<!--
  Here is how I am wrapping text via XSLT as opposed to CSS and JavaScript. The reason why I am prefering to do this
  server side via XSLT as opposed to JavaScript client-side is because if I will be doing client-side JavaScripts,
  I would have to escape the stuff during the HTML generation anyway in XSLT server-side. So in the same processing
  power I might as well wrap it instead. Of course you can also do it via some fancy JavaScript client side by going
  through the entire table and chopping up the text in each row, but that would make things look rather interesting
  to the user (tables automatically re-arranging themselves).
  
  Anyway, here is a simple recursive template based on the code posted by Andrew Welch:

<xsl:template name="text_wrapper"> 
<xsl:param name="text"/> 
<xsl:param name="width" select="20"/> 

<xsl:if test="string-length($text)"> 
  <xsl:value-of select="substring($text, 1, $width)"/><br/> 
  <xsl:call-template name="text_wrapper"> 
    <xsl:with-param name="text" 
     select="substring($text, $width + 1)"/> 
    <xsl:with-param name="width" select="$width"/> 
  </xsl:call-template> 
</xsl:if> 
</xsl:template>

<!-- To use it, call it as follows: -->
<xsl:call-template name="text_wrapper"> 
  <xsl:with-param name="text" select="sometext"/> 
  <xsl:with-param name="width" select="20"/> 
</xsl:call-template>
