Then it adds the document to the message body:

        SOAPBodyElement docElement = body.addDocument(document);

This example does not change the content of the message. Instead, it displays the message content and then uses a recursive method, getContents, to traverse the element tree using SAAJ APIs and display the message contents in a readable form.

public void getContents(Iterator iterator, String indent) {

    while (iterator.hasNext()) {
        Node node = (Node) iterator.next();
        SOAPElement element = null;
        Text text = null;
        if (node instanceof SOAPElement) {
            element = (SOAPElement)node;
            QName name = element.getElementQName();
            System.out.println(indent + "Name is " + name.toString());
            Iterator attrs = element.getAllAttributesAsQNames();
            while (attrs.hasNext()){
                QName attrName = (QName)attrs.next();
                System.out.println(indent + " Attribute name is " +
                     attrName.toString());
                System.out.println(indent + " Attribute value is " +
                     element.getAttributeValue(attrName));
            }
            Iterator iter2 = element.getChildElements();
            getContents(iter2, indent + " ");
        } else {
            text = (Text) node;
            String content = text.getValue();
            System.out.println(indent + "Content is: " + content);
            }
        }
    }
