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.

I'm quite new in Objective C programming and I'm trying to make an application that returns all the link addresses in HTML page. In that case i shouldn't just parse the HTML, but get these links intercepting them from the page's network request.
Is it possible to intercept the application's network requests or something?
Thanks
Coincidentally, Ray Wenderlich's rather AWESOME iOS tutorial site posted this article in the last hour. As you are new to iOS/ObjC, I highly recommend reading it thoroughly.
Let’s say you want to find some information inside a web page and
display it in a custom way in your app.
This technique is called
“scraping.” Let’s also assume you’ve thought through alternatives to
scraping web pages from inside your app, and are pretty sure that’s
what you want to do.
Well then you get to the question – how can you
programmatically dig through the HTML and find the part you’re looking
for, in the most robust way possible? Believe it or not, regular
expressions won’t cut it!
And before you think Regular Expressions might really be an answer, please read this.
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 want to add a similar feature to a tool I'm making. I'm interested in how it works code-wise. I want to be able get an html page and exclude all but the article.
The Readability project does something similar for chrome and iOS. I'm not sure how it detects the content automatically but I know that Readability has an API for people who want to integrate it's features. You might want to check that out.

If you're working with Ruby, you could use Pismo. It extracts an article from a given document.
I would like to know on how wikipedia (http://en.wikipedia.org/) creates PDF? It seem to be using some application at the back-end. Could anyone please let me know on how this is done?
Thanks

Wikipedia runs Mediawiki.
A Google check tells me that they have two PDF extensions.
This one is the one who's still mantained: PDF_Writer
It doesn't use a PHP HTML→PDF generator, (though there are some)
It actually does something trickier and more clever.
The PDF Writer uses the Python Reportlab libraries to generate PDF based on a
DOM derived from parsing mediawiki-markup using the mwlib parser.
To confirm ZJR's answer, these are the document properties:
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.
