Brian Minchau updated XALANJ-203:
---------------------------------
Version: 2.1.0
(was: Latest Development Code)
> Xalan forces validation when entities are declared
> --------------------------------------------------
>
> Key: XALANJ-203
> URL: http://issues.apache.org/jira/browse/XALANJ-203
> Project: XalanJ2
> Type: Bug
> Components: transformation, Xalan-interpretive
> Versions: 2.1.0
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Chris McCabe
> Assignee: Xalan Developers Mailing List
>
> When an internal DTD subset is declared in an XML file, Xalan forces
> validation
> of the XML file, even if the internal DTD is used only for declaring
> entities.
> In fact the DTD need not declare anything at all. The following simple XML
> will
> result in a parse exception being passed to the ErrorHandler that states
> 'Element "foo" must be declared', even when validation is explicitly disabled
> before the transformation:
> <!DOCTYPE foo []>
> <foo/>
> This is only apparent when an ErrorHandler is set on the XMLReader. Without
> the
> ErrorHandler, you will never see the exception and the transformation will
> succeed. A more realistic example:
> <!DOCTYPE foo [
> <!ENTITY more SYSTEM "test2.xml">
> ]>
> <foo>
> &more;
> </foo>
> The DTD is necessary for declaring the external entities, but you should still
> be able to turn off validation.
> The reason the validation is turned on after disabling it is because Xalan
> sets
> the dynamic validation feature of Xerces, which turns on validation when it
> sees
> the DTD. Disabling dynamic validation does not seem to have any negative
> impact
> on the Xalan transformation.
