docbook: Thread: Strange/buggy SGML export using LyX

Hi,

I'm still a little bit new to LDP,LyX and SGML but writing on the
Linux+IPv6-HOWTO I run inbetween now into three problems which I
believe that they aren't my fault.

Used LyX: 1.1.6fix1 on a Red Hat Linux 7.2 system
Template: docbook

$ more /usr/share/lyx/templates/docbook_template.lyx
#This file was created by <jamatos> Fri Sep 24 13:10:52 1999
#LyX 1.0 (C) 1995-1999 Matthias Ettrich and the LyX Team


----
1. problem:

A LyX table is not proper exported in SGML, the colspec tag is not
very well:

Example
  <colspec colname="col0" align="center"/>

and fix:
  - <colspec colname="col0" align="center"/>
  + <colspec colname="col0" align="center">


Ok, done by a selfmade Perl parser now after export


----
2. problem:

LyX sometimes exports left and right quotes which aren't understand
by "nsgmls"

Examples:
 &ldquo;
 &rdquo;

Fix: replace them with &quot;

Ok, done by a selfmade Perl parser now after export


----
3. problem

LyX doesn't "escape" "&" chars in exported URLs, but nsgmls don't
like this:

Example:

 <ulink
url="http://researchcenter.zdnet.com/data/detail?id=1001711171_237&ty
pe=RES&x=120054357">How Long the Aversion to IP Version 6</ulink> -
Review of META Group, Inc., full access needs (free) registration at
META Group, Inc.


Jade checker:

jade:../Linux+IPv6-HOWTO.sgml:4678:78:E: general entity "type" not
defined and no default entity
jade:../Linux+IPv6-HOWTO.sgml:4678:87:E: general entity "x" not
defined and no default entity

fix:

manual replace of "&" with "&amp;"
No idea for an automatic fix, because it's difficult to differ
between standalone "&" and "&" of starting entinites.


Are this problems known?

Are already fixes available (either LyX template or jade)?

TIA,
        Peter

LyX is exporting this and claiming that it's SGML?  That's not supported
by the standard SGML DCL.  XML uses that syntax by default.  Weird

Uh, those should work in DocBook, as far as I know.  I don't use them to
encapsulate text, instead I use <quote></quote>.  Don't know if LyX has
that capability.  This one warrants more investigation, to see why your
copy of Jade doesn't like those entities.

This is something horked in LyX.  Perhaps bug reports to the LyX folks
are in order.  I don't have a good work around though.

Lyx is up to lyx-1.1.6fix3-3. I had some installation issues on RH
7.1; see the Lyx list archive for the gory details.

I think the problems you desribe are Lyx issues; you might try the Lyx
list.
