Following up on a converstation I had with Jarno and Dimitre.
This is a New York version of tokenize. (So good we did it twice)

General purpose tokenize, for known delimiters.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
exclude-result-prefixes="f">

  <xsl:import href="/sgml/fxsl/strSplit-to-Words.xsl"/>
<xsl:output method="xml"
encoding="UTF-8" indent="yes"/>

<xsl:template match="/vs">
 <xsl:value-of select="system-property('xsl:product-version')" />

  <xsl:apply-templates />
</xsl:template>

<xsl:variable name="xxx" select="//fld[1]"/>

  <xsl:template match="line">
    <xsl:call-template name="tokens">
        <xsl:with-param name="str" select="@event"/>
        <xsl:with-param name="splitString" select="' '"/>
      </xsl:call-template>
And using fxsl
       <xsl:call-template name="str-split-to-words">
        <xsl:with-param name="pStr" select="@event"/>
        <xsl:with-param name="pDelimiters" select="' '"/>
      </xsl:call-template>
    </xsl:template>


<xsl:template name="tokens">
  <xsl:param name="str" select="."/>
  <xsl:param name="splitString" select="' '"/>
  <xsl:choose>
    <xsl:when test="contains($str,$splitString)">
      <token>
      <xsl:value-of select="substring-before($str,$splitString)"/>
    </token>
    <xsl:call-template name="tokens">
      <xsl:with-param name="str"
select="substring-after($str,$splitString)"/>
      <xsl:with-param name="splitString" select="$splitString"/>
    </xsl:call-template>
  </xsl:when>
  <xsl:otherwise>
    <token><xsl:value-of select="$str"/></token>
  </xsl:otherwise>
</xsl:choose>
</xsl:template>


<xsl:template match="vs">
  <xsl:apply-templates/>
</xsl:template>


</xsl:stylesheet>


Input

<?xml version="1.0" ?>
  <vs>
    <line event="x y x">
    </line>


  </vs>


output

c:\sgml>type op.xml
<?xml version="1.0" encoding="UTF-8"?>

<token>x</token>
<token>y</token>
<token>x</token>
And using fxsl
       <word>x</word>
<word>y</word>
<word>x</word>
