I have done xml parsing before using some guides from Ray Wenderlich, but those are usually for when there are multiple items involved. I am working on having an app simply display weather conditions at a given time, and the feed's XML just has conditions for time checked. Here is the feed in question:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<rss version="2.0" xmlns:yweather="http://xml.weather.yahoo.com/ns/rss/1.0" xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#">

Basically, all I need for the app is the current temperature and conditions, which under the item tag is contained within yweather:conditions tag. Using GDataXML, what would be simplest way of getting this info and setting an NSString equal to it?
Right now, I'm using some complex stuff from Ray's tutorial with asihttprequest and blocks for sorting and putting it all into an NSMutableArray, but I'm fairly certain it doesn't need be that complex now.
I like TBXML for straightforward parsing: http://www.tbxml.co.uk/TBXML/TBXML_Free.html .

I believe the 2 namespaces gd and gContact is not defined. I just added the namespaces and it seems good. Here is the modified XML with dummy namespaces (Please correct it accordingly),

I have an issue where I'm trying to host a podcast via RSS feed myself, and I'm running into a strange issue. I validated my RSS feed and all of that, got everything working on iTunes on the desktop just fine. However, when I go to play that same podcast on my iPhone, I either get a "podcast is temporarily unavailable" error, or nothing at all. All of the information shows up fine and everything, but nothing will play. I made sure to check with my hosting service that Byte Range Requests are supported, and enabled. I don't know what the problem could be. The RSS looks like this (I edited some personal information out):
<?xml version="1.0" encoding="UTF-8"?>
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

An option would be to use the NSXMLParser. I've used it with great success when parsing my RSS as well as ATOM feeds.
To examine information within <![CDATA[...]]>, you'll want to implement the following method of the NSXMLParserDelegate protocol:
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock
Here's a terrific tutorial to get you started: Parsing XML data with NSXMLParser
I'm studying Apple's LazyTableImages sample code. I'd like to understand how the app is pulling data from the RSS feed included in the app:
http://phobos.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/toppaidapplications/limit=75/xml
How are the contents at the above url parsed? Viewing the page source reveals HTML with no apparent xml section. While looking through the sample parsing code I found a few symbols like im:name. However these symbols are not in the contents of the above url.
I tried to host the contents of the above url locally (w/ limit=1). However pointing the sample code to #"~/Desktop/a.xml" causes the application to throw the error unsupported url.
More info: While reading http://en.wikipedia.org/wiki/Rss I came across what I expected to see at phobos link above. Something like this:
<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">

Is there an equivalent "human-readable" xml document corresponding to the above phobos link somewhere?
You're right, the feed you're looking at technically isn't an RSS Feed. It's an Atom 1.0 Feed, but both are popular XML-based feed formats.
If you view the source of the feed you will see the XML elements you're looking for, like:
<entry>
<updated>2011-12-09T16:15:32-07:00</updated>
<id>http://itunes.apple.com/us/app/tetris/id479943969?mt=8&uo=2</id>
<title>TETRIS® - Electronic Arts</title>
<summary>Long summary here</summary>
<im:name>TETRIS®</im:name>
...
</entry>
Some browser versions parse RSS/Atom feeds into user-friendly HTML pages and present them instead of the actual feed, it sounds like that's the type of HTML page you're viewing.
On a OS X, you could use a command like Curl to download the feed in a Terminal:
curl -o feed.xml http://phobos.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/toppaidapplications/limit=75/xml
I'm using rails and the Nokogiri parser. My xml is as below and I'm trying to get the 'Biology: 08:00' text into my view.
<rss version="2.0">
<channel>
<item>
<title>Biology: 08:00</title>
<description>Start time of Biology</description>
<pubDate>Tue, 13 Oct 2009 UT</pubDate>
</item>
</channel>
</rss>
I can find the node with the text 'biology' using the code below
#content = doc.xpath('//title[contains(text(),"Biology")]')
When I move it into my view it strangely ends up as the title of my .html.erb page. I can't seem to get it into the body with
<body>
<%=#content%>
</body>
anyone know what's going on?
You're getting the whole node, and the node is a <title> tag.
you want:
#content = doc.xpath('//title[contains(text(),"Biology")]/text()')
to get the text content of the node
