Re: Dynamic Table Generation

Hi all

Thanks to the help I received earlier in the week on this list, I am making good progress. 

You'll remember that I was trying to generate a table of services (y-axis) and the content-types (x-axis) which listed the content types used by a particular service (much like a spreadsheet). While the stylesheet can build the table/column headings ok, 
the problem I have is when it comes to put crosses in the boxes marking the appropriate content types used. The template below performs the correctly when a service variant has zero or one content-types, note the correction to the XSL code enabling me to 
step through $content-types. 

The problem is when a service-variant uses multiple content-types. The template below adds another set of n 'td' elements for each content-type used by the service (where n is the size of the $cotent-types). The behaviour required is
- for exactly n td elements to be included in each row
- for a 'x' to put in the appropriate table-cell(s) indicating which content type(s) are used

What I think I need to do is:
- build each table row (of blank table cells) before entering into the foreach $content-types loop
- inside the foreach $content-types loop
  - perform the current test comparing $a to the ith content-type in $content-types
  - if the condition holds, add a 'x' to that 'td' element.

Trouble is I don't know how:
- to sample what the text value of the current element in XSL 
- to add text data to an element

Any ideas/comments will be welcome.

Thanks

Nigel
