Sorry. Here it is.

XML:

<ming>

  <users>
    <user id="cynthia"  email="cynthia@xxxxxxxxxxx"  global-notify="yes"/>
    <user id="bob"      email="bob@xxxxxxxxxxx"/>
    <user id="janet"    email="janet@xxxxxxxxxxxxxxx"/>
    <user id="jack"     email="jack@xxxxxxxxxxx"/>
  </users>

  <clients>
    <client id="frontside">
      <admin user="jack"/>
    </client>
    <client id="uptown">
      <admin user="cynthia"/>
    </client>
    <client id="duke"/>
  </clients>

  <monitors>
    <monitor client="frontside">
      <notify user="cynthia"/>
      <notify user="janet"/>
    </monitor>
    <monitor client="uptown">
      <notify user="janet"/>
    </monitor>
  </monitors>

</ming>


XSL:

<xsl:template match="monitor">

  <xsl:variable name="myClient" select="@client"/>

  <xsl:variable name="notifyList">
    <xsl:for-each select="notify/@user |
          /ming/users/user[@global-notify='yes']/@id |
          /ming/clients/client[@id=$myClient]/admin/@user"
    >
      <xsl:sort select="."/>
      <xsl:variable name="pos" select="position()"/>
      <xsl:choose>
        <xsl:when test="last() &gt; 1 and position()=last()"> and </xsl:when>
        <xsl:when test="position() &gt; 1">, </xsl:when>
      </xsl:choose>
      <xsl:value-of select="."/>
    </xsl:for-each>
  </xsl:variable>

  <p>
    Client: <xsl:value-of select="@client"/><br/>
    Notify: <xsl:value-of select="$notifyList"/>
  </p>

</xsl:template>



For client="frontside" this would output
"cynthia, cynthia, jack and janet"
(without sorting: "cynthia, jack, cynthia and janet").


thanks,
