Output of syntax anlayzer is not like parse tree that chapter 11 expected?

[Henoktes722]

I completed project 10 successfully.
I tried a let statement with expression "x + g(2, y, -z) - 5", and outputs like this one. But When I read chapter 11 It says the syntax analyzer output is like this one,



But my compiler output is not like the parse tree, I think I miss a concept.

<expression>
  <term>
   <identifier> x </identifier>
  </term>
  <symbol> + </symbol>
  <term>
   <identifier> g </identifier>
   <symbol> ( </symbol>
   <expressionList>
   <expression>
   <term>
   <integerConstant> 2 </integerConstant>

   <symbol> , </symbol>
   <expression>
