Yes, but you don't need to know where in the hierarchy they are and
what they are, only that they have a get_text method. It could
even be possible later to overload that.

Also, I'm thinking of including some scripting language ability 
in the XML file: if it were possible to do small Perl / TCL / whatever
scripts, it would be possible to send the C part an array of springs
processed in whatever way desired. The only problem would be the introduced
language dependency of the XML files (we don't want another VRML 
Java/JavaScript fiasco...)
