Subject:  Keeping track of parents


Hi there,

I'm a newbie, so please be patient with me if I cannot explain my problem
as I should. I am quite stumped on this.

This is my problem:

I have an XML-File with a structure like this (simplified):

<somenode id="1">
  <more_elements/>
  <somenode id="2">
    <more_elements/>
    <somenode id="3">
      <more_elements/>
    </somenode>
  <somenode id="4">
    <more_elements/>
  </somenode>
</somenode>

That is, the element <somenode> can have children that are also called
<somenode>.

My result xml should look like this:

<structure>
  <group_name value="some_value_from_more_elements"/>
  <group_id value="some_unique_id_for_somenode"/>
  <parent_id value="group_id_of_somenodes_parent"/>
</structure>
<structure>
  <group_name value="some_value_from_more_elements"/>
  <group_id value="some_unique_id"/>
  <parent_id value="group_id_of_somenodes_parent"/>
</structure>
<structure>
  <group_name value="some_value_from_more_elements"/>
  <group_id value="some_unique_id"/>
  <parent_id value="group_id_of_somenodes_parent"/>
</structure>
<structure>
  <group_name value="some_value_from_more_elements"/>
  <group_id value="some_unique_id"/>
  <parent_id value="group_id_of_somenodes_parent"/>
</structure>

Most of it I can generate, but how can I fill the parentid? If there is no
ancestor-element named <somenode> then the parent_id should be 0, else the
parent_id should be the group_id of the ancestor.

If it matters: I'm using xalan.

Thanks for helping me,
Christian
