Question

Hi I’ve manage to parse an XML file with some distances in kilometers. But as result I get list of distances of cource, but the last element in the list contains the sum of all the other elements in the list. How can I grab the last element in the list

Some source code:

for(int s=0; s<listOfRoutes.getLength() ; s++){
    NodeList listDist = doc.getElementsByTagName("distance");
    totalDist = listDist.getLength(); 

    for (int k = 0; k<listDist.getLength(); k++) {
        NodeList childs = listDist.item(k).getChildNodes();

        for (int l = 0; l < childs.getLength(); l++) {
            if (childs.item(l).getNodeName().equals("text")) {
            System.out.println(childs.item(l).getTextContent());
                //totalKM.add(childs.item(l).getTextContent()); 
            }       
        }

     }  
     System.out.println("Total Distances: " + totalDist); 
 }

I’am interested in the last element of the childs NodeList, which contains this information:

0.3 km
0.8 km
0.9 km
0.3 km
0.1 km
0.3 km
40 m
0.3 km
3.0 km

How can I grab this one?

Doesn’t listDist.item(listDist.getLength() - 1) work?
