  1. POHaving problems reading an XML file in Java and getting Element attributes
    text
    copied!<p>My objective is to read an XML file and provide a simple interface that will enable a (non-technical) user to modify this file. The xml file drives a Flash photo gallery and is pre-defined by that Flash Actionscript.</p> <p>A sample of the XML is</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt; &lt;photostack3d&gt; &lt;photos&gt; &lt;photo&gt; &lt;thumb src="Thumbs/bed1.jpg"/&gt; &lt;img src="Photos/bed1.jpg"/&gt; &lt;caption text="Master Bedroom"/&gt; &lt;desc&gt;&lt;![CDATA[&lt;h1&gt;Master Bedroom&lt;/h1&gt;&lt;br&gt;The master bedroom is roomy and has a beautiful view of the landscaped back yard.]]&gt;&lt;/desc&gt; &lt;/photo&gt; &lt;/photos&gt; &lt;/photostack3d&gt; </code></pre> <p>In this XML, there can be multiple photo nodes, since those define each of the photos that will be displayed by the gallery...</p> <p>Now, I'm at the point where I am using DOM to create the file, so we're good there. Using DOM to try and read it in for further editing is where I'm running into a problem. I can get to all of the photo elements, but I'm having a problem getting at the attributes in there, namely thumb, img, caption and desc. Currently, I have the following:</p> <pre class="lang-java prettyprint-override"><code>private void loadXML(String filePath) { try { File fXmlFile = new File(filePath); DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); Document doc = dBuilder.parse(fXmlFile); doc.getDocumentElement().normalize(); System.out.println("Root element :" + doc.getDocumentElement().getNodeName()); NodeList photosList = doc.getElementsByTagName("photos"); System.out.println("-----------------------"); NodeList photoList = doc.getElementsByTagName("photo"); System.out.println("Number of photo nodes: " + photoList.getLength()); for (int temp = 0; temp &lt; photoList.getLength(); temp++) { NodeList thumbList = doc.getElementsByTagName("thumb"); Element thumbElement = (Element) thumbList.item(0); String thumbName = thumbElement.getAttribute("thumb"); System.out.println("thumb name: " + thumbName); //Node nNode = photoList.item(temp); //if (nNode.getNodeType() == Node.ELEMENT_NODE) //{ // Element eElement = (Element) nNode; // System.out.println("Source Name : " + eElement.getAttribute("text")); //.getElementsByTagName("thumb")); //System.out.println("Source Name : " + getTagValue("thumb", eElement)); System.out.println("-----------------------"); //} } } catch (Exception e) { e.printStackTrace(); } } </code></pre> <p>As you can see, I've been trying various different way to get at those attributes, but as of yet, just don't see the values coming back. Where am I going wrong?</p>
