Question

I am creating a XML using DOM as below using online examples,

DocumentBuilderFactory docfac= DocumentBuilderFactory.newInstance();
    DocumentBuilder docb= docFactory.newDocumentBuilder();

    Document doc = docb.newDocument();

    // root
    Element rootElement = (Element)doc.createElement("TEST");

    doc.appendChild(rootElement); //Compiler error
...

appenchild takes Node object, not Element object. I was trying to use Node but, it seems like there is no methods exposed to set attribute, therefore, I can’t really use node.

Any help would be really appreciate it.

Thanks.

Please verify the packages you’ve imported : import org.w3c.dom.Document and import org.w3c.dom.Element; and change docfac.newDocumentBuilder();

No need to type cast the org.w3c.dom.Element because doc.createElement("TEST") returns an object of org.w3c.dom.Element which is a sub-interface of org.w3c.dom.Node.

org.w3c.dom.Element rootElement = doc.createElement("TEST");
doc.appendChild(rootElement)
