Re: [xsl] Tokenize question: tokenize on words, spaces and

The main trick here seems to be simply constructing an appropriate
character class for each type of token and then matching sequences of
one or more of each.

The following does just that, though it also tosses in a twist to
handle words with embedded dashes, so that the dash won't break the
word into three separate tokens.  Further adjustments along those
lines may be needed, depending on your requirements.

The use of Unicode character categories for the character classes
should ensure that this works for most languages, I think, though
non-English languages aren't my strong suit, so I make no guarantees.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl=""
                version="2.0" xmlns:xs=""
                xmlns:f="urn:stylesheet-func" exclude-result-prefixes="xs f">
    <xsl:output method="text"/>
    <xsl:param name="s" select="'Oh, what a fun-filled day!'"/>
    <xsl:function name="f:tokens" as="xs:string*">
        <xsl:param name="string"/>
        <xsl:analyze-string select="$string"
    <xsl:template match="/">
        <xsl:value-of select="f:tokens($s)" separator="', '"/>
