使用LINQ to XML - 如何元素

Question

我從Gmail中的XML提要內。因而提取屬性值：

<feed version="0.3"> 
    <title>Gmail - Inbox for bagee18@gmail.com</title> 
    <tagline>New messages in your Gmail Inbox</tagline> 
    <fullcount>9</fullcount> 
    <link rel="alternate" href="http://mail.google.com/mail" type="text/html"/> 
    <modified>2012-07-19T02:43:55Z</modified> 
    <entry> 
     <title>$50 or $100 Nightly Resort Credit and Room Upgrade</title> 
     <summary>Add to Address Book | Update email address Marriott® FIND A HOTEL EXPLORE PLAN MARRIOTT REWARDS</summary> 
     <link rel="alternate" href="http://.google.com" type="text/html"/><modified>2012-07-19T01:23:00Z</modified>

      <name>me</name> 
      <email>bagee18@gmail.com</email> 
     </author> 
    </entry>   

我創建了一個LinqPad查詢這樣：

XDocument xmlDoc = XDocument.Load(@"C:\Users\Brad Agee\Documents\feeds.xml"); 

var q = from c in xmlDoc.Descendants("entry") 
where c.Element("title").Value.ToLower().Contains("resort") 
select new { 
name = c.Element("title").Value, 
url = ??, 
email ?? 
}; 

q.Dump(); 

我怎樣才能提取link標籤href屬性爲url屬性的值和email屬性的值到email屬性？

Answer 1

好吧。 Href是元素鏈接的屬性。 所以

c.Element("link").Attribute("href") 

電子郵件是筆者元素的元素

所以

c.Element("auhtor").Element("email").Value 

終於

select new 
{ 
    name = c.Element("title").Value, 
    url = c.Element("link").Attribute("href").Value, 
    email = c.Element("author").Element("email").Value 
};
