it was forrest that woke me up to relaxng, but i'm up to a number of things atm - this wasn't top of the list...
i'm completely lost where cocoon ends and forrest starts, i'd like to see validation first and worry about project boundaries second imho as for cocoon components (brainstorm):- - does validation ocur at the parser level or the sitemap level or both? a quick win could be:- - use the XNIConfigurableFileGenerator from forrest - add Andy Clark's JingConfiguration and Jing ( http://www.apache.org/~andyc/neko/doc/index.html ) - configure in sitemap:- <map:match pattern="[pattern]"> <map:generate src="[filename]" type="xni"> <map:parameter name="config-class" value="org.cyberneko.relaxng.JingConfiguration" /> <map:parameter name="grammar" value="[grammar-filename]" /> </map:generate> .... </map:match> would require some hacking, but i think this generator needs a clean-up anyway but then again, this would only work at start of pipeline... a win all round could be:- "validator" components, with variants of "doctype|schema|relaxng" (would xpath be handy as well?) - definitions passed in through sitemap could override those in files (spec says these are only hints) - errors cause redirection to error page or logging or whatever is configured - i could see XNI being the saviour here, we could provide doctype/schema from xerces and relax from neko + jing, also allows anyone else to define their own validation components if they need them - issues are reliance on xerces and pre-sitemap validation (perhaps multiple parser configs in cocoon.xconf? but how does code choose which to use?) - don't know enough technicalities about mid-pipeline components what do you think? ian David Crossley wrote: >Ian Atkin wrote: > > >>>David Crossley wrote: >>> >>>Please do not give up, Ian.
