Hi All
I know there are always several ways to do things and have come across
something which puzzles me as to
the efficiency of these 2 ways of getting the same data from an
NSXMLNode object.
for this exercise assume theNode is an NSXMLNode object which has been
initialized and contains data and an attribute called class with
something in it.
Scenario 1
NSXMLElement *nodeAsElement = (NSXMLElement *)theNode;
NSString *attribContent = [[nodeAsElement attributeForName:@"class"]
stringValue];
NSLog(@"class contains %@",attribContent);
Scenario 2
NSString *attribContent = [[theNode objectsForXQuery:@"data(@class)"
error:nil] objectAtIndex:0];
NSLog(@"class contains %@",attribContent);
these will and do produce the same data but for my own personal
knowledge I would like to know which is more efficient.
I use both in my code but am leaning more towards the xquery style for
readability and maintainability of larger more nested structures.
Comments appreciated
