New Post: Modules in Atom Feeds

tlianza — Mon, 07 Sep 2009 23:50:07 GMT

Is it possible to have modules for Atom feeds, or just RSS?

In looking through FeedReader's initialize method, the only codepath that iterates over modules is inside the "RSS" conditional. Atom feeds don't appear to look for modules.

Is that right? If so, is it by design? If not, may I submit a patch to add it?

Thanks,

Tom

NEW POST: how to publish a feed

sandroriz — Sat, 31 May 2008 18:34:49 GMT

I really appreciate this library, but I find it lacks a little of documentation (or I'm so stupid that I didn't find it).

After building a feed with its channel properties and created its items collection, is there a method or a propriety (such a feed.ToXml ) that returns the xml stream ?

Thanks
Sandro

Hi!

Thank you! At this moment I don't know yet it the product will be realized, we are at the analysis stage, and I was searching for libraries and tools that we may need. I'll let you know if I use your library :-)

Hi Marco,

sure, no problem! But it would be great if you would make a short notice about FeedDotNet and link to this site somewhere in your program (e.g. in the "about" dialog)

PS: may I know what is the product you are working on? I could refer to it from my side as well

Hi!

I have a question about the License of FeedDotNet: is it possibile to use it in a commercial closed-source product?

Thanks in advance!

Project Description
FeedDotNet is a very small RSS yet powerful library for the .NET environment written in C#. As I searched for a good RSS library for our Social RSS Software Mindity, I came across several similar packages, but they were either incomplete or bug-ridden. For example, the classic RSS.NET is not open-source anymore, cannot read Atom feeds and has some bugs with enclosure handling.

The FeedDotNet library supports all current RSS and Atom formats, and can be expanded by integration of new modules.

NEW POST: Updated Atomparser.cs to support feeds with source attributes

JoshLedgard — Sun, 04 Nov 2007 00:42:25 GMT

I noticed that the feedreader didn't properly support feeds that contained the source element. It would replace the item titles with the titles of the source element. It also didn't extract the source elements.

I have the updated source here: http://ledgards.com/files/folders/612/download.aspx

If you are interested, I used your library to create a plugin for for Windows Live Writer. You can find it here:

Thanks,

Kostik — Mon, 22 Oct 2007 09:28:23 GMT

Hi and thank you for rising this issue. That's a bug in the System.DateTime.TryParse() method. Your feed has a special date format in the <pubDate> element, like this: Thu, 18 Oct 2007 21:03:29 Etc/GMT. To fix this, just add following line to the static constructor of the FeedDotNet.Utilities.DTHelper class:

timeZones.Add("ETC/GMT","+0000");

I will also inculde this fix in the next release of FeedDotNet.

Yes i tried with a different UserAgent without success.
Thanks for the new method.

I use FeedDotNet on linux using mono 1.2.5.1, i get errors. I will update mono when new release come out. With other Feed library i had less errors.

I will use the new method later, ignore the feed on error that need custom http headers.

Thanks again.

The feed
http://www.actu-mmorpg.com/index2.php?option=com_rss&feed=RSS2.0&no_html=1
requires no UserAgent-header OR requires both UserAgent+Accept headers. Please check the updated FeedReaderSettings class (FeedDotNet ver. 1.2.1.1). It now has 3 new members:
string HttpUserAgentString
string HttpAcceptString
Dictionary<HttpRequestHeader, string> HttpHeaders

Defaults of HttpUserAgentString and HttpAcceptString are set to the browser defaults, so that we can simulate a real browser agent (some feeds, thereunder http://www.actu-mmorpg.com/index2.php?option=com_rss&feed=RSS2.0&no_html=1 require this behavior). If you are still in situations where your browser (or other feed agent/library) shows a feed as expected, but the FeedDotNet doesn't, you can experiment with adding of custom Http-headers to the HttpHeaders-collection.
