If you don't want to use doe you could use these templates:

  <xsl:template match="description">
    <xsl:copy>
      <xsl:call-template name="parse"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template name="parse">
    <xsl:param name="str" select="."/>
    <xsl:choose>
      <xsl:when test="contains($str,'&lt;')">
        <xsl:variable name="tag"
select="substring-before(substring-after($str,'&lt;'),'&gt;')"/>
        <xsl:variable name="endTag">
          <xsl:choose>
            <xsl:when test="contains($tag,' ')">
              <xsl:value-of select="substring-before($tag,' ')"/>
            </xsl:when>
            <xsl:otherwise>
              <xsl:value-of select="$tag"/>
            </xsl:otherwise>
          </xsl:choose>
        </xsl:variable>
        <xsl:call-template name="parse">
          <xsl:with-param name="str"
select="substring-before($str,concat('&lt;',$tag,'&gt;'))"/>
        </xsl:call-template>
        <xsl:call-template name="parseTag">
          <xsl:with-param name="tag" select="$tag"/>
          <xsl:with-param name="endTag" select="normalize-space($endTag)"/>
