thanks,
You can do "searching" of arrays using predicates, like so:
NSMutableArray* names = [NSMutableArray arrayWithObjects:@"Andy", @"Bart", @"Bob", nil];
NSPredicate* predicate = [NSPredicate predicateWithFormat:@"SELF beginswith[c] 'b'"];
NSArray* namesStartingWithB = [names filteredArrayUsingPredicate: predicate];
// namesStartingWithB now contains @"Bart" & @"Bob"
You should look at the NSArray and NSPredicate documentation for more information. If you're after information specific to parsing XML (i.e. an RSS feed), you should check out Matt Gallagher's article on using libxml2 for XML parsing and XPath queries in Cocoa.
