Often, all you need to do in an application is send an HTTP request to a Web site. The Web site sends the data back via XML, and the easiest way to work with that data is to use LINQ queries. In this episode, Robert shows you how to use LINQ to XML to make sense of the XML data a Web site sends you. He gives  examples of working with an RSS feed, retrieving images from Flickr, querying for wineries and wines using Wine.com, and returning movies from NetFlix. You'll see basic queries, see how to retrieve data from elements and attributes, and see how to work with namespaces. Check out Robert's blog for all the code he used in this episode. en Thu, 20 Jun 2013 06:06:09 GMT Thu, 20 Jun 2013 06:06:09 GMT Rev9 Re: Visual Studio Toolbox: Using LINQ to XML to Query Data on the Web posted by jvs_ca

Lets try one more time:
We want to see C++11 with visual studio using GCC and clang.

Do you refuse to listen because the compiler we want to use is GCC which is not a microsoft product ?

Waiting for the next episode you announced (using Linq to XML to write XML instead of querying).
Great job!

Never use the query operator Count() to check for the presence of items in a sequence! You should generally use Any(), as Count() needs to read the complete sequence. (In your example prefer !posts.Any() over posts.Count() == 0; because you are materializing the sequence twice, in Count() and on iterating the sequence.)
