Re: String Manipulation in XSL

I was wondering if anyone had a solution for this problem.  I get an element
through which has a string which can be variable length.  It could be 20
characters long, 40, 60, upto anything really.

I'm wanting to put in a space every 20 characters, and am unsure on how to
do this.

T:\ftemp>type peter.xml
<?xml version="1.0" encoding="utf-8"?>
<value>12345678901234567890123456789012345678901234567</value>
T:\ftemp>type peter.xsl
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="/">
  <xsl:call-template name="do-a-string">
    <xsl:with-param name="string" select="/value"/>
  </xsl:call-template>
</xsl:template>

<xsl:template name="do-a-string">
  <xsl:param name="string"/>
  <xsl:if test="$string">
    <xsl:value-of select="substring($string,1,20)"/>
    <xsl:text> </xsl:text>
    <xsl:call-template name="do-a-string">
      <xsl:with-param name="string" select="substring($string,21)"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>
