Assuming that you do just want to concatenate these, then the reason the
last group was being split was that I was looking for a trailing comma,
so if you add a comma to the end of the list so it looks like
<xsl:variable name="str"
select="'aaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,'"
as="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
<xsl:variable name="length" select="255" as="xs:integer"
xmlns:xs="http://www.w3.org/2001/XMLSchema"/>
Then the following works (just added [string()] to get rid of the empty
token that (now) comes after the trailing comma)
<xsl:for-each
select="tokenize(replace($str,concat('(.{0,',$length,'}),'),'$1!'),'!')[string()]">
<words><xsl:value-of select="."/></words>
</xsl:for-each>
Of course if your input is really a set of word elements and not a
comma separated list there is no point in joining then up and splitting
them, really.
