Re: expand conditional variable in xsl:key match

I see.  Looks like my options are:
1. investigate forward-walk
2. enhance incoming data (the current design is to
keep process prior to XSLT generic with no business
logic, this will have to break that)
3. go back to Saxon6.0.2.  Somehow variable was
allowed in xsl:key match/use in that version, I had to
expand the variable out when I upgraded to Saxon6.5.2,
which is the cause of this problem I am having now. 
When the variables are expanded out, the performance
went down drastically concurrently, which is another
reason I might decide to go back.
4. wait until WebLogic6.1 supports JDK1.4 and move up
to Saxon7.5.1 (this probably will never happen)

Since we might want to skip WebLogic7.1, we seems
committed to WebLogic6.1 for an extended period,
therefore option #3 might be the most viable at this
time for me.

Any suggestion would be very much appreciated.

Thanks,
Xiaocun

Xiaocun,

I suggest you think about how to split your process
in two, one to enhance 
the data, one to do the grouping.

If this is not possible, your problem just looks
tough. The key-based 
grouping technique can only be pushed so far.
Another technique to think 
about is a forward-walk (a recursive template that
chooses the nodes to 
group one node at a time, but stops on certain
conditions). I suppose if 
you're desperate for something to do Friday night,
you might want to try 
this just for fun. (Sorry I can't promise to be
around to help.)

I hope that helps, anyhow,
Wendell

Hi,

  I am using Saxon6.5.2.  I have a variable
InstructionHeaderRow declared to mark the end of

the

document as below:
<xsl:variable name="InstructionHeaderRow">
  <xsl:choose>
    <xsl:when test="$InstructionHeader/@row &gt;

0">

      <xsl:value-of

select="$InstructionHeader/@row"/>

    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="//row[last()]/@row +

1"/>

    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>

I need to create a xsl:key to apply to all rows
between $QuestionHeaderRow and

$InstructionHeaderRow:

<xsl:key name="QuestionKey" match="//row[(_at_)row &gt;
$QuestionHeaderRow and
        @row &lt; $InstructionHeaderRow]"
use="string(cell[(_at_)column=$QuestionnaireColumn])"/>

Since XSLT1.0 does not allow variables in xsl:key
match and use, how best to exand the conditional
variable $InstructionHeaderRow so I can use it in
xsl:key match above?

Any suggestion would be very much appreciated.
