Let's say I have XML data that I just downloaded from a web app api.
How do I parse the data?
How do I populate each cell of a table view with this data?
Here is a tutorial that does exactly what you are asking for. It downloads an RSS feed (which is XML), parses it, then loads the data into a table.
It should be easy to modify this for your application.

You may use one of the DOM XML parsers, like GData, KissXML or TouchXML +
XPath API (all 3 seems to support it) to extract your data.

I'm using an NSXMLParser to read data out of a XML, but how can I make my iPhone App storing data into this specific XML.
The case is that I want to create an app to display available dates and one that administrates this dates, whether they are available or not (I'm using an UISwitch to handle this).
Thanks for your answers,

If you have small amount of data, you can save them in a plist.
See Property List Programming Guide
There's a github project that let's you create XML DOM objects. You can save your XML to your documents folder on the phone.

I have seen some tutorials on the subject, but they all go half into it and then leave a person wondering.
How can I stream an rss feed into an iphone app.
I know the xml should be read in, parsed etc.
But then I am not sure how to display the information I need like, images, embedded videos etc.
If someone could just point me in the right direction I would be extremely grateful.
Thanks in advance
First, you need some type of XML parser. You can use the built in NSXMLParser or a slew of other parsers that you will need to download. Each have their pros/cons depending on what type of reading/writing you will be doing with your RSS feed.
To display the data, I would recommend a tableView. You can create custom UITablvewCells for each cell to hold the data however you want to display it. There are several tutorials available for that if you want to Google for it.
As for data, read all the RSS data into an array you create and have the tableView access that array.
Again, there are many online tutorials for this already but it seems like you need help with displaying the data. A quick Google lookup for how to create custom UITableViewCells should provide you lots of helpful links. Good luck.
