You can try something like this

  <xsl:for-each select="cd[recomondation='sell' or recomondation='rent' or recomondation='buy']">
    <xsl:copy-of select="."/>
  </xsl:for-each>

This will cause an iteration on all cd nodes whose child recommendation node contain your mentioned data. With your sample data currently only three nodes will be filtered out. If you are looking only for the recommendation nodes then you can try this

  <xsl:for-each select="cd//recomondation[.='sell' or .='rent' or .='buy']">
    <xsl:value-of select="."/>
  </xsl:for-each>
