My experiments lead me to believe that XMLmind is trying to load
external public identifiers before it tries to find an alternate using
its list of catalogs.
In particular, I have a document template which makes reference to a
public identifier on the Internet; that public identifier is noted and
redirected in a <public> element in a catalog loaded into XXE. This has
worked in all my tests until I tried this setup on an unnetworked
machine. After the initial install of the configuration when I try to
load or create a document of the particular type, I get the error:
Cannot open file "C:\Documents and
Settings\user\xxe2\config\ldocbook\ldocbook.xml":
docbook.sourceforge.net
When I provide a network connection for the machine, documents load
correctly. If I then remove the network connection, documents continue
to load correctly until I manually clear the XXE cache. I have attached
the catalog, template, and configuration file in case I've overlooked
something.
There is one possibility that I can think of in which it might be my
fault and not XXE's: it might be that correct processing of XML catalogs
requires the evaluation of all URLs, and that I should remap the URL
itself in the XML catalog; however, my study of the XML catalog
specifications has been inconclusive on this point. Any guidance would
be appreciative. It seems to me that simply specifying a <public>
element in the catalog ought to be adequate.
I should only need to use the <dtd> configuration element if I want to
enforce constraint on the documents that the documents don't specify
themselves, correct? (That is, the <dtd> element is not the appropriate
answer here, is it?)
Take care,
