Hi All -

I've got an XSL FO that looks good to me, but the FOP processor seems to
be ignoring empty blocks and blocks with whitespace.

The output I desire I am trying to achieve is:
--------
Line 1

Line 2
-------

None of these following XSL FOs produce the desired result.  Am I
missing something, or is this a limitation of FOP?

1.
<fo:flow flow-name="xsl-region-body">
<fo:block border-top-style="solid" padding-top=".15in"
space-after=".2in" font-family="arial" font-size="12pt">
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 1 </fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve"></fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 2 </fo:block> </fo:block> </fo:flow>

2.
<fo:flow flow-name="xsl-region-body">
<fo:block border-top-style="solid" padding-top=".15in"
space-after=".2in" font-family="arial" font-size="12pt">
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 1 </fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve"> </fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 2 </fo:block> </fo:block> </fo:flow>

3.
<fo:flow flow-name="xsl-region-body">
<fo:block border-top-style="solid" padding-top=".15in"
space-after=".2in" font-family="arial" font-size="12pt">
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 1 </fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve"> </fo:block>
  <fo:block white-space-collapse="false" whitespace-treatment="preserve"
linefeed-treatment="preserve">Line 2 </fo:block> </fo:block> </fo:flow>

Thanks,
Ted

The most important question is: which FOP version are you using?
I sincerely hope you're not stuck on 0.20.x, since it is notoriously  
non-compliant in terms of respecting preserved linefeeds and white-
space...

Option 1. will definitely not produce the intended effect, but both 2.  
and 3. definitely work in FOP 0.95.

As a small correction: the property "whitespace-treatment" does not  
exist. It should be specified as "white-space-treatment". FOP 0.95  
will exit with a ValidationException (unless you're using relaxed  
validation, which is not recommended)

If you are using 0.20.x and cannot upgrade, the effect of an empty  
line can normally be generated like so:

<fo:block
   space-after.optimum="1.2em"
   space-after.conditionality="retain"
   space-after.precedence="force" />



HTH!

Andreas

Hi Andreas -

FOP is bundled into another application I am using, and I'm not sure of
the version.  I'm looking into the FOP version.

This didn't work for me, unfortunately:
<fo:block
   space-after.optimum="1.2em"
   space-after.conditionality="retain"
   space-after.precedence="force" />

Should this work in all versions of FOP to create a blank line in an
RTF?

Thanks,
Ted

Errm... no sorry, I was unaware that you're using RTF output. In that  
case, you're already using one of the later versions, so it should  
work for PDF output at least.

For RTF output, I'm not 100% sure, but it may just work if you fill  
the block with a non-breaking space, as Oscar suggested earlier.


HTH!

Correct -

Methods 2 and 3 (from my original post, a block with space and a block with ) do create the intended output in PDF, but not when creating an RTF.

Unfortunately, if I use the non-breaking space ( ) in the FO, a visible character (Â) shows up in the RTF.  

Is the inability to create a blank line perhaps a known bug when using FOP to create RTF?  I've seen other posts from users that are creating RTF that don't mention this issue...

Thanks,
Ted
