Stepping through Events

In this example, the client application pulls the next event in the XML stream by calling the next method on the parser; for example:

try {
    for (int i = 0 ; i < count ; i++) {
        // pass the file name.. all relative entity
        // references will be resolved against this as
        // base URI.
        XMLStreamReader xmlr =
            xmlif.createXMLStreamReader(filename,
                new FileInputStream(filename));
        // when XMLStreamReader is created, it is positioned
        // at START_DOCUMENT event.
        int eventType = xmlr.getEventType();
        printEventType(eventType);
        printStartDocument(xmlr);
        // check if there are more events in the input stream
        while(xmlr.hasNext()) {
            eventType = xmlr.next();
            printEventType(eventType);
            // these functions print the information about
            // the particular event by calling the relevant
            // function
            printStartElement(xmlr);
            printEndElement(xmlr);
            printText(xmlr);
            printPIData(xmlr);
            printComment(xmlr);
        }
    }
}

Note that next just returns an integer constant corresponding to the event underlying the current cursor location. The application calls the relevant function to get more information related to the underlying event. There are various accessor methods which can be called when the cursor is at particular event.
