DOM to XML String

Question

Hi,
I'm trying to transform a DOM object into a string of xml, but somehow it only outputs the first line.
What did I do wrong?
          Document doc = processDoc();
          Source source = new DOMSource((Element) doc.getElementsByTagName("vancouver").item(0));
          StringWriter out = new StringWriter();
          StreamResult result = new StreamResult(out);
          Transformer xformer = TransformerFactory.newInstance().newTransformer();
          xformer.setOutputProperty("encoding", "iso-8859-1");
          xformer.setOutputProperty("indent", "yes");
          xformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
          xformer.transform(source, result);
          return result.getWriter().toString();Thanks!

Hi DrClap,
this is how I constructed my DOM object:
     public Document processDoc() throws Exception {
          URL u = new URL("http://www.weatheroffice.ec.gc.ca:80/city/pages/bc-74_metric_e.html");
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder = factory.newDocumentBuilder();
          // in doc
          Document inDoc = builder.parse(u.openStream());
          // out doc
          Document outDoc = builder.newDocument();
          // grab <div id="citytextf">
          Element inElement = inDoc.getElementById("citytextf");
          Element rootElement = inElement;
          // grab <h2>
          inElement = (Element) inElement.getElementsByTagName("h3").item(0);
          System.out.println(inElement.getTextContent());
          // create output root element
          Element outElement = outDoc.createElement("vancouver");
          outElement.setAttribute("issued", inElement.getTextContent().substring(11));
          rootElement = (Element) rootElement.getElementsByTagName("dl").item(0);
          // iterate thru city <dd>, <dt> tags
          NodeList tempList = rootElement.getElementsByTagName("dt");
          Element tempIn, tempOut;
          for (int i = 0; i < tempList.getLength(); i++) {
               System.out.println(i);
               tempIn = (Element) rootElement.getElementsByTagName("dt").item(i);     // grabs <dt> value
               tempOut = outDoc.createElement("day");
               tempOut.setAttribute("name", tempIn.getTextContent().trim());
               tempIn = (Element) rootElement.getElementsByTagName("dd").item(i);
               String input = tempIn.getTextContent();
               (tempOut.appendChild(outDoc.createElement("high"))).setNodeValue(getHighLowValue("High", input));
               (tempOut.appendChild(outDoc.createElement("low"))).setNodeValue(getHighLowValue("Low", input));
               (tempOut.appendChild(outDoc.createElement("note"))).setNodeValue(getNoteValue(input));
               System.out.println(((Element) tempOut).getAttribute("name"));
               outElement.appendChild(tempOut);
          return outDoc;
     }which is suppose to output XML like this:
<vancouver issued="Issued 6.30 PM PDT Saturday 16 April 2005">
  <day name="Tonight">
    <high></high>
    <low>6</low>
    <note>Cloudy. 60 percent chance of showers. Risk of small hail this evening.</note>
  </day>
  <day name="Sunday">
    <high>12</high>
    <low></low>
    <note>A few showers.</note>
  </day>
  <day name="Monday">
    <high>13</high>
    <low>6</low>
    <note>A mix of sun and cloud.</note>
  </day>
  <day name="Tuesday">
    <high>13</high>
    <low>6</low>
    <note>Sunny</note>
  </day>
  <day name="Wednesday">
    <high>15</high>
    <low>7</low>
    <note>Sunny</note>
  </day>
</vancouver>
      But all it outputs is:
<?xml version="1.0" encoding="iso-8859-1"?>I just started learning XML in Java so there're probably things that I missed out on.
Thanks!
