XDocument xDocument = XDocument.Load("...");
IEnumerable<XElement> elements = xDocument
.Element("lfm")
.Element("events")
.Elements("event");
try
{
foreach (XElement elm in elements)
{
comm.Parameters.AddWithValue("extID", elm.Element("id").Value ?? "");
comm.Parameters.AddWithValue("Title", elm.Element("title").Value ?? "");
comm.Parameters.AddWithValue("HeadlineArtist",
elm.Element("artists").Element("headliner").Value ?? "");
但是我想要属性为“size=large”的元素“image”的值,我一直在寻找整夜,这是我最接近的:
comm.Parameters.AddWithValue("LargeImage",
elm.Descendants("image")
.FirstOrDefault(i => (string)i.Attribute("size") == "large").Value);
