Load the string up into the HTML Agility Pack then select all li elements inner text.

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml("following:<ul><li>Go to AppStore</li><li>Search by him</li><li>Download</li></ul>");

var uls = doc.DocumentNode.Descendants("li").Select(d => d.InnerText);
foreach (var ul in uls)
{
    Console.WriteLine(ul);
}

+1 for HTML in the wild, you can't rely on well-formed XHTML, so Agility Pack is needed. – D'Arcy Rittich May 11 '12 at 14:40

Wrap in an XML root element and use LINQ to XML:

var xml = "For the iPhone do the following:<ul><li>Go to AppStore</li><li>Search by him</li><li>Download</li></ul>";
xml = "<r>"+xml+"</r>"; 
var ele = XElement.Parse(xml);  
var lists = ele.Descendants("li").Select(e => e.Value).ToList();

Returns in lists:

Go to AppStore 
Search by him 
Download

+1 for using XML, though in small cases as this, is it not faster to just parse the string? – May 11 '12 at 14:39
