HELP : Embedding Large Number of Lines from an External File

[Danushka Menikkumbura-2]

Hi all,

My .fo file expects some content from an external XML file. This file contains large number of lines with indentation. When I get FOP to generate a PDF file out of this, I can observe that it just includes the bottom part of the XML file that can fit into a single page. FOP also igonores line indentation. Please advise how I could get FOP to have the content from the XML in multiple pages with indentation unchanged. Hope this could be solved by some XML-FO trick.

Which FOP version are you using? Can you perhaps send us the FO, so we  
can check on our end, and provide specific hints?

0.94

Well my .fo file is quite huge so that not possible to send it over :-(.

Thanks,

Any chance you can try 0.95 and check if the issue persists?

Try to trim it down, then. Ideal would be the smallest possible FO  
that triggers the behavior.

Hi Andreas,
 

Any chance you can try 0.95 and check if the issue persists?

I switched to 0.94 due to some table formatting issue in 0.95 so that it not an option.

Try to trim it down, then. Ideal would be the smallest possible FO that triggers the behavior.

Here we go ... also note that FOP does not preserve XML formatting when it adds my content into the PDF.

OK. I just tried your sample with latest FOP Trunk, and it reproduces  
the issue, but...

<snip />

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Here's what's bugging you. Specifying keep="always" on a block that  
does not fit into one page triggers this issue. (Note that keep-* are  
all inherited properties, so indirectly you're saying: keep this block  
and all of its descendants together within the same column)
Why precisely FOP decides to only retain the last part, is a question-
mark for me at the moment, but removing that property suffices to have  
the content distributed over multiple pages.

Besides that:

> space-before.maximum="6pt" space-after.minimum="0pt" space-

I added the property "white-space-treatment='preserve'" to retain the  
indentation. If you don't specify it, the indenting spaces will be  
suppressed because they a follow a preserved linefeed.

HTH!
