You would normally need a data binding tool to be able to do this.
Generic XML parsers such as libxml2 represent information stored
in an XML document as a set of elements, attributes and text. The
advantage of this approach is that it can handle pretty much any
(valid) XML instance. The disadvantage lies in the fact that you
have to go through this raw XML representation and convert it to
your application data types (e.g., text to integers).

A data binding compiler will automatically generate data types
and conversion code for your vocabulary from XML Schema (or other
schema languages). This way you can access the data stored in XML
using types and functions that semantically correspond to your
application domain rather than dealing with elements, attributes
and text.
