[cfe-dev] Iterating through an Expression in the Clang AST

[beni]

Hi,

I want to iterate through an Expression while visiting the nodes in the
Clang AST. Using the function VisitExpr(),
I am able to visit various expressions, but I wish to find sub expessions
for analysis.

Eg. given an expression: 3+A+B, I wish to iterate through this expression
and visit 3,A and B.

Does anyone have any idea how this can be done?

Thanks
