New Post: Custom Extension... Namespace a10

alexandre_fs — Mon, 15 Jun 2009 18:36:51 GMT

Has anyone ever seen this extension of the dates in this feed:

http://content-cdn.dell.com/api/feeds.svc/rss/about-dell-press-room?c=us&l=en&s=corp

Is this an Atom extension? But the feed is classified as a RSS v2.0...

Do I have to create a custom extension? Is there any documentation on how to do this?

Thank you

New Comment on "Making remote procedure calls using the XML-RPC client"

jkergosi — Fri, 29 May 2009 15:37:55 GMT

What is this line for? client.Host = new Uri("http://bob.example.net/xmlrpcserver"); Are there programming considerations beyond pointing to the correct source and target post URIs to consider? Thanks, Jason

New Post: GDATA Publishing

ghstahl — Wed, 20 May 2009 16:10:21 GMT

Hi,

Our service needs to conform to the GDATA specifications.

Can I use Argotic to accomplish this goal?

Can you point me to any implementation that has done this.

Thanks

Commented Issue: Error in DateTime parsing... specific case scenario with explanation

alexandre_fs — Thu, 14 May 2009 11:57:55 GMT

Hello. I know this is not the first post about datetime parsing, but I have a specific case that I think should be considered.
The RSSFeed (v2.0) is the following: http://www.nokia.pt/lv1web/public_pageflows/PressReleaseRSSFeed/PressReleaseRSSFeedController.jpf?pressreleaserssfeed_country=PT&pressreleaserssfeed_language=pt&pressreleaserssfeed_global=false&pressreleaserssfeed_link=http://www.nokia.pt/A4270065

It parses each item publication date correctly except in those that the day is a single digit.

for example, this item:
<item>
<title>CES 2009: Philips e Nokia juntam esforços para aumentar a interoperabilidade DLNA</title>
<link>http://www.nokia.pt/A4270065?newsid=-16520</link>
<description>....</description>
<pubDate>Thu, 15 Jan 2009 19:17:11 GMT</pubDate>
</item>

Is parsed correctly because the day is the 15th.

But in this case:

<item>
<title>Nokia 6260 slide – partilhar a alta velocidade</title>
<link>http://www.nokia.pt/A4270065?newsid=-16179</link>
<description>....</description>
<pubDate>Fri, 5 Dec 2008 21:20:27 GMT</pubDate>
</item>

the parsing is not valid. And the reason is because the day is the 5th which is only 1 digit.

How can I solve this?? It shouldn't be too hard.

Also I can't understand what's the latest release to download. If I go to SVN the revision is 33774, but throws an exception when trying to read this feed for example. If I download directly from the website, it's from 3 July, but says updated in Dec 2008, but still the DLLs are from July.... I don't know what's the latest version?

Thank you
Comments: ** Comment from web user: alexandre_fs **

Other case scenario: http://www.lge.com/about/rss/feed_list/rssPress.jhtml

This is not parsed by the current release...

To parse this type of date I added: - not very well coded :\ -

if (value.Contains("GMT") && (value.Contains("+") || value.Contains("-")))
{
value = value.Replace("GMT", "");
success = DateTime.TryParse(SyndicationDateTimeUtility.ReplaceRfc822TimeZoneWithOffset(value), dateTimeFormat, DateTimeStyles.None, out result);
}

Of course this will work only for GMT. To work properly a method similar to SyndicationDateTimeUtility.ReplaceRfc822TimeZoneWithOffset() should be added...

Commented Issue: Error in DateTime parsing... specific case scenario with explanation

alexandre_fs — Fri, 08 May 2009 11:30:27 GMT

I replaced in SyndicationDateTimeUtility class (Argotic.Common) In line 326 the parsing with this:

//------------------------------------------------------------
// Perform conversion of RFC-822 formatted date-time string
//------------------------------------------------------------
bool success = DateTime.TryParseExact(SyndicationDateTimeUtility.ReplaceRfc822TimeZoneWithOffset(value), formats, dateTimeFormat, DateTimeStyles.None, out result);
if (!success)
{
success = DateTime.TryParse(SyndicationDateTimeUtility.ReplaceRfc822TimeZoneWithOffset(value), dateTimeFormat, DateTimeStyles.None, out result);
if (!success)
{
success = DateTime.TryParse(SyndicationDateTimeUtility.ReplaceRfc822TimeZoneWithOffset(value), dateTimeFormat, DateTimeStyles.AssumeLocal, out result);
}
}
return success;

I still can't understand why it doesn't parse correctly because there is a format that matches the specified DateTime, but this way it's working... I wouldl ike to understand why though...

