知道如何就很简单！

var artistsAndImage = from a in feed.Descendants("artist")
                      from img in a.Elements("image")
                      where img.Attribute("size").Value == "big"
                      select new { Name = a.Element("Name").Value
                                 , Image = img.Value};

这将返回所有艺术家的所有姓名和大图像.

This will return all the names and big images for all the artists.
