I am trying to parse students from an xml file and display them in a tableview. Then, when you click on a student listed in the tableview, it will display the students details in a separate view controller. The xml consists of multiple courses, with each course having multiple students. Below is an example of the xml which consists if the courses Graphics and Photography:\[code\]<Course> <Graphics> <Student> Student Info in here </Student> ... </Graphics> <Photo> <Student> Student Info in here </Student> ... </Photo></Course>\[/code\]I am fairly new to Xcode, but i have read some tutorials on using Xcode and parsing data from an xml file. Below is what i have written in my project to retrieve the student data from the xml file:\[code\]-(void) parser

But I just want to display the students who do Graphics.I am just wondering is there a way that i can display the students from a chosen course, without displaying the students from the other courses?
