Re: [xsl] Re: XSL-FO: Creating Marginalias with Apache FOP

I corrected my xml:
(the number and order of maintextX and marginaliaX varies):

It was still not well formed. And I disambiguated the data values to illustrate the correct values were being used in the result.

My PDF output should look like this:

-----------------------------------------------
| <marginalia1> | (Nested table:) <title>     |
|               |-----------------------------|
|               | (Nested table:) <maintext1> |
|               |-----------------------------|
|               | (Nested table:) <maintext2> |
|---------------------------------------------|
| <marginalia2> | (Nested table:) <maintext2> |
|               |-----------------------------|
|               | (Nested table:) <maintext3> |
|---------------------------------------------|
| <marginalia3> | (Nested table:) <maintext4> |
-----------------------------------------------

Forgive me but I don't know what you want where you say "nested table:".

Yes, all of the elements have unique names.

I'm assuming they have to have something in common, say the prefix "marginalia", otherwise there is no determinant trigger.

As I said earlier, you need to use group-starting-with="" in order to infer structure from a flat set of constructs.

I hope the example below (in HTML) helps. I'll leave the XSL-FO as an exercise. The crux of your issue is how the XSLT works. When you look at the resulting HTML below you'll see your table as you've indicated above.
