Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jakarta-commons Wiki" for change notification.
The following page has been changed by SimonKitching: http://wiki.apache.org/jakarta-commons/Digester/FAQ The comment on the change is: Add info on setting up schema validation for the input document ------------------------------------------------------------------------------ More information on !EntityResolver behaviour can be found here: http://xml.apache.org/commons/components/resolver/resolver-article.html + + == How can I validate the input document against a schema? == + + Unfortunately, validation of xml documents against schemas is not currently standardised, + ie the procedure for configuring this is parser-specific. + + Some digester maintainers feel that Digester should provide the ability to turn on document + validation, and therefore the following methods have been defined on the Digester class: + {{{ + Digester.setValidating + Digester.setSchema + Digester.setSchemaLanguage + }}} + If you get validation working using these, then please document the procedure here. In particular, + you may wish to look at the source for the !ParserFeatureSetterFactory and the classes in the + org.apache.commons.digester.parser package. + + However other digester maintainers feel that as this functionality is complex to set up and + not currently portable the best approach is for users to configure the parser first, then + pass the parser to the Digester object. This makes it possible for users to write test code + to get the document reading and validating working first without involving digester. This + approach will result in something like the following: + + {{{ + SAXParserFactory f = SAXParserFactory.newInstance(); + f.setValidating(true); + SAXParser p = f.newSAXParser(); + p.setErrorHandler(new MyErrorHandler()); + // do parser-specific stuff to set up schema validation here + + // here you can test whether you have got the schema validation correctly set up by + // just trying to parse the document. once that is working correctly, add the code + // below to hook a digester instance up to that parser... + + Digester d = new Digester(p); + p.setContentHandler(d); + p.setDTDHandler(d); // optional + p.setEntityResolver(d); // optional + + // add digester rules here + d.parse(...); + }}} + --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
