Get an attribute of a dom node

MBU picture MBU · May 5, 2011 · Viewed 66.9k times · Source

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.

Your node is an Element so you just have to

Element e = (Element)node;
String name = e.getAttribute("name");
