element name and cdata

[James Howerton]

Could someone tell me what has to be changed to get the element name and text of my targetElement?

I just get

internal frame openFrameCount= 1
start obj() type= guide
cmaj
name: null value: null
name: null value: null
name: null value: null
cmaj
name: null value: null
name: null value: null
name: null value: null

Since you dont show the actual XML I can only guess that the Element has multiple Text nodes created by formatting.

Careful study of the marvelous table in the org.w3c.dom.Node JavaDocs is recommended.

Also please use code formatting as much as possible.

[James Howerton]

Well I got the siblings I need but need a good method to produce the text node. Is there a standard method for this?

    public Element r;


    public XMLReaderProgressions() {
    }

    public void readAll(String name) {
        Main m =new Main();
        Document doc= m.readXML(xmlName);
        parseDocument(name,doc);

    }

    public void parseDocument(String name,Document doc) {
        System.out.println(name);
        Element root = doc.getDocumentElement();
        NodeList nl = root.getElementsByTagName("keyname");
        if (nl != null && nl.getLength() > 0) {
            for (int i = 0; i < nl.getLength(); i++) {
                Element e = (Element) nl.item(i);
                String attr = e.getAttribute("key");
                if (attr.equals(name)) {
                    
                    Element r =doc.getElementById(name);
                    System.out.println("desired element: "+r.getNodeName()+" "+attr);
                    t=(Element)r.getNextSibling();
                    
                    //System.out.println("first sibling : "+t.getNodeName());
                    while(t!=null){
                        String pString=getTextValue(t).trim();
                         t=(Element)t.getNextSibling();
                         if(t!=null){
                             

                        System.out.println(" "+t.getNodeName());
                         System.out.println(" "+pString);
                         System.out.println(" "+t.getNodeName());
                         }
                    }
                    
                }
            }

Well, again, we don't see any XML to base an answer on. And your code is not particularly readable -- it would help if you posted it inside the Code tags, so it came out formatted.

But I'm going to assume that this "text node" you're referring to is probably the child node of the element you found. If indeed you did find an element.
