Using Eclise JDT, I need to retrieve the children of any AstNode. Is there a utility method somewhere that I could use ?

The only way I can think of right now is to subclass AstVisitor and treat each kind of node manually to find its children. But it's a lot of work to study every node type.

hi you should ask this question on JDT (Java Development Tools) group, not on PDT (PHP Development Tools) group.

Implementing ASTVisitor interface is the way to go. You could have a look at other's implementations of ASTVisitors by finding out that class (Ctrl+Shift+T and enter "ASTVistor) and then searching all it's subtypes (Ctrl+T).
In PDT's ASTVisitor we have convenience method ASTVisitor.visitGeneral(ASTNode) that is being called for every node. Not sure if that's the same for JDT AST though...
