Close to trivial if you set up a key on the col-desc elements, I should
think. Maybe something like:
<xsl:key name="coldesc" match="col-desc" use="@num" />
...
<xsl:for-each select=" key('coldesc',@num)/@name = 'colname' " >
...
Alternatively you can get there using the parent and preceding-sibling
axes, but it's less clear.
