Hi Norbert: Alas, I am laboring under the burden of being a newbie to both Pharo and XML. It seems to me that it would be better to be able to dynamically pick up all of the child elements of an element of interest, however, I can't imagine how to define an object that doesn't know it's own contents until run-time. In addition, in my case, some of the child elements are complex (i.e. they also contain children) which complicates the traversal a little bit. I'm assuming for now that I will have to read the source XML, define the instance variables of my object based on them, and simply populate them at run time by traversing the XML tree. If the XML model changes, the object definition will have to change too.
