How do I create an RSS feed in ASP.NET?
Actualy I want to output like this. Clik on an RSS icon, open the RSS bookmark box and subscribe the user. After that, clik on the RSS feed link, create RSS bookmark to show RSS, update data.
At the end of the day an RSS feed is an XML document that adheres to a predefined schema. So in the simpliest terms all you need to do is populate that XML and make it accessible to web users. You can also put information in the head of your web page markup to inform the browser that an RSS feed is available to them (this is optional).
You have a couple of options depending on the .NET framework version you are using:
.NET 2 : Get hold of the RSS XML schema you want to work with and populate as you would with any XML document.
.NET 3.5 : 3.5 introduced System.ServiceModel.Syndication, this wraps up the various RSS formats that are available and makes the process of creating your feed much easier. An example of working with these classes can be found here:

More information on the Syndication namespace can be found here:

Finally, as you develop your feed you can use the following to validate your XML:
http://validator.w3.org/feed/

SO i have a webview displaying user defined websites. I want to autodetect if that url contains any rss feed and post it in a Label/textarea.
The most straight forward way is to parse the HTML into a DOM document, then traverse the document looking for nodes that define RSS links. You may try using QXmlSimpleReader but this can be frustrating because most HTML is not well formed XML so you will have to handle exceptions.
In an answer to this question, the following SourceForge project was recommended. This might be worth a look.
Is there any way to use atom feed as a content provider in WebSphere Portal 7?
Let's say I have 2 portlets on a page which are representing main part and footer. I have one atom feed with 2 entries. I need to show the first entry as html in the main part and the second entry as html in the footer.
Please, advise any solutions based on your experience or confirm that it is only possible to do by writing your own custom portlet.
I'm not sure I completely understand the requirement for the feed to display the first link in one portlet and the next link in a different portlet, but you could try using the Syndicated Feed Portlet. Here is an explanation: http://www.ibm.com/developerworks/websphere/zones/portal/catalog/doc/1wp1001p3/index.html
Here is the download from Lotus Greenhouse: https://greenhouse.lotus.com/plugins/plugincatalog.nsf/assetDetails.xsp?action=editDocument&documentId=AAC7B8951F4C69CA8525771C004993D7
This allows you to integrate a feed with minimal portlet customization.
I developed an RSS feed following a tutorial and I think the .xml file itself is in order. However, I have two problems:
When people click on the RSS link, it doesn't automatically load into their RSS readers
For those that don't have an RSS reader, clicking the link results in a page full of code which is not very understandable
I was hoping that there might be some tips on how to easily realize this.
Try to remove the <![CDATA[ and ]]> in the description tag.
I downloaded your xml, changed those lines, tested it on my server, and it worked in google's rss reader.
This is a browser and user profile dependent issue in how the RSS link is going to react when clicked on.
If the user has the action set up to automatically load it into their feed reader of choice, it will do that.
If they don't, then it won't.
For those that just see a raw dump, it could be that they're using a browser that does not support RSS feeds and will dump out the XML as raw text. Google Chrome (at least still in version 18) without the use of extensions or add-ons will usually be the dump truck culprit here.
Got an established libsyn rss feed, got a new drupal website for the podcast. Libsyn provides a player but not correct aesthetic. I can upload and play mp3 files with audio module and mp3player module, and like the mp3 player's output, a simple flash player, but I don't want to be manually moving the podcast audio files (mp3) over every week. Looked at importing automatically with Feeds, but it's not working and besides that's creating extra files unnecessarily on the drupal site.
Just want to use the mp3player modulee's flash player in a drupal page, which feeds the latest mp3 file from a libsyn rss feed. Don't really need to store or play multiple episodes, just the latest episode.
How would you do it?
Create a content type for my podcasts with a title and a field for the URL of the MP3
Use FeedAPI and map the title to the title of the node
Map the file URL to the URL field
Use Contemplate to set the URL field to display as [swf file="token_for_URL_field"], which will use the SWF Tools module and whatever player I've selected to play the file
So you need these modules CCK, Contemplate, FeedAPI, and SWF Tools, and that should do the trick.
Why don't you have your own site be the master and libsyn get it from you? Do they not allow an import feature, with which you'd keep your existing RSS through them. Then you can have total control over your site and push the content to all kinds of other great podcasting networks.
Realize I may have no idea about libsyn works.
When you say feeds didn't work, how did it fail? Are you using feed mapper? You may need to write a custom plug-in for feed mapper to get it to do the right thing with the video files. Feed api supports expiring imported feed items so you should be able to get it to automatically delete old ones. I'm not sure whether the video files will be automatically deleted when the nodes are. If not, you should be able to make this happen by implementing nodeapi's delete op for the content type you are using to store your imported rss items.
Alternatively, maybe you could just harvest the video's url on libsyn, and have the player use that. I don't know whether there's a good player which supports using a field's data for the location of the source it should play.
Also, if you haven't already, I'd encourage you to post your question on groups.drupal.org since that's read by lots of drupal experts.
I am using google reader for my RSS, i want to export all my shared or starred rss items to HTML to take this html and put on my website
Do any one have an idea about?
And one important thing as well, can i page through this html? i mean to export as pages not all in one html page to let the user on my site page through my starred feeds.
Thanks,
With XSTL you can transform XML to any format you want, including HTML. You can do the transformation on the server, or with modern browsers like IE6+ and Firefox2+ you can do the transformation on the client side. XSTL isn't very pretty as a programming language, but the concept is pretty neat.
I don't know if you can link directly to the RSS feed XML so that it's always up to date. I think Google requires that you authenticate and have permission to access the feed.
You can read from an RSS with jQuery by selecting and iterating through the tags rather easily. Additionally, you can perform conditional-checks on attributes etc as well.
