[xsl] Template to return XML

["Karl J. Stubsjoen" <karl@xxxxxxxxxxxxx>]

Hello,

I need a template to return a subset of XML from the xml source.  I'm trying
to populate a variable with this information.  How can I do this?
Example:

<A>
    <B>
        <ASDF/>
        <QWEA/>
        <FEASI/>
    </B>
    <C/>
</A>


So, a template that will return (as an example) <B> and its subset of data.
Something like

<xsl:template name="get_subset_xml">
    .... select the <b> node
</xsl:template>

More importantly, how do I assign a variable to this new subset?
So:

<xsl:variable name="some_subset" select="get_subset_xml"/>

where $some_suset is:
    <B>
        <ASDF/>
        <QWEA/>
        <FEASI/>
    </B>


Is this possible?
Karl
