This tip shows an example of how to use the Iterator API to read from an XML file:

import javax.xml.stream.*;import javax.xml.stream.events.*;import java.io.*;public class StAXBasicEventReader{   public StAXBasicEventReader(){}    public static void main(String[] args)      {      XMLInputFactory XMLif=null;      XMLEventReader XMLer=null;                    System.setProperty("javax.xml.stream.XMLInputFactory",                             "com.sun.xml.stream.ZephyrParserFactory");            //get an XMLInputFactory object         XMLif=XMLInputFactory.newInstance();             //setting the XMLInputFactory corectly         XMLif.setProperty("javax.xml.stream.isSupportingExternalEntities",Boolean.TRUE);XMLif.setProperty("javax.xml.stream.isNamespaceAware",Boolean.TRUE);XMLif.setProperty("javax.xml.stream.isReplacingEntityReferences",Boolean.TRUE);                                          //getting an XMLEventReader object      try{         XMLer=XMLif.createXMLEventReader(          "file:///C://Data_Local//xml//docs//",         new FileReader("C://Data_local          //xml//docs//AirWings_xml.xml"));                  }catch(java.io.FileNotFoundException e)            {System.out.println(e.getMessage());         }catch(javax.xml.stream.XMLStreamException e)                   {System.out.println(e.getMessage());}                                       //getting the events      try{         while(XMLer.hasNext())               {               XMLEvent event=XMLer.nextEvent();               //XMLEvent event=(XMLEvent)XMLer.next();               int event_type=event.getEventType();                   switch(event_type)      {      case XMLStreamConstants.START_DOCUMENT:      System.out.println(">Start-Document<"+"Code:"+event_type);      break;                               case XMLStreamConstants.END_DOCUMENT:      System.out.println(">End-Document<"+"Code:"+event_type);      break;                                                                                   case XMLStreamConstants.START_ELEMENT:      System.out.println(">Start-Element<"+"Code:"+event_type);      break;                                //...      }                                                                                     }                //clean up                    XMLer.close();     }catch(javax.xml.stream.XMLStreamException e)               {System.out.println(e.getMessage());}               }        }
