<xsl:for-each select="row">
  <xsl:sort select="column[$sortcol]"/>
  <!-- rows sorted by the $sortcol'th <column/> -->
</xsl:for-each>

Is there any way to sort using <xsl:sort> for a positional sort?
For instance, given the following XML for a generic table, is there
a way to specify to sort the rows by the first or second column, depending
on which column is chosen to sort by?

<?xml version="1.0" encoding="ISO-8859-1"?>
<table> <row>
<column>x</column>
<column>b</column>
</row>
<row>
<column>z</column>
<column>c</column>
</row>
<row>
<column>y</column>
<column>a</column>
</row>
</table>
