Re: Reverse Tokens Template

Hi Stephen,

This is a really easy task. Using FXSL one would write the following:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:vendor="urn:schemas-microsoft-com:xslt"
 exclude-result-prefixes="vendor"
>
 <xsl:import href="strSplit-to-Words.xsl"/>

 <xsl:output method="text"/>

  <xsl:template match="/">
    <xsl:variable name="vrtfWords">
      <xsl:call-template name="str-split-to-words">
        <xsl:with-param name="pStr" select="/*"/>
        <xsl:with-param name="pDelimiters" select="' ,.;&#9;&#10;'"/>
      </xsl:call-template>
    </xsl:variable>

    <xsl:for-each select="vendor:node-set($vrtfWords)/word">
      <xsl:sort select="position()" order="descending" data-type="number"/>
      <xsl:value-of select="."/>
      <xsl:if test="position() != last()">
        <xsl:text> </xsl:text>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>

When applied on this source.xml:

<t>Hello world</t>

the desired result is produced:

world Hello



Hope this helped.
