I am trying to figure out the easiest way to take the result of an XSL transformation, through Batik, then send the resulting PNG file to a web client.
[...]
Looking at the code the error below should only happen if you have two 'elements' at the top level of the source document. Alternatively if the Xerces document doesn't return the true root of the document from getDocumentElement().
So my guess is that the Xerces DOM is returning 'null' from getDocumentElement(), or your XSL transform is generating multiple 'top level' elements (which isn't allowed) I don't know if XSLT checks for this sort of error.

I am currently making the XSL result a SVGDocument like this:
The result of my translation looks like this:
<svg:svg xmlns:svg="http://www.w3.org/2000/svg"; width="185" height="100" viewBox="0 0 185 100"> <svg:title>Market Indices Chart</svg:title> ... </svg:svg>
The resulting SVGDocument looks like this:
<?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg"; <svg:svg xmlns:svg="http://www.w3.org/2000/svg";
