Hi Lars,
That entity is actually used by the automatic
indexing templates. I had originally placed it in docbook.xsl because I
had custom indexing templates in there, but I moved those templates to
xhtml-element-mods.xsl (which also has that entity, BTW). It is no longer
needed in docbook.xsl, and will be removed from the next beta. I'm glad it
worked, but I'm mystified why it did not work before.

Hi Bob,
If I remove
<!DOCTYPE xsl:stylesheet [
<!ENTITY % common.entities SYSTEM "../common/entities.ent">
%common.entities;
]>
from the xhtml5/docbook.xsl the conversion works fine without
xerces-j.
I have no idea what the above entry is used for ;-) so I have no idea if
that is a solution or creating a problem elsewhere.

Hi Bob,
The xhmlt5 Stylesheets work fine under Windows7 (without the xerces-j
parser for me).

Hi Bob,
I was testing under Linux with Ubuntu 10.04, just in case you have
easy access to a Linux box this might help you to reproduce the
error.
I will also re-build the example on Windows7 and let you know if it
works or not.

Hi Lars,
This is strange. While I always use
the Xerces-J parser with Saxon 6, I did not mean to introduce a new
dependency on it. I just ran it again with Xerces turned off and
its jar file excluded from the classpath, and the xhtml5/docbook.xsl and
chunk.xsl work fine without it. I'm running java version
"1.6.0_05" on Windows XP under Cygwin. So I'm not able to
reproduce your error yet. My command looks like this:
java -cp saxon.jar com.icl.saxon.StyleSheet
-o mybook.html mybook.xml
../docbook-xsl-1.76.1/xhtml5/docbook.xsl
You say the html and xhtml stylesheets work
without xerces-j, but I don't think the xhtml5 stylesheets are doing
anything fundamentally different from those stylesheets.
They all pull in stylesheet files from other directories using relative
paths. For example, the html/autoidx.xsl file has the same
relative path entity declaration:
<!ENTITY % common.entities SYSTEM
"../common/entities.ent">
%common.entities;
Also, the html/docbook.xsl file imports
templates using relative pathnames:
<xsl:include
href=""/>
I wonder why it works in those instances
but not in the xhtml5 instance? I wonder if that error message is being
helpful in identifying the source of the problem.

Hi Bob,
thanks for the reply. I believe I found
the issue. I wasn't using xerces-j but the standard Java libraries.
I tried with html, xhtml and xhtml1-1 and they seem to be
working fine without xerces-j . With xerces-j the convertion works
fine with and without Ant.
Is the usage of xerces-j intended?
I'm not familiar with the differences of xerces-j and the standard
Java ones but it seems that the existing libraries work fine without
xerces-j.

Hi Lars,
I have not tried it with Saxon 9, but
since saxon 9 lacks the exsl:node-set() function, then the
stylesheet will need to be changed to work with Saxon 9.
The error with Saxon 6 is odd,
because that is what I used when testing it. The error
message:
java.net.MalformedURLException: no protocol:
../common/entities.ent
seems to be saying that relative URLs
starting with "../" are malformed because they lack a protocol part,
but that is always true for relative URLs. And the other
stylesheets use that syntax in several modules. I don't
understand why you are getting that error. Can you run Saxon
outside of Ant and reproduce the same error?
That entity declaration for
../common/entities.ent at the top of the docbook.xsl file is no
longer needed. I moved the templates that used those entities
(indexing templates) to the html5-element-mods.xsl file, so the
entity declaration is needed there. If you remove it from the
docbook.xsl file, does it still fail when it is encountered in
html5-element-mods.xsl?

Hi Bob,
these are great news, thank you. I tried using
the xhtml5 stylesheets.
Unfortunately I receive an error
message. I tried with Saxon9 and Saxon6.5.5
Here is the
error message for Saxon9:
[xslt]
/home/vogella/workspace/docu/de.vogella.docbook/docbook-xsl-1.76.1/xhtml5/html5-element-mods.xsl:456:
Fatal Error! Cannot find a matching 1-argument function named {http://exslt.org/common}node-set(). There is no
Saxon extension function with the local name
node-set
Here is the error message for
Saxon6.5.5
[xslt] Loading stylesheet
/home/vogella/workspace/docu/de.vogella.docbook/docbook-xsl-1.76.1/xhtml5/docbook.xsl

FAILED
/home/vogella/workspace/docu/de.vogella.docs/buildhtml5.xml:535:
javax.xml.transform.TransformerConfigurationException:
java.net.MalformedURLException: no protocol:
../common/entities.ent
Here is the Apache Ant file which
I'm using for the transformation:
<target name="build-html5" depends="xinclude"
description="Generates HTML5 files from DocBook
XML">
<xslt
style="${myhtml.stylesheet}" extension=".html"
basedir="${output.tmp}"
destdir="${article.dir}">
<include
name="**/*article.xml" />
<param
name="html.stylesheet" _expression_="${stylesheet}"
/>
<param name="section.autolabel" _expression_="1"
/>
<param name="make.valid.html" _expression_="1"
/>
<param name="html.cleanup" _expression_="1"
/>
<param name="chunker.output.encoding" _expression_="UTF-8"
/>
<outputproperty name="indent" value="yes"
/>
<classpath refid="saxon.class.path" />
</xslt>
<!-- Copy the stylesheet to the top level
directory-->
<copy
todir="${article.dir}/..">
<fileset
dir="lib">
<include
name="styles.css" />
</fileset>
</copy>
</target>
The same conversion works fine using the
existing html or xhtml stylesheets.

Lars

I've got the DocBook XSL stylesheet for
generating HTML5 output and EPUB3 books working, at least to
beta level. If you are interested in trying it out, you
can download the files from the DocBook SourceForge Files area,
under the EPUB3 folder
https://sourceforge.net/projects/docbook/files/epub3/
It
currently consists of two directories that are added to an
existing docbook-xsl-1.76.1 installation, adding "xhtml5" and
"epub3" directories. They are actually customizations of
the xhtml stylesheets, and contain relative path references to
those files, so they should be installed in parallel with the
xhtml directory. At some point I will incorporate them
into the normal build so they can appear in a regular
docbook-xsl-snapshot.
Each directory includes a README
file to give you more information about how to use the
stylesheets and test your output. Feedback is
welcome.
The stylesheets include support for some of the
new EPUB features, such as video, audio, and MathML.
However, not all EPUB browsers are up to handling them.
See the README for details.
