I see you've made it easier for me by putting the "continued..." text in the page footer rather than in the table header. I misunderstood your requirement from your earlier post.


The table that normally stays at page ONE but could continue to page
TWO, should turn a toggle text in the footer of the first page: Let us
say: "Continued over the next page" or "First page only".

Yes, I understand that part.


I have reduced the challenge to the following stylesheet, beginning
with a short and a long text for easy testing:

And I've got a working example below.


            <fo:page-sequence master-reference="document">
                <fo:static-content flow-name="first_first">
                    <fo:block border-top="1pt solid black"
margin-bottom="0.5em"/>
                    <!-- Here we should have a toogle -->
                    <fo:block>Continued over the next page</fo:block>
                    <!-- if ITEMS continue to second page -->
                    <fo:block>First page only</fo:block>
                    <!-- if ITEMS stay on first page -->
                </fo:static-content>

And I tried to say before there is no such thing as a "toggle" in the static world of XSL-FO. The formatting object you cited is for interactive XSL-FO.


My solution below follows the pseudo-code I posted earlier in response to this thread, only retrieving page markers instead of table markers. The algorithm I gave you is sound, if I've understood your requirement. It is a very simple application of markers.

I hope this helps.
