Re: [xsl] Create Table

[bernie bonn <moochambo@xxxxxxxxx>]

HI Eric,  as always thanks for your help!

I am getting so close.  What you
gave me didn't completely solve the problem, but it helped me to think what
the context is, and I did some more research to get the table looking like I
wanted.  (Not sure if it is the best way to do it, but I can worry about that
later).  

So I have my table built with all the source changes, now I want to
add a row with the 'diffs' for each change(could be 30 or more nodes).  The
challenge is after i have grabbed  the the File, version, date etc for the
first row,  I need to then somehow grab all the data nodes where @field=diff,
until the next node where @field!=diff, and place it in the next row.  Off
topic, I plan on using JavaScript to hide the diff detail unless use wants to
see it.  Seems like a while loop, but I know those don't exist.  I also am
currently experimenting with named templates, although struggling with how to
set context.  

Sorry this is so muddled, let me know if you need
clarifications.  
Thanks again,

Bernie

Heh, don't listen to me,
I'm still learning myself... number() isn't 
needed here, as this works just
fine:

<th><xsl:value-of select='./@lineId+1'/></th>

What I've just learned,
is that I need to take a closer look at how
XSLT processors handle typing, my
answer assumed number() was needed in
order to perform addition like you were
trying, and was thus totally 
wrong.

Anyway, I played around with it a bit
more, adding this to my <tr>
template:

<xsl:param name='x'
select='./@lineId'/>

And changing the <th> two different ways, as follows:
<th><xsl:value-of select='following-sibling::data[@lineId=$x]/@lineId'/></th>
<th><xsl:value-of
select='following-sibling::data[@lineId=$x+1]/@lineId'/></th>

The first line
results in <th/>, the second line works as expected.
The first line can be
rewritten as select='//data[@lineId=$x]/@lineId' 
and it will work as
expected.  So I suspect your problem is one of not
minding your context node,
i.e. you started with this:

<xsl:param name='x' select='./@lineId'/>

Then,
you have <xsl:value-of select='data[@lineId=$x]'/>, which can't 
work  because
you haven't selected an axis...  So it's hard to know how 
to specifically
help you here -- the 'data[@lineId=$x]' is correct, but 
only if it's preceded
by a proper axis, and followed by '/@lineId' since 
you're after attribute
content, instead of element content.
