RE: [xsl] Create Table

2010-03-22 04:39:05

There's a shortcut for this kind of expression that's worth knowing:

if (data[(_at_)section='changes' and @field=$x]) then
                 data[(_at_)section='changes' and @field=$x] else ' '">

can be rewritten as

(data[(_at_)section='changes' and @field=$x], ' ')[1]

That's assuming that the expression data[(_at_)section='changes' and @field=$x]
selects 0-or-1 elements.

The table body can also be generated using an XPath 
expression which avoids the spurious non-breaking space and 
lets you specify attribute field's values in a sequence:

<tbody>
   <!-- ... -->
   <xsl:for-each 
select="BOM/interface-categories/category[(_at_)category='Source']">
      <tr>
        <xsl:for-each select="for $x in 
('file','version','date','user',
                                         'cr_number','comment') return
             if (data[(_at_)section='changes' and @field=$x]) then
                 data[(_at_)section='changes' and @field=$x] else 
'&#160;'">
           <td><xsl:value-of select="."/></td>
        </xsl:for-each>
      </tr>
    </xsl:for-each>
</tbody>

There are a series of data nodes that represent either headings or

different value of the element, or I could even create a whole new 
table.


I've given a solution which includes <tbody> elements, you can 
extrapolate that into different tables if needed.


The problem I am having is testing if a fild is missing, 
some entries 
don't have a field="file for example.  In that case I have 
to leave a 
blank cell.


Using a recursive push solution is best for building the 
structure of 
the tables, while filling the cells in your case calls for a pull 
solution.  I mocked up a source file that isn't an exact 
fit, but does 
illustrate your issue, that's listed first, followed by the XSLT.

My thinking, obviously, is that an extra nbsp doesn't hurt anything.

HTH,
