If you want get_subset_xml to return the *source nodes*, that isn't possible with XSLT 1.0. You can create a copy of the nodes and return that as a RTF.

  <xsl:variable name="some_subset" select="/A/descendant::*"/>

but it's more than likely you want

  <xsl:variable name="some_subset" select="/A/B"/>

as the former the variable is bound to a set of nodes B, ASDF, QWEA, and FEASI, whereas in the latter it's bound to just the B node and you can access the child nodes by normal tree navigation.
