First thing you need to do is modify your xml. You have tag mismatches on your date tags. You have <Date>2015/9/12</Data>. Notice your ending tag says Data instead of Date. Then you can do the following:

您需要做的第一件事是修改您的xml。您的日期标记上有标记不匹配。您有 2015/9/12 。请注意您的结束标记是数据而不是日期。然后你可以做以下事情:

var events = doc.Descendants("Event").Where(x => x.Element("Date").Value == "2015/9/12" || x.Element("Date").Value == "2015/9/13");
