unions, for-each, document order

[Steve Morrison <smorrison@xxxxxxx>]

So, I have a set of nodes each called <cat>. The <cat> tag has an attribute called level, which is either 0 or 1. The <cat>s come in alphabetical order, and ones with level="1" or level="0" can occur at any point. I need to process these in such a way that it applies a template to the level="1"'s first, then the level="0"'s. I then do another round of suppression/selection based on some other attributes.

This would do exactly what I want:
<xsl:for-each select="cat[@level = 1] | cat[@level = 0]">
  <xsl:if test="sometest based on parent nodes">
    <!-- create html -->
  </xsl:if>
</xsl:for-each>
except, the for-each and apply-templates goes in document order, as opposed to copy-of, which applies the union in the order I specify in the select! Is there another way around this? I tried using two different for-each loops, but, then that messes up my inner <xsl:if> test.

Thanks,
-Steve
