docbook-apps

That is the problem, but I'm not clear why the DTD cannot be loaded. It certainly resides at that web address.

I would try setting up an XML catalog to redirect the URL to a local copy of the DTD. That would be faster than web access too.

Bob:

Thank you very kindly for the reply. I should have included the entire file in the example given,
it does indeed have a dtd, exactly as shown in your book:


"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd">
<chapter>
<chapterinfo>
<date id="DateVer">January 2012 Version 1.2.3</date>
<releaseinfo id="RelInfo">12-002009-16.c</releaseinfo>
<copyright id="Copyright">
<year>2012. All rights reserved</year>
</copyright>
</chapterinfo>...

However there is a peculiarity when running ANY file through xsltproc,
it complains about every file, included or omitted:

Version.xml:3: warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd">

which I honestly thought was just some noise as this usually does not interfere with the expected processing,
until now.
I suspect that would cause the issue. How can I get past that?

Migrating to docbook 5 is probably not an option at the moment.

Than you very much, not only for your reply, but for the great work you do supporting the community and in writing the Complete Guide!

In this section of my book:

http://www.sagehill.net/docbookxsl/ModularDoc.html#XincludeSelect

I address that problem with this sentence:

"For selections based on id, the included document must have a DOCTYPE
declaration
that correctly points to the DocBook DTD. It is the DTD that declares that id
attributes are of the ID type (the name id is not sufficient). If the file does
not
have the DOCTYPE or if the DTD cannot be opened, then such references will not
resolve."

So does Version.xml have a DOCTYPE declaration?

Looking at my own sentence, I have to think: what about DocBook 5 which does
not use
a DOCTYPE? No problem. DocBook 5 files use xml:id, which is predefined as of
type
ID.

Some background I am using xsltproc to process modular documents to pdf.
I have a file where I just want the one element included.
It is not getting included and I am getting error messages, like:
element include: XInclude error : could not load Version.xml

I would think it would be a xsltproc issue, but I am following the examples in
the
documentation and it is not working like that... so perhaps there is something
obvious
here I am overlooking.

so file Version.xml contains :

<chapter>
<chapterinfo>
<date id="DateVer">January 2012 Version 1.2.3</date>
<releaseinfo id="RelInfo">12-002009-16.c</releaseinfo>
<copyright id="Copyright">
<year>2012. All rights reserved</year>
</copyright>
</chapterinfo>...


In my file Book.xml
I am tring to include the date info...




<xi:include href="Version.xml" xpointer="xpointer(id('DateVer'))"
xmlns:xi="http://www.w3.org/2001/XInclude" />

I have also tried :

and



and none of these work, I am only interested in including the content of the
<date>
element from the Version.xml file.

Now were I to do, this,
<xi:include href="Version.xml" xpointer="element(/1)"
xmlns:xi="http://www.w3.org/2001/XInclude" />

then I get the entire contents from the Version.xml, which is not what I am
interested
in.
Is there something that I am missing here?
Why is this not working as indicated? Any suggestions?

Thanks,
/Gregorio