New Post: Consuming Twitter Search

miketrash — Sat, 25 Apr 2009 06:31:28 GMT

The atom feed from twitter search is working fine for me except two elements:
<twitter:source></twitter:source>
<twitter:lang></twitter:lang>

I don't know much about atom but I assume this is an atom extension created by twitter. How can I get these elements?

New Post: Help with RSS extensions (in VB.net)

gadavis2 — Wed, 15 Apr 2009 13:36:44 GMT

I need help converting the following into vb.net:

if(item.HasExtensions) {
var contentExtension = item.Extensions.OfType<SiteSummaryContentSyndicationExtension>().FirstOrDefault();
if(contentExtension != null) {
var encodedContent = contentExtension.Context.Encoded;
}
}

Anyone have any luck with vb.net code for extracting the content:encoded from an RSS feed? If so, any help would be appreciated. I've been searching for help with this for a couple of months now.

Thanks,

Greg

Any help with this would be greatly appreciated. I've tried converting your C code to VB...but I'm getting errors still. Can you provide me with VB code to read rss content:enconded?

Thank you,

New Post: Why two Argotic implementation in .NET2.0 and .NET3.5

Charles2009 — Mon, 16 Mar 2009 15:14:04 GMT

Hello everyone,

I am new to .NET and C#, and I'm looking for a ATOM1.0 complied Feed Parser in C#. My program is required to support all versions of .NET from .NET2.0. I saw Argotic may be helpful. I saw there are two implementations: Microsoft .NET 2.0 and Microsoft .NET 3.5. What's the main difference between them? If only ATOM1.0 is needed, is .NET 2.0 version
Argotic enough?

Your help is greatly appreciated. Thanks.

New Post: Removing extensions from RssItem.Extensions

jbigelow — Mon, 09 Mar 2009 21:35:27 GMT

Hello,

I keep getting a Null reference exception when attempting to remove an extension from an item that I know happens to contain the extension to be removed.

if (item.HasExtensions)
{
    var oldExtension = item.Extensions.OfType<ITunesSyndicationExtension>().FirstOrDefault();
        if (oldExtension != null)
            {
                    item.RemoveExtension(oldExtension);
            }
}

The null reference exception is being thrown on the item.RemoveExtension line so the extension is being found (the VS debugger confirms this as well). Is this not the proper method for removing an extension?

Thank you,
Justin

Thank you, do you have that code in VB.net? I need to declare the
variables as a certain type and I'm not sure which ones to choose
(string? object?).

Apophis — Mon, 09 Mar 2009 09:14:45 GMT

This is how I read RSS-Content:

if(item.HasExtensions) {
var contentExtension = item.Extensions.OfType<SiteSummaryContentSyndicationExtension>().FirstOrDefault();
if(contentExtension != null) {
var encodedContent = contentExtension.Context.Encoded;
}
}

New Post: Urgent! Why is this feed not reading properly:

gadavis2 — Wed, 25 Feb 2009 16:40:08 GMT

Here's some interesting data to go along with this problem...

If I copy the entire contents of that rss file to an xml file on my own webserver...then try to read it using Argotic, it works fine. It's just when I try to read that same file on daniweb that it fails to load. Could daniweb have some restriction in place that prevents other websites from reading it's rss feed? Has anyone heard of restrictions like that?

Thanks,

Greg Davis

http://www.daniweb.com/blogs/rss311962.xml#

This feed has all the proper elements and no significant errors exist after validating with feedvalidator.org. I'm attempting to read the file using both rss and atom syndication formats...but nothing is captured. What is wrong with this feed or why can't it be read using Argotic?

I would greatly appreciate a prompt reply to this problem. If you offer paid service, I'm willing to hire you for a bit for some consultation.

I also have not heard anything regarding reading the rss content:encoded issue I'm having. Your example reagarding reading extended rss for itunes doesn't help me. Can you please provide code for me to read the rs content:encoded tag?

gadavis2 — Wed, 18 Feb 2009 16:18:40 GMT

I tried this...but it didn't work...what am doing wrong? The sample code you provide for itunes doesn't really help me for the content:econded tag:

Imports Argotic.Extensions.Core

Dim feed As RssFeed = RssFeed.Create(feedUrl, settings)
For Each item As RssItem In feed.Channel.Items

Dim tmpContent As String = ""
If item.HasExtensions Then

Dim itemExtension As SiteSummaryContentItem
Try

tmpContent = itemExtension.Content.ToString()

Catch ex As Exception

tmpContent = ""

End Try

End If

THere is a known issue with some of the date-time conversion code, hopefully the fix for this issue will address this, but I will note the 'CET' time zone case you mentioned. Thanks.

Greg,

It appears the feed(s) are not properly formatted.

See http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fgopro-tec.com%2Findex.php%3Fblog%3D3%26tempskin%3D_atom for details on the validation errors on the Atom feed.
