RE:  Grouping and Subtotals
David,

At 12:40 PM 4/1/2003, you wrote:
After the <xsl:for-each select> line, I created a $currentGroup
variable.  I then used it during the sum operation.  So far in my
testing, it appears to work.  Can anyone see anything wrong with this?

No, it is perfectly orthodox and designed to work like this.


You have bound your grouped nodes, together (i.e. as a set), to your variable, scoped within the for-each instruction. It being a node set, you can traverse from it, as you've discovered. Since your processor has the variable, it is spared having to call the key() function repeatedly (and the code is a little easier to read, too).

You don't need that extra self::node() step, however; for

$currentGroup/./ActualUnits

you will find that $currentGroup/ActualUnits will work just as well (and microseconds faster).

Cheers,
Wendell

        <xsl:variable name="currentGroup" select="key('listofbrochures',
BrochureName)" />

                                <xsl:value-of
select="format-number(sum($currentGroup/./ActualUnits),'#,##0')"/>
                        </td>
                        <td align="right" class="dataValue">
                                <xsl:value-of
select="format-number(sum($currentGroup/./RemainingProjected),'#,##0')"/
