Thank you, now this is my code, how i can add the Namespace to the
Document, i ithink this is my last Problem:
Document doc = null;
Namespace ns = new
Namespace("test","http://swt.informatik.uni-mannheim.de/2007/BomberManLevel";);
SAXReader reader = new SAXReader();
try{
doc = reader.read("Example_Level.xml");
}catch(DocumentException e){
System.err.println("Level-Datei konnte nicht gelesen werden");
}
Node node =
doc.selectSingleNode("/test:level/test:size/test:width");
if(doc != null){
Element element = (Element) node;
String text = element.getText();
System.out.println("Width: " + text);
}
