Hi folks,
I've been playing with this idea for quite a while now, here's
a quick proposal for an XML configuration file (/etc/ax25/ax25config.xml).
What do you think?
<?xml version="1.0" standalone="no" encoding="iso-8859-15">
<!DOCTYPE ax25config SYSTEM "file:///usr/share/ax25/ax25config-0.0.dtd">
<ax25config>
<!-- Please note that many parameters will be optional -- the ones
that are not is up to discussion. This is just an outline for
the general idea.
This file is supposed to be read by:
- a startup-script at system boot, I guess perl or python
is needed, I haven't seen an XML parser for bash yet.
- ax25-lib
- authoring tools
It substitutes /etc/ax25/{ax,nr,rs}ports and hopefully makes it
easier to maintain the parameter settings and routing tables for
the various protocols. Extensions can be easily added to the
(to be written) DTD. The XML parser should barf, but not bail-out,
when it encounters unknown tags. It should (at least) complain
loudly about otherwise malformed data.
I haven't thought too long about the "attributes" vs. "elements"
question.
