How to extract certain data from XML

Question

In Xcode I have been able to parse an xml document so it shows:
description=...
name=...
Now I need to extract just the description aspect of it or just the name.
How do I do this?
Thanks in advance.

I'm just trying to get you to meet me halfway. I'm shooting in the dark here. Oh well, here goes nuthin'. Everybody better duck...
Suppose you have the following XML file:
<data>
<name>John</name>
<description>Hapless programmer</description>
<status>exasperated</status>
</data>
From the example code in that library:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"someFile" ofType:@"xml"];
NSDictionary *xmlDoc = [NSDictionary dictionaryWithXMLFile:filePath];
If you want to get the name, description, and status into separate strings, you would do something like this:
NSString * name = xmlDoc[@"name"];
NSString * description = xmlDoc[@"description"];
NSString * status = xmlDoc[@"status"];
Don't you dare ask me how it would look in Swift.
