mobi phil, Thanks ! I will use VisitStmt.
But I have another question:
   How to get namespace name of a  function ?
if this function is CXXMethodDecl, I  use CXXRecordDecl to get a NamespaceDecl  object, then I will get the namespace name.
if this function is a global function, I do not know howto.
