Stax problem

[John Eric Hamacher]

Hello:

I'm using the implementation of Stax which comes with Java 6. My problem is about the Location object and when it cares to report location information. When I parse a file i'd like to be able to tell the user line numbers of data when there is a problem (e.g. if a certain number is out of range, I'd like to tell the user the line number of the piece of data in question). However, xmlStreamReader.getLocation().getLineNumber() never seems to return location information. So when does it? How can I coax this information out of stax when I need it?

Thanks, Eric

	@Override
	protected void parseFile() throws XMLStreamException, Exception {
		XMLStreamReader xmlStreamReader = produceXMLStreamReader();
		parseXMLStreamReader(xmlStreamReader);
	}
		
	private XMLStreamReader produceXMLStreamReader()
            throws XMLStreamException, FileNotFoundException {
		XMLInputFactory factory = XMLInputFactory.newInstance();
		factory.setProperty(XMLInputFactory.IS_SUPPORTING_EXTERNAL_ENTITIES, false);
		factory.setProperty(XMLInputFactory.IS_VALIDATING, false);
		return factory.createXMLStreamReader(new FileReader(uploadedFile));
	}
		
	private void parseXMLStreamReader(XMLStreamReader xmlStreamReader)
            throws XMLStreamException, SQLException, Exception  {

		String currentLocalName = null;
		String currentText = null;
		String currentDistrict = null;
		while(xmlStreamReader.hasNext()){
		    xmlStreamReader.next();
		    System.out.println("LN = " + xmlStreamReader.getLocation().getLineNumber());
		    if(xmlStreamReader.getEventType() == XMLStreamReader.START_ELEMENT) {
				currentLocalName = xmlStreamReader.getLocalName();
		    }
		    if(xmlStreamReader.getEventType() == XMLStreamReader.CHARACTERS) {
		    	
		    	currentText = xmlStreamReader.getText();
		    }
		    if(xmlStreamReader.getEventType() == XMLStreamReader.END_ELEMENT) {
		    	currentLocalName = xmlStreamReader.getLocalName();

		    }
		}
	}

Moving to our XML forum.

Now I am curious - what does this statement return if not a line number?

xmlStreamReader.getLocation().getLineNumber()     

Perhaps the xmlStreamReader does not track line numbers by itself and
you should enclose the FileReader in a java.io.LineNumberReader
