Hi,

When I am trying to replace the existing XML tag with other one I am getting the following exception:

org.w3c.dom.DOMException: NOT_FOUND_ERR: An attempt is made to reference a node in a context where it does not exist.

The following is the code I am using :

public void replaceNode() throws Exception{
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse("file:/C:/Documents and Settings/srikanth.d.KNOAHSOFT/Desktop/Linechart.jrxml");
        Element root = doc.getDocumentElement();
        Element newElement = doc.createElement("stackedBarchart");
        
        NodeList oldList = root.getElementsByTagName("lineChart");

        int length = oldList.getLength();
        System.out.println("length::"+length);
        for(int i=0;i<length;i++)
        {
            Node oldNode = oldList.item(i);
            NodeList nl = doc.getChildNodes();
            
newElement.getTagName().toString());                    
(i).getNodeName().toString());
            doc.replaceChild((Node)newElement, oldNode);            
        }
    }

Can anybody help me in this regard...

Thanks and Regards
