xsl:fo - keeps and breaks problem..

2002-09-12 01:08:52
Hi All
 
I'm using XSL/FOP to generate PDF files from an XML source document... 
 
Roughly speaking, the XML contains a long list of nodes of the same
element name with different attributes and child nodes..
 
e.g. simplified..
 
<foo type="a" name="Fooey"/>
<foo type="b" name="Dooey"/>
etc.
 
some nodes have nested foo's inside them...
 
<foo type="a" name="Fooey">
      <foo type="x" name="FooChild"/>
      <foo type="y" name="FooChild2"/>
</foo>
 
So far I've written a single template match for the foo element that
returns a fo:block (of full page width) for each match and calls itself
if it has any foo children, thereby producing nested fo:blocks where
appropriate..
 
The problem that I'm having is when trying to prevent any one foo result
from splitting over two pages. I'd like to keep all the contents of one
foo match together (ignore the nested ones for now); so either encourage
it to keep on one page or break and go to the next. 
 
I've played around with adding the break-after/break-before attributes
on the fo:block inside the template, but because it is being called
recursively this results in one page for each result (I can probably fit
about 6 matches on one page before it needs to break)
 
Any ideas about how to control this ?  Maybe I'm missing a simple
attribute somewhere...
 
 
Cheers

 
Andy
