Я думаю, что строка № 2 создает проблему, которая
<!--RSS generated by RSSviaXmlTextWriter at Thu, 02 Mar 2017 16:35:42 GMT-->
очевидно, что первая строка обрабатывается как комментарий xmlpullparser, но проблема связана со второй строкой. Парсер, я полагаю, не может разобрать вторую строку, потому что он ищет начальный тег и встречает символ .
Вот мой парсер
public class SitesXmlPullParserTribuneLocal{
static final String KEY_SITE = "item";
static final String KEY_NAME = "title";
static final String KEY_LINK = "link";

BufferedReader reader = new BufferedReader(new InputStreamReader(fis));
// point the parser to our file.
xpp.setInput(reader);
// get initial eventType
int eventType = xpp.getEventType();
Log.e("TagName Local", String.valueOf(eventType));

boolean actual_work = false;
// Loop through pull events until we reach END_DOCUMENT
Log.e("You Reached To", "Mark1");
while (eventType != XmlPullParser.END_DOCUMENT) {

XML-файл в порядке
это анализирует файл, а затем вы можете использовать DOM и извлечь элементы, ...
DocumentBuilderFactory builderFactory =DocumentBuilderFactory.newInstance();
builderFactory.setNamespaceAware(true);
DocumentBuilder builder = builderFactory.newDocumentBuilder();
// PARSE
Document document = builder.parse(new InputSource(new InputStreamReader(fis)));
