Are there any built in libraries/classes in VB 2008 to help to create an RSS reader?
Are there any tutorials online that would help?
Please provide links when answering the second part of the question.
System.ServiceModel.Syndication contains a bunch of classes for creating and consuming RSS and Atom feeds.
Edit: I've never used these classes, so I can't give any examples from my own code. However, a quick search turned up some examples that seem pretty good. Sorry they're not in VB, but the important parts (using the Syndication classes) are mostly the same in both languages.

Not exactly built in.
RSS documents are XML documents; you do have XmlDocument or can XML serialize a class to create that RSS feed.

dont get to harsh on me for asking this question, I know this has been asked many times. But the examples I found on the internet are either old or I am having difficulties to port them on to iOS5-Xcode 4.2.1. So I am really looking for a updated simple example where I can parse a simple XML file from an URL, store the values and display them in a tableView. I am looking for some working examples using NSXMLParser. In case if one of you guys have some info about where I can find a working example/internet link which I can follow and make it work on my machine, so that I can play and get some hands of experience on dealing with XML data, before I go on to work with the complex XML data files.
Any one who can post some code is also highly appreciated, as it would help beginners like me.
have you checked this tutorial of parsing XML data with NSXMLParser -
http://wiki.cs.unh.edu/wiki/index.php/Parsing_XML_data_with_NSXMLParser
i think your are looking for this.
Also there is an another good way to do this is using TBXML framework - https://github.com/71squared/TBXML
I'm looking to do a little iOS app that uses has some very basic YouTube interaction. When I say basic, I really mean it: All it needs to do it pull in the uploads from a particular user, the videos' links, titles and maybe a thumbnail.
I've been looking at the Google developer docs for YouTube and nothing seems to be of help. It seems that the data is stored in an XML format, but it seems completely different to the structure of the sample XML in the docs. I don't know whether I'm using the wrong link (this is a sample of what I'm looking at now), but I just get a really messy XML document.
I've really no idea where to start on this one (with regards to a parser) - it just looks so messy. If someone could point me in the right direction with this, maybe even a with some sample code on a parser, I'd be incredibly grateful.
Thanks,
K
Have you considered making use of gdata-objectivec-client api http://code.google.com/p/gdata-objectivec-client/ It comes with samples which provide exactly what you are looking for.
Here's a very concise and easy-to-read example using NSXMLParser. It provides an example xml and shows you how to parse its elements and populate a custom object with the values.
i can suggest you to use LIBXML 2.2 it's easy to use and you can use Xpath Query to fetch whatever you want from any messy file.
To learn how to use that look at this page. link
The XML link you provided looks like the atom feed. If you don't feel like parsing the XML in your code, you can try the TouchRSS (https://github.com/TouchCode/TouchRSS) which I used to parse the youtube RSS feed. The RSS feed version should be in version 2 so the url you provide should change to http://gdata.youtube.com/feeds/base/users/DJ3Lau/uploads?orderby=updated&alt=rss&v=2.
OK, I managed to read from an XML file using NSXMLParser, but now I don't know how to write to an XML file. I have an XML file, say:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<user id="abcd" password="pass1"/>
<user id="efg" password="pass2"/>
</root>
Now when a new user enters details, I want to store them in a new tag. Lets say like, the id is "hhhh" and password is "pass3".
I want to add a new tag with attributes as such:
<user id="hhhh" password="pass3"/>
to the XML file.
How should I do this? Please explain in an elaborate way. I am a newbie here. Any links to tutorials or examples will be much helpful.
Thanks.
Check out the Tree-Based XML Programming Guide. You might use NSXMLDocument and friends. You could also search the web for open-source alternatives (there are plenty that parse and a few that write). A quick Google search for "using NSXMLDocument" yields several third-party tutorials.
It's better that you read the documentation yourself first and ask more specific questions. Help us help you. :-)
There's a number of really good third party XML parsers you can take a look at that will probably make it easier on you.
Here's a good post I found talking about them. http://www.raywenderlich.com/553/how-to-chose-the-best-xml-parser-for-your-iphone-project
Try using kissxml.
The goal is to create an NSXML style API that can used in environments without NSXML (e.g. iPhone).
KissXML was inspired by the TouchXML project, but was created to add full support for generating XML as well as supporting the entire NSXML API.

I'm looking for an Objective-C library for an iOS app that will parse and display articles form an RSS feed.
Specifically,m I'm looking to make an app for a news website. The framework should be able to work with various RSS XML structures if possible. (Well, two different news sites. One uses Wordpress-generated RSS and one does not.)
MWFeedParser is another interesting library to look into.
How about https://github.com/touchcode/TouchRSS?
My drop-in solution (deals with Wordpress' RSS 2.0 and the Atom 1.0 format as well): http://github.com/H2CO3/RSSKit
You could use Apples NSXMLParser Class. Or you could use the C-based libXML2.
This library is about as old as this question: https://github.com/NextfazeSD/WordPressSyncer. It syncs WordPress blogs from the server, saving data locally in a core data database.
I am looking to test an RSS Feed I have created and I am looking for some good RSS Feed applications to test with.
Don't just try a bunch and see if it works -validate it. Let me google those for you:
W3C RSS validator
Experimental Online RSS 1.0 Validator
Firefox should work well enough for basic testing. You could also try using Google reader.
It would be worth testing the feed in Safari.
Also, if you're using Mac OS X, here are some good applications to test it in:
NetNewsWire
Apple Mail (comes with OS X)
NewsFire
Times
However, if it is a valid feed, you should be OK.

Don't forget Outlook. Large market share and its own quirks.
Circa 2009, one great answer was the python library and website at http://www.feedvalidator.org/. It was supposed to be very picky and have lots of tests.
The code still exists at https://github.com/rubys/feedvalidator but hasn’t gotten much attention since circa 2008. It could be a good starting point for a newly-updated library. All the tests could make that easier;
there’s a py3 branch with a bit of progress on it.
