Hey there,
I am just a little confused with the code below, i parse the XML file although i cant call functions from outside the main. My programming isnt really up to scratch. Ive had a long break so now im paying for it :(
Any help/ suggestions would be very grateful!
package Util;

public class XMLreader{
public static void main(String argv[]){

DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
doc.getDocumentElement().normalize();
System.out.println("Root element: " + doc.getDocumentElement().getNodeName() + "\n");
NodeList nodeLst = doc.getElementsByTagName("Trackpoint");
//this works but i wish to call the functions from outside this class
readLatitude(nodeLst, 5);
}catch(Exception e){
e.printStackTrace();
}
}
public static float readLatitude(NodeList nodeLst, int index){
float latArr[] = new float[nodeLst.getLength()];
try{
