XST String Reverse

[dumpy31dec]

I have a string value in a node of a xml file.
For example:a/b/c/d.
By using XSLT i need to chane the string in a reverse order.
For Example: d/c/b/a.
How to do this please help its urgent.

after a while of thinking, this came to my mind:

// <xsl:param name="input" select="--get-text-here--"/>
<xsl:param name="result"></xsl:param>
<xsl:param name="pos" select="string-length($input)"/>
 
<xsl:template name="xyz">
  <xsl:param name="result" select="concat($result, substring($input, $pos, 1))"/>
  <xsl:param name="pos" select="$pos - 1"/>
  <xsl:if test="$pos gt; 0">
    <xsl:call-template name="xyz"/>
  </xsl:if>
</xsl:template>

I didn't check it (had no time), maybe you have to use <xsl:with-param>. at least this should get you started.

Reduce the string one letter at a time. Then output from the back. As the template calls come back, the string will start outputting from the back first.

<xsl:call-template name="xyz">
  <xsl:with-param name="input" select="."/><!-- change xpath here -->
</xsl:call-template>
 
 
<xsl:template name="xyz"> 
  <xsl:param name="input"/>
  <xsl:if test="string-length($input) &gt; 0">
    <xsl:call-template name="xyz"> 
      <xsl:with-param name="input" select="substring($input, 2)"/>
    </xsl:call-template>
    <xsl:value-of select="substring($input, 1, 1)">
  </xsl:if>
</xsl:template>
