Hi Andrew,

let me try what came to mind second ;)
Here's my go on it in a single XPath statement. A bit less well-suited for educational purposes. It shows nested for-loops in XPath, casting, use of sequences+separator and some ways how not to code (it is exactly an example of good programming practice ;)

<xsl:stylesheet version="2.0"
<xsl:output method="text" />
<xsl:template match="/" name="main">
<xsl:value-of select="
for $i in reverse(1 to 99)
return for $j in
(' on the wall.',
'.&#10;Take one down, pass it around',
' on the wall.&#10;' )
return concat
($i - xs:integer(ends-with($j, '&#10;')),
' bottle', if ($i = 1) then '' else 's',
' of beer', $j)
" separator="&#10;"/>
