I am currently using a two-step process to sort a list of cross references in
an FO file. I run the pub through my XSL-FO style sheets, then run my resultant
FO file through a second XSLT (FO to FO) to sort the results of resolved cross
references.
I have a list of cross references the looks like this:

Currently I run a second XSLT (below> to sort the FO output.
<xsl:template match="fo:block[@role='REFERENCES']">
<fo:block widows="2" orphans="2" space-before.minimum="6pt"
space-before.optimum="7pt" space-before.maximum="8pt" space-after.minimum="0pt"
space-after.optimum="0pt" space-after.maximum="1pt" span="none"
role="REFERENCES">
<xsl:copy-of select="child::fo:block[1]"/>
<xsl:apply-templates select="child::fo:block[position() >
1]">
<xsl:sort
select="substring-after(fo:basic-link/text(),'WP')"/>
</xsl:apply-templates>
</fo:block>
</xsl:template>
Instead of running the second XSLT, I want to perform the sort with the initial
style sheet run. I know I can capture the unsorted output into a variable, but
where I'm having trouble is sorting the contents (value) of the variable and
then writing out the sorted output. What I have so far (and this is just a
snippet of a much larger XSL-FO style sheet of nearly 80 modules).
<xsl:template match="ref">
<fo:block space-before.maximum="8pt" space-before.minimum="6pt"
space-before.optimum="7pt" span="none" xsl:use-attribute-sets="wpinfosub">
<fo:block font-weight="bold"
keep-with-next.within-column="always">
<xsl:text>References</xsl:text>
</fo:block>
<xsl:variable name="REFS">
<xsl:apply-templates
select="child::ref-setup-item"/>
</xsl:variable>
<xsl:apply-templates select="$REFS">
<xsl:sort
select="substring-after(child::basic-link/text(),'WP')"/>
</xsl:apply-templates>
</fo:block>
</xsl:template>
The above does not work. I do know that the value of $REFS is correct in that
I've used <xsl-copy-of select="$REFS" to verify the value or contents of $REFS.
How I do sort the value of $REFS and put it into the output? Using the above is
outputting the <fo:root> and <fo:layout-master-set>, then "value-of" (just
text) $REFs with no FO markup. What am I missing?
