Re: sort by xsl:if and then sort using templates?

xsl:sort have to be direct children of xsl:for-each (or
xsl:aply-templates) you can not nest in xsl:if (or anything else)
Just put the test on your select predicate or outside the xsl:apply-templates

It's a bit hard to show exactly what you need to do as I think you over
trimmed your stylesheet, but in general rather than


<xsl:apply-templates>
<xsl:if test="something">
<xsl:sort ..../>
</xsl:if>
</xsl:apply-templates>

do either

<xsl:apply-templates select="*[something]>
<xsl:sort.../>
</xsl:sort>

or 

<xsl:choose>
<xsl:when test="something">
<xsl:apply-templates>
<xsl:sort ..../>
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates/>
</xsl:otherwise>

depending on what you want to do if the predicate is false (no output,
or no sorting, respectively)
