[xml/sgml] How to reference docbookx.dtd via file://?

[Jeff Chimene]

Hi,

I'd like to prevent docbookx.dtd from being referenced
via http:// It looks like I can reference docbookx via
file://. However, here is a <trimmed> log from a
recent run where XML_DEBUG_CATALOG=1 showing that the
catalog resolution occurs via the network, not
locally.

As you can see, the "system match" happens via http://
instead of file://

Thank-you in advance for your support!

I sent the following message to the XSLT list. It was
probably the wrong list.
