You need to post you xml sample as a code block - in the example shown above all xml tags got stripped! — Shirkrin, Oct 01 '09 at 06:51
`CourseGradePercentage` should be `GradePercentage`. `AssignmentGradePercentage` should be `GradePercentage`. Notice that you can then reuse the same code for parsing. And Week 1 is also redundant. You could just have 1. Better yet would be . — Dave Jarvis, Oct 01 '09 at 22:20

Consider using libxml2 with an Objective-C front provided by this useful set of wrapper functions.

You issue an XPath query to your XML document object and get back Foundation class objects: NSArray, NSString, and NSDictionary, e.g.:

//
// Generate NSData* object called _xmlData which is the XML data
// 

// ...

//
// Query this data for course names
//

NSArray *_queriedCourseNames = PerformXMLXPathQuery(_xmlData, @"//*[local-name()='Course']/*[local-name()='CourseName']");

Instead of 'Course,' why do you want to use local-name?

//Course/CourseName

should just work, right?
