From source file:org.pencilsofpromise.rss.RSSFragment.java

    try {//from  ww w.j  av a 2s. c  o m
        // setup the url
        URL url = new URL(urlToRssFeed);

        // create the factory
        SAXParserFactory factory = SAXParserFactory.newInstance();
        // create a parser
        SAXParser parser = factory.newSAXParser();

        // create the reader (scanner)
