standardization-efforts concerning output of validating parsers

Question posted by: jean-gert nesselbosch (Guest) on October 20th, 2005 03:05 PM

hello everybody,

does anybody know of standardization efforts concerning the output
of w3cSchema/relaxNG-validating parsers ?

I use libxml2 for validation-purposes (w3c-Schema and relaxNG) and have
the impression that

(a) the output in case the xml-document is not valid, is not very verbose
(b) the structure of the returned message (in case of the xml-document
not beeing valid) is...well, it's just text. would be nice, if
theparser
would return some standardized xml
(c) there's no possibilty, neither in w3c-Schema nor in relaxNG (Schematron
is another case, but unfortunately I can't make use of it in
theenvironment
I'm programming for) to add "error_message-tags" to the schema file at
the appropriate places (at least not those that would be recognized by
the parser in case of a validation-error) containing self-explanatory
error- messages, hints how to make the parsed xml-document valid
or whatever.

right now, it seems to be (almost) impossible to automatically read the
output of a validating parser, extract the important information and
present it to the user.

gruss,
jean-gert
