This is a FAQ: http://www.dpawson.co.uk/xsl/sect2/repetition.html

Replace the javascript function with a named template like this:

<xsl:template name="makeTreePath">
  <xsl:param name="n"/>
  <xsl:if test="number($n) > 0">
    <xsl:text>|---</xsl:text>
    <xsl:call-template name="makeTreePath">
      <xsl:with-param name="n" select="number($n) - 1"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>

and call it like this:

<xsl:if test="@Level">  
      <xsl:call-template name="makeTreePath">
		<xsl:with-param name="n" select="@Level"/>
	</xsl:call-template>
</xsl:if>

Cheers!
