Hi,
Thank you for your reply.
I am having difficulty "creating a Jira" issue.
I assume that to do this I need to be able to access
"http://nagoya.apache.org/jira";
and I have not been able to do this all day.
Jira is really very unstable, so I'm not surprised.
I have, as suggested, created a trivial program that illustrates the
problem.
It is based on the XalanTransfrom example with minimal changes.
It is attached.
Hopefully it shows where I am going wrong.
Maybe the problem is with my approach rather than any bug in Xalan.
OK, the bad news is this is really something we haven't supported in a
very long time. In fact, I'm not sure if XalanTransformer ever
supported using a pre-built tree in this way. We should probably remove
the XalanNode constructor from XSLTInputSource.
The good news is the way you can do this is fairly straightforward. You
need to create your own derivative of XalanParsedSource, and wrap your
document instance in that. You really need to do a bit more work to get
your own XalanDocument implementation to work anyway.
To get your own custom implementation of XalanDOM to work you need to
provide a derivative of the DOMSupport class that understands your
implementation. You can probably just use DOMSupportDefault, but you
should create your own if you can optimize node-ordering for your
implementation. For example, XalanSourceTree (the default
implementation) uses indexing to support fast node ordering. I would
highly recommend you do something like that, if you want to see
reasonable performance.
Once you've done that, you can create a XalanParsedSource derivative
that wraps your XalanDocument instance. That's trivial, and you can
look at the existing code in the XalanTransformer directory for ideas.
Of course, you can always use XercesDOMWrapperParsedSource with an
instance of the Xerces-C DOM that you've built by hand, and forget about
creating your own XalanDOM. In addition, if you can build your DOM
instance in document order, you can use Xalan's default XalanDOM
implementation, and just build it using hand-made SAX events. Take a
look at the DocumentBuilder sample for more information.
Feel free to post again if this isn't clear, or you have more questions.
