prod2 | 11.00 11.00 10.00
prod3 | 12.00

The XML for this table is:

<price_summ>
<prod name="prod1">
<loc name="loc1">
<price>10.00</price>
</loc>
<loc name="loc3">
<price>12.00</price>
</loc>
</prod>
<prod name="prod2">
<loc name="loc1">
<price>11.00</price>
</loc>
<loc name="loc2">
<price>11.00</price>
</loc>
<loc name="loc4">
<price>10.00</price>
</loc>
</prod>
<prod name="prod3">
<loc name="loc2">
<price>12.00</price>
</loc>
</prod>
</price_summ>

I can apply a template on <prod> and would like to do so on <loc>, but how do I fill-in the location cells that do not have a value.

I've used the algorithm listed below, but THERE HAS TO BE A BETTER WAY!

(BTW, the alorithm below is an example of my procedural thinking.)

Any ideas?

template select="prod"

<tr>
<td>value-of select="prod/@name"</td>

choose
when select="loc[@name="loc1"]
<td>value-of "loc[@name="loc1]/price</td>
/when
other
<td> </td>
/other
/choose
choose
when select="loc[@name="loc2"]
<td>value-of "loc[@name="loc2]/price</td>
/when
other
<td> </td>
/other
/choose
choose
when select="loc[@name="loc3"]
<td>value-of "loc[@name="loc3]/price</td>
/when
other
<td> </td>
/other
/choose
choose
when select="loc[@name="loc4"]
<td>value-of "loc[@name="loc4]/price</td>
/when
other
<td> </td>
/other
/choose

</tr>
/template

del_me.txt
formated text of the message

I don't think that your problem can be solved by applying a template, as you want to force both a display order and a default value; you could play with xsl:key to simulate a grouping operation, but given that you are just handling 4 locations, your code could be the quickest way to achieve it.
