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 have a project from my lecture to create a web apps to read and analyze a pdf file based on keywords. What kind of programming language that I can use?
Example : I need to find or check some keywords or data on the pdf file. If the keyword or data is exist and available, the result is true.
I usually work in javascript so could answer you in that, I had a great help from the below conversation, it might be a good help for you too.

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,

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 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.

I am new to iPad programming. Can anybody tell me how to convert xml file to html file using xslt in iPad . I have read other posts related to this question but i am not able to get the proper answer. Do i have to use any library for it, how to import these file to my objective c code and how to process it.
Thanks in advance.
Check this question it has a similar discussion which might help you to explore more,
