Creating the Filter

The next step is to instantiate a file input stream and create the stream filter:

FileInputStream fis = new FileInputStream(filename);
                
XMLStreamReader xmlr = xmlif.createFilteredReader(
    xmlif.createXMLStreamReader(fis), new MyStreamFilter());

int eventType = xmlr.getEventType();
printEventType(eventType);
while(xmlr.hasNext()) {
    eventType = xmlr.next();
    printEventType(eventType);
    printName(xmlr,eventType);
    printText(xmlr);
    if (xmlr.isStartElement()) {
        printAttributes(xmlr);
    }
    printPIData(xmlr);
    System.out.println("-----------------------------");
}
