XPATH: Filtering (rather than selecting nodes), preserving hierarachy - xpath-2.0

Question

Given the following XML (with many hierarchy levels), I need to return the nodes after filtering all nodes with Hide"True" attribute and a certain name. Note that hide could be at any hierarchy level:
<items>
<item id="1" >
<item id="2" />
<item id="3" />
<item id="4" hide="true"/>
</item>
<item id="5" hide="true">
<item id="6" >
<item id="7">
<item id="8" hide="true"/>
<item id="9"/>
</item>
</item>
</items>
I would need to get this back:
<items>
<item id="1"">
<item id="2" />
<item id="3" />
</item>
<item id="6" >
<item id="7">
<item id="9"/>
</item>
</item>
</items>
The 'filtered' XML is then assigned to a treeview, so I need to preserve the hierarchical nature of the nodes. I have tried: "items//item[#hide='false' or not(#hide)]", but this returns a flattened (as well as duplicative) data, repeating nodes at the lower level pushed up to the top level as follows. Is there a way to use Xpath to do what I want? I understand that I can Xslt the data first, then display it, but it just seems that there is got to be an easier way. I am using c#/.net4.0 MSXML
<items>
<item id="1"">
<item id="2" />
<item id="3" />
</item>
<item id="6" >
<item id="7">
<item id="9"/>
</item>
</item>
<item id="2" />
<item id="3" />
<item id="7">
<item id="9"/>
</item>
<item id="9"/>
</items>
