This is a classic case for a lookup table either in your XSLT or in a separate document (where someone else might help to maintain it :-), accessed via the document() function.

See http://www.dpawson.co.uk/xsl/sect2/N4995.html for some hints, or search more broadly for "XSLT lookup tables".

The basic idea is that you construct a little XML that lists your values; you then traverse this list instead of your input to do your re-ordering. If you need to structure the list somehow, for example to group the values (as your sample suggests you might), this is easy enough to do (since it's XML). This also gives you a chance to generate something special when values in your list are not represented in your source file.

The code is more concise than the brute force method as well as easier to maintain, since both your list of values and their order are controlled as such, in one place.

I hope that helps,

Hi List,

Thanks in advance for the help. I think I left my brain in Cuba, and
cannot seem to figure out this fairly straight forward problem (well
that and secretly hoping someone has a more elegant way of doing

So I have a generated XML

 <name>Bar Archive</name>
 <name>Foo Archive</name>

Issue comes from the fact that every time I get this XML file, the
<view>s are in different, random order. I need them in a specific
order every time. Along with this, sometimes a <view> exists, and
sometimes it doesn't which should be reflected in the output. So far
my XSL looks something like this (I've marked where my if statement is

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">

<!-- This if statement fails (Value of expression cannot be converted
to a node-set in expression) -->
<xsl:if test="root//view/id = 'foo' | root//view/id = 'bar'">
 <p>Here are the foo bars</p>
 <xsl:apply-templates select="root//view[id='bar']"/>
 <xsl:apply-templates select="root//view[id='foo']"/>

<xsl:if test="contains(root//view/id, 'archive')">
       <p>Here are archive foo bars</p>
       <xsl:apply-templates select="root//view[id = 'bar_archive']"/>
       <xsl:apply-templates select="root//view[id = 'foo_archive']"/>



<xsl:template match="view" priority="5">
<li><xsl:value-of select="name"/></li>

<xsl:template match="view[contains(id, 'archive')]" priority="10">
<p><xsl:value-of select="name"/></p>


Any thoughts would be greatly appreciated. (PS - I am stuck with 1.0)

Thanks you,

Spencer Tickner
