c# - 如何用正则表达式解析字符串

Question

如何从此文本中获取 List()：

For the iPhone do the following:<ul><li>Go to AppStore</li><li>Search by him</li><li>Download</li></ul>

应该包括：去 AppStore，由他搜索，下载

Answer 1

将字符串加载到HTML Agility Pack中，然后选择所有li元素内部文本。

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);
}

Answer 2

包装一个 XML 根元素并使用 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();

返回lists：

Go to AppStore 
Search by him
