RE: [docbook] Adding a new element to docbook

[JABakken at dstsystems dot com]

Thank you both very much for your replies. I usually have problems when I
try to use a public identifier (I get a "Connection refused" error
message), so I switched to using a system identifier. Is that okay if I do
that?

Here is now what mydocbk.dtd now looks like:

<!ENTITY % local.tech.char.class "|footer">
<!ENTITY % local.divcomponent.mix "|footer">
<!ENTITY % DocBookDTD SYSTEM "file:///C:/DocBook/DTD/docbookx.dtd">

%DocBookDTD;

<!ELEMENT footer (%para.char.mix;|%para.mix;)*>


Something is still amiss, though, because my output appears as follows:

This is only a sample.


<footer>This is the footer</footer>

My hunch is that it has to do with line 2 in my dtd. I wasn't quite sure
where I was supposed to put that line, so I just guessed.

One more thing: XML *requires* a system identifier.  So, this line needs to
be
<!ENTITY % DocBookDTD PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd";>

You can also use a local URI if you haven't configured a catalog yet.

(This is where the error message is coming from.  The parser just sees that
the character immediately following the public identifier is not
white-space, so spits out this message.  It would be nice if the message
were "missing system identifier" instead.)
