first of all, I went to the Yahoo RSS News website(http://news.yahoo.com/rss/) then click the orange image XML and copy the RSS feed address(ex. http://rss.news.yahoo.com/rss/topstories ). After that, I went to the XHLD's administration screen, and put the address in the URL blank. I press submit and then the screen display the following :
