public static void gh()
{
	 try {
		 DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
		    DocumentBuilder db =dbf.newDocumentBuilder();
		    Document doc=db.parse("G:/books.xml");
		    
		    
		    NodeList listOfPersons = doc.getElementsByTagName("current_conditions");
		    int totalPersons = listOfPersons.getLength();
            System.out.println(""+ totalPersons);

            for(int s=0; s<listOfPersons.getLength() ; s++){


                Node firstPersonNode = listOfPersons.item(s);
                if(firstPersonNode.getNodeType() == Node.ELEMENT_NODE){


                    Element firstPersonElement = (Element)firstPersonNode;

                    //-------
                    NodeList firstNameList = firstPersonElement.getElementsByTagName("temp_c");
                    Element firstNameElement = (Element)firstNameList.item(0);

                    NodeList textFNList = firstNameElement.getChildNodes();
                    System.out.println("First Name : " + 
                           ((Node)textFNList.item(0)).getNodeValue().trim());
                }
            }
		  } catch (Exception e) {
		    e.printStackTrace();
		  }
