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.
Best regards, Lars

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.

stylesheet available
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.
Best regards,
Lars

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
[xslt] Failed to process null

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.

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.
