[xsl] Change of Attribute Value

["Miraodb" <miraodb@xxxxxxxxxxx>]

Hi all,

i have the following issue:
i want to change the value of attrivute on the fly. For example let's say i
have

<node name="ChrisW" description="Testmodel for WI/WE">
  <node_condition/>
  <node name="WE" description="">
    <node_condition/>
    <action/>
    <node name="ai" description="">
      <node_condition/>
      <action/>
      <node name="sub_ai" description="">
        <node_condition/>
        <action/>
      </node>
    </node>
    <node name="kgi" description="">
      <node_condition/>
      <action/>
      <node name="sub_kgi" description="">
        <node_condition/>
        <action/>
      </node>
    </node>
  </node>
  <node name="WI" description="">
    <node_condition/>
    <action/>
    <node name="ai" description="">
      <node_condition/>
      <action/>
    </node>
    <node name="kgi" description="">
      <node_condition/>
      <action/>
    </node>
  </node>
</node>



i want to have this after my xslt:

<node name="ChrisW" description="Testmodel for WI/WE">
  <node_condition/>
  <node name="WE" description="">
    <node_condition/>
    <action/>
    <node name="WE_ai" description="">
      <node_condition/>
      <action/>
      <node name="WE_sub_ai" description="">
        <node_condition/>
        <action/>
      </node>
    </node>
    <node name="WE_kgi" description="">
      <node_condition/>
      <action/>
      <node name="WE_sub_kgi" description="">
        <node_condition/>
        <action/>
      </node>
    </node>
  </node>
  <node name="WI" description="">
    <node_condition/>
    <action/>
    <node name="WI_ai" description="">
      <node_condition/>
      <action/>
    </node>
    <node name="WI_kgi" description="">
      <node_condition/>
      <action/>
    </node>
  </node>
</node>

so basically, i want to skip the first level of element <node>, and then
pick up the attribute @name value of the second level and concat it to all
sublevel attributes @name

I'm sure this is possible using some kind of recusion.
Any help, would be much appreciated.

Thanks in advance.
