I have a script for a news ticker that displays date and title of all news in a SharePoint list (see code below).
Rather than displaying the info for all the news articles in the list I would like display only the first 3 news articles in the list.
How do I need to modify the code below to see only the first three news articles in the ticker?

Code:

            				contentType: "text/xml; charset=\"utf-8\""

        			});

			} //end repeat

			function processResult(xData, status) {

				var liHtml = '<li><span></span><a href="#" '

		        	});  // alert(xData.responseText); alert(URL_NEWS); alert(URL_BONE); alert(liHtml)

				$("ul#ticker01").html(liHtml).liScroll();

			} //end process result

			repeat();
