DTD Validation Error

[rmohammed]

Hi Team,

I have downloaded the BITS-book-oasis2.dtd (ftp://ftp.ncbi.nih.gov/pub/jats/extensions/bits/2.0/) and validated same DTD in Oxygen but it throw the below error against the soextblx.dtd in local path: C:\Program Files (x86)\Oxygen XML Editor 16\frameworks\docbook\4.5\dtd\soextblx.dtd

Description: Element type "thead" must not be declared more than once.
Description: Element type "tbody" must not be declared more than once.
Description: A '(' character or an element type is required in the declaration of element type "entry".

Please help to resolve this issue. So that we can validate any XML files.

Regards,
Raja

Hi Raja,

Oxygen uses the standard XML catalog support to resolve various DTD references. And a DTD which describes the CALS table model is also present in the Docbook framework configuration.
If you go to the Oxygen Preferences->"Document Type Associations" page you can uncheck the Docbook 4 and Docbook 5 framework configurations and then save the preferences. Then try again to open and validate your DTD.

Radu
