I hope you can help me. I get an NullPointerExeption when I want to Put the NodeList / Node to my Map:
Map <String, NodeList> config = null;
public void loadConfiguration() {
helper helper = new helper();
NodeList nodes = null;
nodes = helper.getXPathFromFile("/root/*", "conf/config.xml");
if (nodes.getLength() > 0) {
for (int i = 0; i < nodes.getLength(); i++) {
String NodeName = nodes.item(i).getNodeName();
NodeList NodeItem = (NodeList) nodes.item(i);
System.out.println(NodeName); // Here the right Name puts out
System.out.println(helper.nodelistToString(NodeItem)); // here right inside XML-Code put out
config.put(NodeName, NodeItem); // Here comes the NullPointerEx.
}
}
}
