Get an attribute of a dom node
I am trying to get an attribute of an xml node example:
<Car name="Test">
</Car>
I want to grab the name attribute of the car node.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(configFile);
doc.getDocumentElement().normalize();
NodeList layerConfigList = doc.getElementsByTagName("CAR");
Node node = layerConfigList.item(0);
// get the name attribute out of the node.
this is where i get stuck because the only method that looks like i can use is getAttributes() with returns a NamedNodeMap and im not sure how to extract it from that.
Solution 1:
Your node is an Element so you just have to
Element e = (Element)node;
String name = e.getAttribute("name");
Solution 2:
you can do it without using elements, like this:
//HtmlTag represents any arbitrary node that you are trying to get its "car" attribute
if("HtmlTag".equals(node.getNodeName()))
String nodeContent=node.getAttributes().getNamedItem("car").getNodeValue()
