Selenium Webdriver:在列表中选择具有特定跨度标题的单选按钮

我有以下 HTML 在本例中在我的 ul 中有 2 个项目。现在我想检查（单击）<span title = "SeleniumUpload">的单选按钮。在此HTML中只有一个元素，但可以有更多元素。

如何找到此元素？

网页示例：

<ul id="ctl00_cpm_AlbumMain_thumbs" class="listAlbums clearfix nospace-bottom" mediastorepartnertype="extrafilm" style="height: 160px;">

到目前为止，我已经有了这个，但是span的title属性返回一个空字符串。这是为什么呢？

var albums = driver.FindElements(By.ClassName("albumTitle")); 
Console.WriteLine("Found {0} photo-albums", albums.Count);
foreach (var we in albums)
{
var span = driver.FindElement(By.TagName("span"));
String title = span.GetAttribute("title"); // returns empty string, I need this title value
Console.WriteLine("we.text:'{0}' title:''{1}",we.Text, title);
// work around
if (we.Text.Contains("Seleni")) // I should be able to check on span title
{
  var input = we.FindElement(By.CssSelector("input[id*='ctl00_cpm_AlbumMain_']"));
  var id = input.GetAttribute("id");
  Console.WriteLine(we.Text + " Id:" + id);
}
}
