Read an XML Document with the StAX Iterator API

Read an XML Document with the StAX Iterator API

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());}               }        }
