Re: Xalan transform hand-built DOM

Hi,

I'm using Xalan version 1.9 and Xerces version 2.6 in C++
on windows. I'm having a problem using XalanTransformer.

I am building up a DOM by hand.
I have defined my own classes that derive from XalanNode
and XalanDocument and so on.
I've tried this approach to using XPathEvaluator.evaluate
and it worked fine.

Now I am trying the same thing with XalanTransformer.transform
I assumed that because there is a constructor for
XSLTInputSource that takes a XalanNode* then I could use that.
In effect I have code like this

        XalanNode *node;
// Stuff to set up the input DOM in node
        XSLTInputSource input(node);
        transformer.transform(input, stylesheet, output);

(Where I've glossed over the setting up the XSLTInputSource
for the stylesheet the XSLTResultTarget for the output and the
XalanTransformer itself.)

When I try this I get an error:

SAXParseException: An exception occurred! Type:RuntimeException, 
Message:The
primary document entity could not be opened. Id={null} (, line 0, column 0)

The fact that this is a SAX parse exception makes me think
that the transformer is going off and try to parse my DOM object!
Also when I try to follow the flow through the debugger it
seems to be going off to do a parse.
This all suggests that I am doing something rather fundamentally wrong.

What approach should I be taking to transform a DOM I've built by hand?


Well, it's a code path that certainly hasn't been well-tested for quite 
a while.  Can you create Jira issue, and attach the source code for a 
trivial program that reproduces the problem?

Thanks,

Dave
