If there are xml elements with same name and they are changed only from their id like below,

<parents name='Parents'>

  <Parent id='1' name='Parent_1'>

    <Children name='Children'>

      <child name='Child_2' id='2'>child2_Parent_1</child>

      <child name='Child_4' id='4'>child4_Parent_1</child>

      <child name='Child_1' id='3'>child1_Parent_1</child>

      <child name='Child_3' id='1'>child3_Parent_1</child>

    </Children>

  </Parent>

  <Parent id='2' name='Parent_2'>

    <Children name='Children'>

      <child name='Child_1' id='8'>child1_parent2</child>

      <child name='Child_2' id='7'>child2_parent2</child>

      <child name='Child_4' id='6'>child4_parent2</child>

      <child name='Child_3' id='5'>child3_parent2</child>

    </Children>

  </Parent>

</parents>

If you want to extract any child note from parent node using id, please follow like below mentioned,

//Parent[@id='1']/Children/child[@name] 

Then output will like below,

Child_2

Child_4

Child_1

Child_3
