Re:  Please look at my mini-template

if you do not want to directly output the converted hex string as David
pointed out
a more comprehensive solution is using a func:function:

<xsl:stylesheet version="1.0"
  <xsl:output method="xml" />

  <xsl:template match="/hex2path">
    <xsl:value-of select="ns:hex2path(.)" />

  <func:function name="ns:hex2path">
    <xsl:param name="str" />
      <xsl:when test="(string-length($str) &gt; 2)">
        <func:result select="concat(substring($str, 1, 2), '/',
                             ns:hex2path(substring($str, 3)))" />
        <func:result select="$str" />

             Please respond to          Please look at my
             xsl-list@xxxxxxxx         mini-template


I needed this functionality:
Given the input of a HEX number (example 2A32BF42)
I needed to split the string in such a way that a '/' is inserted
after every 2 characters except that
the '/' should NOT be added at the end of string.

So 2A32BF42 has to become 2A/32/BF/42

This had to be done in XSLT 1 because its for browser-based

I wrote a template for this and want to hear the opinion of the
experts. I just started learning XSLT about a week ago.
So what do you think?

Here it is:

<xsl:template name="hex2path">
        <xsl:param name="left" select="''"/>
        <xsl:param name="right"/>
            <xsl:when test="(string-length($right) > 2)">

                <xsl:call-template name="hex2path">
                    <xsl:with-param name="left">
                        <xsl:value-of select="concat($left,
concat(substring($right, 1, 2), '/'))"/>

<xsl:with-param name="right">

<xsl:value-of select="substring($right, 3)"/>


                <xsl:value-of select="concat($left, $right)"/>
