RE: How to pad space to a text node to make it have specfic lengt h?

[Nate Austin <naustin@xxxxxxxxxxxxxxx>]

Albert -
These are the templates I use to pad on the left or right with any character
passed in:

  <xsl:template name="prepend-pad">    <!-- recursive template to right
justify and prepend-->
                                       <!-- the value with whatever padChar
is passed in   -->
    <xsl:param name="padChar"> </xsl:param>
    <xsl:param name="padVar"/>
    <xsl:param name="length"/>
    <xsl:choose>
      <xsl:when test="string-length($padVar) &lt; $length">
        <xsl:call-template name="prepend-pad">
          <xsl:with-param name="padChar" select="$padChar"/>
          <xsl:with-param name="padVar" select="concat($padChar,$padVar)"/>
          <xsl:with-param name="length" select="$length"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="substring($padVar,string-length($padVar) -
$length + 1)"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

  <xsl:template name="append-pad">    <!-- recursive template to left
justify and append  -->
                                      <!-- the value with whatever padChar
is passed in   -->
    <xsl:param name="padChar"> </xsl:param>
    <xsl:param name="padVar"/>
    <xsl:param name="length"/>
    <xsl:choose>
      <xsl:when test="string-length($padVar) &lt; $length">
        <xsl:call-template name="append-pad">
          <xsl:with-param name="padChar" select="$padChar"/>
          <xsl:with-param name="padVar" select="concat($padVar,$padChar)"/>
          <xsl:with-param name="length" select="$length"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="substring($padVar,1,$length)"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

The 'padChar' param passed in could be as many characters as you want,
actually.  'padVar' is the variable to pad, and length is length, obviously.
Most of the XSLT I do is for fixed-length text files, and these haven't
failed me yet.

Hope this helps,
Nate
