The way you describe the problem:
"...storing that information, then
using that to reference values when iterating through rows?..."
suggests you are still thinking in terms of procedural programming, where
you tell the machine what order to do things in, and save data "early on"
for use "later".
The key to this kind of problem is to structure your code according to the
output you want to produce. Something like this:
<thead><tr>
<xsl:for-each select="timePoint[1]/Value/@Label">
<td>Dose</td>
<td><xsl:value-of select="."/></td>
</xsl:for-each>
</tr></thead>
<tbody>
<xsl:for-each select="timePoint">
<tr>
<td><xsl:value-of select="../@Dose"/></td>
<xsl:for-each select="Value">
<td><xsl:value-of select="."/></td>
</xsl:for-each>
</tr>
</xsl:for-each>
</tbody>
This is assuming the structure of your input is as regular as your sample
seems to suggest.

Subject: [xsl] Finding unique columns for building a table ...
Hi all - I've just started using XSLT, so apologies if this is a basic
question.
I would RTFM but my colleague has TFM so I can't at the moment!
Anyway, the question:-
I have an XML document that looks like this ...
<?xml version="1.0" encoding="UTF-8"?>
<myRoot>
<myResults>
<myOutput Dose="1">
<timePoint time="1">
<Value name="P50" Label="Median">1924.836</Value>
<Value name="P2.5" Label="2.5%">1194.928</Value>
<Value name="P97.5" Label="97.5%">2598.446</Value>
</timePoint>
<timePoint time="2">
<Value name="P50" Label="Median">1851.636</Value>
<Value name="P2.5" Label="2.5%">1723.220</Value>
<Value name="P97.5" Label="97.5%">2024.470</Value>
</timePoint>
...
What I want to do is build a table using 2/3 predefined
columns and all
columns I have "value" for at each timePoint (eg. P2.5, P50
and P97.5 in
this case). So, I want my output to look like this:-
Dose Time Median 2.5% 97.5%
1 1 1924.836 1194.928 2598.446
1 2 1851.636 1723.220 2024.470
.
I can see how I could iterate through and build the "rows" of
the table
output, but I can't see how I figure out how many columns of
values there
are in the first place. Does anyone have a good approach to
finding all
columns (P50, P2.5 and P97.5 in this case), storing that
information, then
using that to reference values when iterating through rows?
Many thanks for any help .
Rich.
