saving nodes for later output

I'm not sure how to go about this so here is my qeustion:

I have markup which represents a table and inside the table are footnotes
and footnote references. I want to save the footnotes (body) outside of the
table.

So with this:
<tab>
 <row>
  <cell id="1">Text with a footnote.<footnote-ref
fnref="1.1"><sup>*</sup></footnote-ref></cell>
  <cell id ="2">More text...</cell>
 </row>
 <row><cell id="3">&nbsp;</cell></row>
 <row><cell id="4">&nbsp;</cell></row>
 <row>
  <cell id="5">
   <footnote-body fn="1.1">This is the text referred to in cell
id="1"</footnote-body>
  </cell>
 </row>

I'd like this (I'll use HTML as an example):
<table>
 <tr>
  <td>Text with a footnote.<a href="#1.1"><sup>*</sup></a></td>
  <td>More text...</td>
 <tr><td>&nbsp;</td></tr>
 <tr><td>&nbsp;</td></tr>
</table>
<p><a name="1.1">*</a>This is the text referred to in cell id="1"</p>
