Read XML attributes in libxml SAX parser

Adding following lines in startElementSAXFunc method, and we can use attributes string keys and values as following.

for (int i = 0; i < nb_attributes; i++) {
    NSString *key = [[NSString alloc] initWithCString:(char*)attributes[0] 
                                             encoding:NSUTF8StringEncoding];
    NSString *value = [[NSString alloc] initWithCString:(char*)attributes[3] 
                                                 length:attributes[4] - attributes[3]]; 

    NSLog(@"%@ = %@", key, value);

    [key release];
    [value release];

    attributes += 5;
}
