Java get Attributes with DOM Reader

Hey I'd like to get attributes of a Feed.

This is my actual code: 

DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
    try {
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();

            Document document = documentBuilder.parse(this.getUrlStream());
            document.getDocumentElement().normalize();
            NodeList nodeList = document.getElementsByTagName("item");

            for (int i = 0; i <= nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                System.out.println("Node name: " + node.getNodeName());
                Element element1 = (Element) node;
                System.out.println("title; " + element1.getElementsByTagName("title").item(0).getTextContent());
                Element element = (Element) node;
                if(node.getNodeType() == Node.ELEMENT_NODE) {


                    this.title = element.getElementsByTagName("title").item(0).getTextContent();




                    System.out.println("description" + element.getElementsByTagName("description").item(0).getTextContent());

                    String attribute = element.getAttribute("src");
                    System.out.println(attribute);
                }

            }


    } catch (ParserConfigurationException | SAXException | IOException ex) {
        ex.printStackTrace();
    }

The following part of the code above should find the attribute: "url":

String attribute = element.getAttribute("src");
                    System.out.println(attribute);

Sysout: Nothing

You are using getAttribute() on the Element object of the <item> tag. However you have to select the <enclosure> tag first by using the getElementsByTagName() as you already did. So you have to use something like:

for (...) {
   // ...

   // "element" is the object for the <item> tag
   Element enclosure = (Element)element.getElementsByTagName("enclosure").item(0);
   String url = enclosure.getAttribute("url");
}
