You can put a constructed sub-tree in a variable:

<xsl:variable name="t">

and then do further transformations on the content of this variable

<xsl:apply-templates select="$t" mode="post-process"/>

If you're still using the old XSLT 1.0 version, there are restrictions on
using variables this way, which (with most processors) you can get around with
an extension function:

<xsl:apply-templates select="exsl:node-set($t)" mode="post-process"/>

> Now I would like to modify the style of the details_table depending on the
outcome of the test within the for-each loop. Since the table element has
already been created, I do not know how one could do this without changing the
overall logic. Is there a way to access the elements of the created HTML DOM
tree from within the stylesheet? Or am I hunting in the wrong direction?!
