Filtering with multiple templates

Hi,

I have a difficult situation here and try to get your
help.

There is the following XML:

<Member name="x">
  <Member name="y"/>
  <Member name="z">
      <Member name="z1"/>
      <Member name="z2"/>
  </Member>
  <Member name="w"/>
</Member>

We need to allow multiple templates to select some of
members. for example, 

the first template will get:
<Member name="x">
  <Member name="z"/>
</Member>

the second template will get:
<Member name="x">
  <Member name="w"/>
</Member>

If we run this two templates sequentially, we will
get:
<Member name="x">
  <Member name="z"/>
</Member>
<Member name="x">
  <Member name="w"/>
</Member>

But we want to get the following based on the original
structure:

<Member name="x">
  <Member name="z"/>
  <Member name="w"/>
</Member>

Please provide any idea that might help. Thanks a lot.
