I have an XML that generates a transaction file, it records entries from a Clubcard of how much was spent to earn points and the date it was done. There is no order that I can use as the same card number may appear further in the XML. What I would like is to get the XSL to find a card number (which I do not have a record of to use as an ID), put it in a <td></td> and show how much in total was spent, how much points were earned and what date it was done.

This is the XML…

<Root>

    <TicketEnd Date="2012-10-21" />
  </Events>
  <Ticket>
    <TicketStart Date="2012-10-22" />

  </Ticket>

    <TicketEnd Date="2012-10-22" />
  </Ticket>
</Root>

My XSL can only list the entries…

I have searched for examples but cannot find a scenario that has all these conditions and when put to a single XSL it fails.
Please help.

Here is the output file I would like to have…

<THEAD>
                <TR bgcolor="RGB(0, 204, 51)">
                    <TD width="25%"><font color="white"><B>Account Number</B></font></TD>

                    <TD width="25%"><font color="white"><B>Date</B></font></TD>
                    <TD width="25%"><font color="white"><B>Total Qualified Spent</B></font></TD>
                </TR>
            </THEAD>

If you want to total each card’s points and spend, then you will need to group the cards by their card number. In XSLT1.0, you use Munechian Grouping for this. This means defining a key for your group

<xsl:key name="cards" match="ClubcardPoints" use="@CardNo" />

Then, to select each distinct card number, you look for ClubcardPoints which occur first in the group for their card number. This is done as follows

<xsl:apply-templates 
   select="Root/Ticket/ClubcardPoints[generate-id() = generate-id(key('cards', @CardNo)[1])]" />

Getting the total points is then straight-forward

<xsl:value-of select="sum(key('cards', @CardNo)/@Points)" />

Here is the full XSLT (Note that I’ve simplified it to remove all the styling)

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="html"/>
   <xsl:key name="cards" match="ClubcardPoints" use="@CardNo"/>

   <xsl:template match="/">
      <table>
         <THEAD>
            <TR>
               <TD>Account Number</TD>
               <TD>Points</TD>
               <TD>Date</TD>
               <TD>Qualified Spent</TD>
            </TR>
         </THEAD>
         <TBODY>
            <xsl:apply-templates select="Root/Ticket/ClubcardPoints[generate-id() = generate-id(key('cards', @CardNo)[1])]"/>
         </TBODY>
      </table>
   </xsl:template>

   <xsl:template match="ClubcardPoints">
      <TR>
         <TD>
            <xsl:value-of select="@CardNo"/>
         </TD>
         <TD>
            <xsl:value-of select="sum(key('cards', @CardNo)/@Points)"/>
         </TD>
         <TD>
            <xsl:value-of select="@Date"/>
         </TD>
         <TD>
            <xsl:value-of select="format-number(sum(key('cards', @CardNo)/@QualSpend) div 100,'R#.##')"/>
         </TD>
      </TR>
   </xsl:template>
</xsl:stylesheet>

When applied to your sample XML, the following is output

<table>
   <THEAD>
      <TR>
         <TD>Account Number</TD>
         <TD>Points</TD>
         <TD>Date</TD>
         <TD>Qualified Spent</TD>
      </TR>
   </THEAD>
   <TBODY>
      <TR>
         <TD>1042540000026</TD>
         <TD>12</TD>
         <TD>2012-10-22</TD>
         <TD>R600.1</TD>
      </TR>
      <TR>
         <TD>1042540000019</TD>
         <TD>4</TD>
         <TD>2012-10-22</TD>
         <TD>R243.3</TD>
      </TR>
   </TBODY>
</table>

Note that, in XSLT2.0, grouping would be done by using the xsl:for-each-group element.
