Why SAX parser parse tags in rss feed which is invisible?

I'm trying writing a rss reader in android app by using sax parser. I tried some rss feed and it all worked very well, except this rss feed I can't run the app due to mismatched tag error: http://ift.tt/1rSsqsj. When i run this code to check what tags the sax parser parse through: @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { Log.d("rss", localName); }

I received the log which shows invisible tags in rss feed web like "meta" and "script" tag without my wantted tags in rss like "item", "description",... Finally, how can I parse tags in this rss feed correctly
