Hi David, One thing I still need to investigate was Jeroen's reply:
Hi Robby, have you checked this page [1]? I'm not sure if this is the same component, but is might lead you further. [1] http://wiki.apache.org/cocoon/ValidationTransformer Jeroen I checked that (probably somewhat deprecated) documentation but i noticed something that could be usefull: <map:transform type='validate' src='validation/xhtml1-transitional.dtd'> <map:parameter name='active' value='true'/> <!-- this part --> </map:transform> If i find some time this week I will check if setting that 'active' parameter to true does any good unless you beat me to it ;-) Robby -----Oorspronkelijk bericht----- Van: David Crossley [mailto:cross...@apache.org] Verzonden: do 30-6-2011 8:46 Aan: dev@cocoon.apache.org Onderwerp: Re: Does ValidatingTransformer support DTD validation David Crossley wrote: > Robby Pelssers wrote: > > > > i am trying to use the validating transformer with a DTD but can't get it > > to work. > > IIRC when i set this up for Apache Forrest a while back, > then i could not get DTD validation working either. > So we converted the DTD to RELAX NG using Trang. > > Some of the notes and links here might help: > http://forrest.apache.org/howto-dev.html#debug-validation > https://issues.apache.org/jira/browse/FOR-1172 > > (I have been trying to investigate this for ages. > Sorry, not much time, so i hope this much helps.) > > No matter what i do to configure the transformer, there are only > three default grammar for SchemaParser instantiated > (DEBUG messages in core.log).
