That should be:
for (NSXMLNode *customerNode in customerArray) {
The for-in statement allows both variants. Using the first version:
NSArray *myArray = [NSArray arrayWithObjects:@"one", @"two",
@"three", @"four", nil];
NSString *testString = @"three";
NSString *myString = nil;
for (myString in myArray) {
if ([myString isEqualToString:testString])
break;
}
NSLog(@"myString = %@", myString);
testString = @"Five";
for (myString in myArray) {
if ([myString isEqualToString:testString])
break;
}
NSLog(@"myString = %@", myString);
myString will be valid outside of the for loop context and can be used
again. Also, if it finds the testString then myString will have the
found value. If the testString is not found then MyString will be nil.
