LINQ to XML的选择不起作用

我有一个XML，我使用LINQ to XML从XML文件检索数据。LINQ to XML的选择不起作用

以下是我的LINQ代码

XElement newCustOrd = new XElement("ad", 
from c in custOrd.Element("ad").Elements("adinfo") 
where ((string)c.Attribute("title")).Contains("Android") 
select new XElement("adinfo", 
    new XElement("title", (string)c.Attribute("title")), 
    new XElement("phone", (string)c.Attribute("phone")), 
    new XElement("email", (string)c.Attribute("email")) 
) 
);

的问题我在查询select语句只获取第一个元素在XML文件中。

其标题中包含Android的元素是元素数量的4

任何帮助将不胜感激

以下是在custOrd.Element("ad")，如果我的XML文件的内容

使用Elements()，而不是单一Element()你的意思是得到全部<ad>元素而不是只有第一个。
