Selecting from xml specifying an order
Question
using xslt 1.0 on python, I am trying to select a few items while specifying order:
<?xml version="1.0" encoding="UTF-8"?>
<items>
<item name='1'>
first
</item>
<item name='2'>
second
</item>
<item name='3'>
third
</item>
</items>
If I use a for-each with a big OR'd together list, I can get the items I want, but only in the original order of the xml source document above.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<xsl:for-each select="items/item[@name='2']|items/item[@name='1']">
<p>hi</p>
<xsl:value-of select="." />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
This produces:
hi
first
hi
second
But I would like to have it output:
hi
second
hi
first
I think using xsl:apply-templates might be the way to go, but I can't get it to work with even this simple example. What is the best way in xslt 1.0 to select elements in a specific order?

You can use <xsl:sort> to specify ordering especially when there is a specific logic to define the ordering , for example to order by name attribute value in descending order :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<body>
<xsl:for-each select="items/item[@name='2' or @name='1']">
<xsl:sort select="@name" data-type="number" order="descending"/>
<p>hi</p>
<xsl:value-of select="."/>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
"I think using xsl:apply-templates might be the way to go, but I can't get it to work with even this simple example"
That's also possible, for example :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates select="items/item[@name='2']"/>
<xsl:apply-templates select="items/item[@name='1']"/>
</body>
</html>
</xsl:template>
<xsl:template match="items/item">
<p>hi</p>
<xsl:value-of select="."/>
</xsl:template>
</xsl:stylesheet>
output :
<html>
<body>
<p>hi</p>
second
<p>hi</p>
first
</body>
</html>
