createFilteredReader - how does it work?

[mickey0]

Hello,
I just would like use XMLStreamReader (going on with reader.next() in a loop) to read an xml BUT I want to skip whitespace, '\n', '\t' and similars.
I thought the solution was XMLStreamFilter ed and I coded it (maybe in a wrong way either I didn't understand how to use it):

//main
FileInputStream source = null;
XMLInputFactory inputFactory = null;		    
inputFactory.createXMLStreamReader(source);
source = new FileInputStream("myfile.xml");
inputFactory =  XMLInputFactory.newFactory();   
XMLStreamReader reader = inputFactory.createFilteredReader(inputFactory.createXMLStreamReader(source), new MyStreamFilter() );

while ( reader.hasNext() ) {
   int event = reader.next();
}

//MyStreamFilter.java
public class MyStreamFilter implements javax.xml.stream.StreamFilter {
	public boolean accept(XMLStreamReader reader) {
		if (reader.isWhiteSpace() || 
			(reader.hasText() && ( reader.getText() == "\n"   || reader.getText() == "\t"))   ) { 
			return false;
		}
		return true;
	}
}

Something wrong happen: accept() is called, return true, and the problem exit printing 'null' on the console. none exceptions.

sorry the code was fine; I've made a mistake; however, is the statment IF fine to catch all wihitespace, \t, \n, \r\n characters? I guess I'm forgetting same of them.
thanks
