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. I am currently making the XSL result a SVGDocument like this:
DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
Document document = impl.createDocument(
SVGDOMImplementation.SVG_NAMESPACE_URI, "svg", null);
Element root = document.getDocumentElement();
javax.xml.transform.dom.DOMResult result = new DOMResult(root);
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";
xmlns:xlink="http://www.w3.org/1999/xlink";
contentScriptType="text/ecmascript"
zoomAndPan="magnify"
contentStyleType="text/css"
preserveAspectRatio="xMidYMid meet"
version="1.0">
<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>
</svg>SVGDOMImplementation.createDocument obviously creates the root node and the XSL translation results are put inside of it. Is there a better way to do this? TranscoderInput says that it takes a org.w3c.dom.Document but I get the following error when I try to pass in a Xerces DOM tree:
org.w3c.dom.DOMException: The current node (type: 9, name: #document) do not allow children of the given type (type: 1, name: svg:svg)
