Like most things you'd accomplish with loops in traditional languages, 
this can be done in XSLT with recursion and named templates. Here's a 
simple stylesheet that prints 100 dots.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output  indent="yes"/>

  <xsl:template match="/">
    <xsl:call-template name="dots">
      <xsl:with-param name="count">100</xsl:with-param>
    </xsl:call-template>
 </xsl:template>

  <xsl:template name="dots">

      <xsl:param name="count" select="1"/>

        <xsl:if test="$count &gt; 0">
          <xsl:text>.</xsl:text>
          <xsl:call-template name="dots">
            <xsl:with-param name="count" select="$count -1"/>
          </xsl:call-template>
        </xsl:if>

  </xsl:template>


</xsl:stylesheet>


Obviously if you could call the dots template with the count param set 
to a value provided by the input document rather than a constant as seen 
here.
