Using iStockphoto user atom feeds

31. August 2009 13:53 by Brian in Projects - Comments: (0)

On a new website for Add Image (http://www.addimage.net/) we added a stock gallery which uses the Atom feeds from www.iStockPhoto.com which allow a user to use a data feed of their 10 latest images.

The datafeed is in Atom format. Using Microsoft Linq and C# I wrote the following code which grabs the users latest images and displays them on a web page complete with links back to each image to purchase.

You need to change the ID which is set to 275125 in this demo to be your own iStockPhoto user ID.

<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="utf-8" Debug="false"%>
<%@ Import Namespace="System.Xml" %>
<%@ Import Namespace="System.Linq" %>
<%@ Import Namespace="System.Xml.Linq" %>
<script runat="server">
protected void Page_Load(Object Src, EventArgs E)
{

XmlReaderSettings settings = new XmlReaderSettings();
XmlUrlResolver resolver = new XmlUrlResolver();
XmlReader reader = XmlReader.Create("http://www.istockphoto.com/istock_myfiles_rss.php?ID=275125", settings);
XNamespace ns = XNamespace.Get("http://purl.org/atom/ns#");
XDocument feed = XDocument.Load(reader);
var items = from item in feed.Descendants(ns + "entry")

select new {Title = item.Element(ns + "title").Value, Link = item.Element(ns + "link").Attribute("href").Value, Summary = (string)item.Element(ns + "content")} ;

Repeater1.DataSource = items;
Repeater1.DataBind();

}
public string makeimagelink(string inval) {

return inval.Replace("http://www.istockphoto.com/file_closeup.php?id=","").Replace("&refnum=275125&source=rssuserimages","");
}
