Hi, Just a note: Rahul says return "null" from method resolveEntity to ignore a DTD: I presume he meant to say "return an empty stream" or "return a stream containing an empty DTD".
Returning null will cause xerces' default behaviour to occur, which *will* load the DTD from the remote location. Jeff is quite correct to point out that if the DTD referenced contains entity references, default values for attributes, etc., then ignoring it will affect the content of the original XML document. If this is the case, then you should instead keep a local copy of the DTD, and use the EntityResolver to return the contents of that file. Note that disabling *validation* merely suppresses error messages. The DTD or schema files still need to be loaded because they can set default attributes, and other things that are nothing to do with validation. So turning off validation won't get Xerces to stop loading external DTDs or schemas; extra steps are needed. You do mention that you tried setting this feature to false: http://apache.org/xml/features/nonvalidating/load-external-dtd"; I would have thought that would have done the trick without having to define an EntityResolver... It might be worth trying to set this feature to false before going to the effort of writing an EntityResolver. From the description it looks like it might be what you want: http://apache.org/xml/features/external-parameter-entities http://xml.org/sax/features/external-parameter-entitieshttp://xml.org/sax/features/external-parameter-entities Regards, Simon On Wed, 2003-04-16 at 04:35, Jeff Greif wrote: > Alternatively, you can provide an EntityResolver that will resolve the > SystemId (the URI) of the DTD to a copy on the local filesystem of the > parsing application. > > In general, even a non-validating XML parser is supposed to read the > DTD to supply default values for attributes and to expand entity > references.
