Let's say I have the following structure:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<child id="c1">
<child id="gc1">
<child id="ggc1"/>
<child id="ggc2"/>
</child>
<child id="gc2">
<child id="ggc3"/>
<child id="ggc4"/>
</child>
</child>
<child id="c2">
<child id="gc3">
<child id="ggc5"/>
<child id="ggc6"/>
</child>
<child id="gc4">
<child id="ggc7"/>
<child id="ggc8"/>
</child>
</child>
</root>

By using the following XPath query

//child[@id="gc3"]/child

I can get the child nodes of "gc1". But what I'd really like to get
is the sub branch/path going back to the root. So instead of just
returning the two nodes

<child id="ggc5"/>
<child id="ggc6"/>

I'd like to be able to return the sub branch/path

<root>
<child id="c2">
<child id="gc3">
<child id="ggc5"/>
<child id="ggc6"/>
</child>
</child>
</root>

Is that possible? Or is this something I'd have to do programatically
using the nodes returned by the XPath query? Basically, I'm just
trying to get a fragment of the larger xml document...

thnx,
Christoph
