Fop Warnings
Just yesterday I got fop 0.95 installed to try tp make a pdf version
of the GnuCash (www.gnucash.org) guide, and the resukts look great for
the first time. Obviously some tinkering will need to be done, but
that is to be expected for a newbie to docbook and fop.
I got a slew of warnings, most self-explanatory.
My question is:
Is there a way to get fop to point to the source of the warnings?
I've tried the -d (debug) option and that didn't help.
Thanks.
-Tom

You're right, of course. As a matter of fact, I use xsltproc.

Hi,
Just a little precision, for the sake of correctness.

Strictly speaking it’s not FOP that produces the XSL-FO, it’s the XSLT
processor configured in your Java installation, that is called by FOP.
You can configure another XSLT processor, or even use a non-Java one
(e.g., xsltproc) in a prior step. For the rest you’re definitely right.

FWIW: You could also eliminate the need to use another tool to do the
indenting, and obtain a similar effect by adding
<xsl:output ... indent="yes" />
to the main stylesheet. With Saxon you'll get indented XML as a
result by default (3 spaces added for each level). The number of
spaces can be controlled via the saxon:indent-spaces extension
attribute (on xsl:output)
Xalan offers xalan:indent-amount for control the amount of spaces to
add for each level, which defaults to zero, so only adds linefeeds
unless the extension attribute indicates otherwise.

Thanks for the additional info, John, good idea.

One more thing: the XSL-FO produced by FOP does not contain any
new line characters, so FOP will tell you that the error is on line 1 at
position 7458 o something similar. You can format the XSL-FO using
'xmllint --format' before running FOP. xmllint is part of the libxml2
project.

You have to write the XSL-FO produced by the XSLT processor into a file.
FOP will then be able to point you at the line and column numbers where
the errors or warnings come from. Since you’re asking this question
I guess that right now you’re producing the PDF like this:
fop -xml document.xsl -xsl stylesheet.xsl -pdf document.pdf
For debugging purpose you can proceed in two steps:
fop -xml document.xsl -xsl sytesheet.xsl -foout document.fo
(Or directly call your favourite XSLT processor to produce the FO file.)
fop -fo document.fo -pdf document.pdf
Note that that won’t point you to the DocBook source, unfortunately.

source that corresponds to. Tedious, but I’m not sure there is any
immediate solution to that.
