XML

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("-----------------------------");

}

Capturing the Event Stream

The next step is to capture the event stream. This is done in basically the same
way as in the

sample.

Filtering the Stream

The final step is the filter the stream:

public boolean accept(XMLStreamReader reader) {

if(!reader.isStartElement() && !reader.isEndElement())

return false;

else

return true;

}
