I have an xml feed from Gmail as such:

<feed version="0.3">
    <title>Gmail - Inbox for [e-mail]</title>
    <tagline>New messages in your Gmail Inbox</tagline>

I created a LinqPad query as such:

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();

How can I extract the value of href attribute of the link tag into the url property and the value of email attribute into the email property?

Answer 1

Well.
Href is an attribute of the element link.
So

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

email is an element of the element author

So

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

finally

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