I am trying to use a SAX Parser to parse a XML file. Although I keep getting the error below in my code:

Here Is My handler Class:

Here is my main class:
public class main {
public static void main(String[] args) throws IOException, ParserConfigurationException, SAXException {
// Create scanner
Scanner OswegoNote = new Scanner(System.in);
//Create a parser factory
SAXParserFactory factory = SAXParserFactory.newInstance();
//Make the parser
SAXParser saxParser = factory.newSAXParser();
XMLReader parser = saxParser.getXMLReader();
//Create a handler
MySaxParser handler = new MySaxParser();
//Tell the parser to use this handler
parser.setContentHandler(handler);
//read and parse the document
parser.parse("C:\\Users\\mhromalik\\Documents\\Suny Oswego\\fall2013\\csc241fall2012\\Assignment\\MyCitation.html");
}
}
And here is part of my XML file:
<Citation>
<ConferenceProceedings>
<Name>An efficient implementation of Smith Waterman algorithm on GPU using CUDA, for massively parallel scanning of sequence databases</Name>
<Publisher>Parallel and Distributed Processing</Publisher>
<ConferenceLocation>Austin,TX</ConferenceLocation>

<Pages StartPage="85" EndPage="102"/>
<Authors>
<author>L. L. Ligowski</author>

<Keywords>

</Citation>
<FormattingStyle>IEEE</FormattingStyle>
<FilePath>C:\\Users\\mhromalik\\Documents\\Suny Oswego\\fall2013\\csc241fall2012\\Assignment\\MyCitation.html</FilePath>
</Index>
I can not figure out why this error is happening. Any help would be greatly appreciated!
