How to do an XSL:for-each in reverse order

Question

I am looking to reverse in XSL/FO a for-each loop.

for instance the xml

Answer 1

Use xsl:sort not for ordering by @id but for ordering by position():

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/data">
    <xsl:for-each select="descendant-or-self::*/record">
        <xsl:sort select="position()" data-type="number" order="descending"/>
        <xsl:value-of select="@id"/>
    </xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Answer 2

xsl:sort is your friend ;

<xsl:for-each select="descendant-or-self::*/record">
   <xsl:sort select="@id" order="descending" />
   <xsl:value-of select="@id"/>
</xsl:for-each>

Answer 3

Yes, Alexander is right - forgot the data-type though:

<xsl:for-each select="descendant-or-self::*/record">
   <xsl:sort select="@id" order="descending" data-type="number" />
   <xsl:value-of select="@id"/>
</xsl:for-each>

(without that, you'll run into sorting problems with numbers over 9)
