Ordering XML with conditions than generate new associ

Hi All, 

(I hope that you could forget and excuse my incorrect use of the language.)

 

This is a summarized example of my actual task. 

Ibm requesting help to the listbs members because I canbt find a correct solution.

 

--------------------------------------------------

My XSL is:

--------------------------------------------------

<?xml version="1.0"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 

<xsl:key name="order1" match="grade" use="((substring(var/pay,1,1))='') or ((substring(var/pay,1,1))='C')" />

<xsl:key name="order2" match="grade" use="concat(((substring(var/pay,1,1))='') or ((substring(var/pay,1,1))='C'),course[1]/teacher)" />

 

<xsl:template match='root'>

 

  <table>

  <!--Expecial logic for C pay nodes.-->

    <xsl:for-each select="grade[count(. | key('order1', 'true')[1]) = 1]">

      <xsl:if test="generate-id()=generate-id(key('order1', 'true'))">

      <tr><td><div><xsl:attribute name="id">credit_offer</xsl:attribute><table>

      <tr><td>Credit Offer</td></tr>

      <xsl:for-each select="key('order1', 'true')">

            <xsl:sort select="var/price" order="ascending" data-type="number"/>

                  <xsl:call-template name="course"/>

        </xsl:for-each>

      </table></div></td></tr>

        </xsl:if>

    </xsl:for-each>

    

  <!--Logic to group nodes with standar pays-->

    <xsl:for-each select="grade[count(. | key('order2', concat('false',course[1]/teacher))[1]) = 1]">

    <xsl:if test="generate-id()=generate-id(key('order2', concat('false',course[1]/teacher)))">

      <tr><td><div><xsl:attribute name="id"><xsl:value-of select="course[1]/teacher"/></xsl:attribute><table>

      <tr><td>Teacher's Leader: <xsl:value-of select="course[1]/teacher"/></td></tr>

      <xsl:for-each select="key('order2', concat('false',course[1]/teacher))">

        <xsl:sort select="var/price" order="ascending" data-type="number"/>

                  <xsl:call-template name="course"/>

        </xsl:for-each>

        </table></div></td></tr>

      </xsl:if>

    </xsl:for-each>

    

  </table>

  

</xsl:template>

 

<!--The rest.-->

<xsl:template name="course"> 

  <tr>

    <td><xsl:value-of select="position()"/>.</td>

    <td>Price: <xsl:value-of select="var/price"/>.</td>

    <td><xsl:apply-templates select='course'/></td>

  </tr>

</xsl:template>

 

<xsl:template match="course">

    <br/>teacher: <xsl:value-of select="teacher"/>&#xa0;&#xa0;

    class: <xsl:value-of select="class"/>&#xa0;&#xa0;

    shift: <xsl:value-of select="shift"/>&#xa0;&#xa0;

    Pay: <xsl:value-of select="../var/pay"/>

</xsl:template>

 

</xsl:stylesheet>

My problem lies on canbt establish a new group over node bcourse[1]/teacherb.

 

The Objectives are:

This is languagebs teacher board offer. I need sort teacherbs offers by price. And sort teachers from cheapest to most expensive. 

With this rule: bIf the course can pay with credit card or is not informed, itbs a promotion.b 

The promotions are a new group. And carry out the teacherbs rules.

Other additional complication: courses have two or more teachers. And the sorted group uses the first teacherbs name.

 

Thanks for your help, in advance.
