Usage

From source file:MyStreamFilter.java

    System.out.println("FACTORY: " + xmlif);
    System.out.println("filename = " + filename);

    FileInputStream fis = new FileInputStream(filename);

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

    int eventType = xmlr.getEventType();
