XSLT 2.0: What's better, an example.

In XSLT 1.0:

<xsl:template match="@one-of" name="parse-one-of">
  <xsl:param name="list" select="string(.)" />
  <xsl:if test="$list">
    <xsl:variable name="value"
      select="substring-before($list, '|')" />
    ...
    <!-- do something with $value -->
    ...
    <!-- recursive call -->
    <xsl:call-template name="parse-one-of">
      <xsl:with-param name="list"
        select="substring-after($list, '|')" />
    </xsl:call-template>
  </xsl:if>
</xsl:template>

In XSLT 2.0:

<xsl:for-each select="tokenize(@one-of, '|')">
	<!-- do something with . -->
</xsl:for-each>
