do you mean that you want to re-parse it upon clicking a button?
In that tutorial is the section:
Code:
//Start parsing the XML file.
BOOL success = [xmlParser parse];
if(success)
NSLog(@"No Errors");
else
NSLog(@"Error Error Error!!!");
so I believe you just need to have that be your button code, after editing it slightly to point to the right place:
Code:
BOOL success = [appDelegate.xmlParser parse];
(after defining appDelegate for your particular app)
