Hi,

again I have Java AST which is created from

public class Test  {
     String o = new String("hh");
     public void wrong1() {
       synchronized(o) {
             // huhu
      }
   }
}

I try to create a XPath query which finds the synchronized block in which the defined String variable o is used.

As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working

//SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]]

I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part.

Hope its clear what i mean ;-)

Thanks
