SharePoint Programming

I created a WebPart where RSS feed form a SharePoint Blog Posts list was consumed and modified to display, the two recently updated blog posts. Also, the post opens up in a new window on Click of the Post title.

"rss_text" in the below code will return your feed (two recently updated posts).

So here is the code to extract data from feed.

First,
1. Create a WebPart.
2. In CreateChildControls Call the Below method DisplayRSS() and pass the Posts list Rss Feed url( Get the RSS feed link from "View RSS" option in the Posts lists).

protected string DisplayRSS(string ListRssUrl)
{
try
{
string rss_text = "";
string title = "";
string link = "";
string description = "";

XPathDocument doc = new XPathDocument(ListRssUrl);
XPathNavigator nav = doc.CreateNavigator();
XPathNodeIterator items = nav.Select("//item");

int items_to_show = 2;
int count = 0;
while (items.MoveNext() && count < items_to_show)
{
XPathNavigator navCurrent = items.Current;

try
{
title = navCurrent.SelectSingleNode("title").InnerXml;
link = navCurrent.SelectSingleNode("link").InnerXml;
description = navCurrent.SelectSingleNode("description").InnerXml;

}
catch{ }

CleanUp(ref title,ref description); // Calling a FeedClean Function

if (description != "")
{
description = "- " + description;
description += "...";
}

rss_text += "<a href='" + link + "' target='_blank'>" + title + "</a> " + description;

if (count < items_to_show - 1)
rss_text += "<br/><br/>";

rss_text += "</div>";

count++;
}
return rss_text;
}
catch
{ }
}

protected void CleanUp(ref string title,ref string description)
{
title = title.Replace("\n", " ");
title = title.Replace("\r", " ");

description = description.Replace("<", "<");
description = description.Replace(">", ">");

description = Regex.Replace(hover_description, @"<(.\n)*?>", string.Empty); // To Remove all the html tags from the RSS feed.

title = title.Trim();
description = description.Trim();
}
