    Default Help with XML Parsing

    I was working with XML parsing.Since I am learning it just now it would be good if somebody helps me to find the errors in my code

    This is the code snippet:

    I have declared all the variables correctly...

    try {
              myURL = new URL(fao_addr);
    catch (MalformedURLException e)
    	try {
    			feed = xmlReader.read(fao_addr);
              	} catch (DocumentException e) {
    	String xpathExpression = "/Data/FAO";
            nodes = feed.selectNodes(xpathExpression);
            String xpathExpression2 = "/Data/FAO/region/hasMember";
            List<? extends Node> subnodes = feed.selectNodes(xpathExpression2);
            System.out.println("The FAO Members by region in "+language+ " language are : ");
            for (Node node : nodes) {
            	Node region = node.selectSingleNode("region");
            	for(Node subnode : subnodes)
            		String acc_variable="nameShort"+language;
            		Node short_name = subnode.selectSingleNode(acc_variable);
            		System.out.println(short_name.getText()+"\n");                      //Error Here..

    This is the XML file I am trying to access


    This is the error I get in the mentioned line

    Exception in thread "main" java.lang.NullPointerException

    Thanks in advance

    Use code tags for your code, quote or code tags for your error messages. Post full stack traces of any exceptions.
