Recursive nested elements woe

Hi every-one,

(Deleted and reposted to avoid sp@m)

I have an XML file that looks like this:

_____________________________XML__________________ _______________

<root>
<nextlevel>
<init>
<element1>
Content
</element1>
<element2>
More content
</element2>
...etc
<message>
<element1>
Content
</element1>
<element2>
More content
</element2>
...etc
<message>
<element1>
Content
</element1>
<element2>
More content
</element2>
...etc
</message>
</message>
</init>
</nextlevel>
</root>

__________________________________________________ _______________

The <message> nodes may well contain other <message> nodes which could
contain other <message> nodes etc. etc. ad infinitum(well, almost!)

My problem is that when it comes to the XSL, I want to nest these nodes
and indent them and this is what I have so far:

_____________________________XSL__________________ _______________
<xsl:template match="/">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>

<xsl:template match="init">
<xsl:value-of select="element1"/>
<xsl:value-of select="element2"/><br />
</xsl:template>

<xsl:template name ="message" match="message">
<blockquote>
<xsl:value-of select="element1"/>
<xsl:value-of select="element2"/>
<xsl:for-each select="message[count(descendant::message)!='0']">
<xsl:call-template name="message"/>
</xsl:for-each>
</blockquote>
</xsl:template>

__________________________________________________ _______________

However, this only nests up to and including the second <message> node
and no further. Any help appreciated :)

Tom.

That's nice and simple!
My solutions tend to get more and more complicated :)
How would I now go about adding some formatting to the element1 &
element2 content?

Thanks for your help, it's very much appreciated.

That's lovely and simple, my efforts get recursively more complicated ;)
Thanks for your help.

Tom,
Wouldn't it be better/simplier to do the recursion with the normal
xsl:apply-templates like so.

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

<xsl:template match="root">
<html>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>

<xsl:template match="init|nextlevel">
<xsl:apply-templates/>
</xsl:template>

<xsl:template match="element1|element2">
<xsl:value-of select="."/>
</xsl:template>

<xsl:template match="message">
<blockquote>
<xsl:apply-templates/>
</blockquote>
</xsl:template>
</xsl:stylesheet>
===================================
Is this what you were looking for?
