I would appreciate this technique if it will be supported as a general 
means.

The approach "srcML" uses the GPL. I guess that we'll need to look for a 
free class library with a different licence.

QVT and XQuery would also be nice applications for syntax trees.

The symbol lookup should be a component of a transformation step after 
the inital parsing with token decoration. Semantic analysis will be 
required for the conversion of an AST into an ASG representation.
