Ich hab es jetzt mit getAttribute() gelöst. Bin mir jetzt nur nicht so sicher ob das eine "elegante" Lösung ist 
[code=Java]try {
BufferedReader bf = new BufferedReader(new InputStreamReader(
System.in));
String xmlFile = "AIR_A1+ESTAT+2.5.xml";
File file = new File(xmlFile);
if (file.exists()) {
DocumentBuilderFactory factory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(xmlFile);
// Get nodes list of all elements
NodeList list = doc.getElementsByTagName("*");
for (int i = 0; i < list.getLength(); i++) {
// Get element
Element element = (Element) list.item(i);
String attrValue = element.getAttribute("conceptRef");
System.out.println(attrValue);
}
} else {
System.out.println(xmlFile + " (file name) doesn't found!");
}
} catch (Exception e) {
e.getMessage();
}
[/code]
