how to pass a normal DOM Document to JSVGCanvas with setSVGDocument?

[Jonas Ruesch <jo...@gmx.net>]

I use Xindice to store some SVG Documents and retrieve them
as a org.w3c.dom.Document, which I now would like to show with JSVGCanvas.setSVGDocument(svgdocu)

I tried:

i)
Document doc = ..//obtained from Xindice. Printed it out when getting it form the DB and is a correct SVG (generated with Sodipodi).
SVGDocument svgDoc;
SVGDOMImplementation impl = (SVGDOMImplementation) 
SVGDOMImplementation.getDOMImplementation();
svgDoc = (SVGDocument) org.apache.batik.dom.util.DOMUtilities.deepCloneDocument(doc, impl); 
// svgDoc.createElementNS("?","?"); // needs to be set correctly? 

This doesn't work. It seems to me after this operation all the attributes of the svg tags are removed??!!
JSVGCanvas says: " The attribute 'width' of the element <rect> is required"
and the this way cloned document looks printed like this:

<?xml version="1.0" encoding="UTF-8"?>
<svg contentScriptType="text/ecmascript" zoomAndPan="magnify" contentStyleType="text/css" id="svg548" sodipodi:docname="/home/yoyo/yoyo/eth/7_sem/semesterarbeit_xml_db/batik/rect.svg" xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd" version="1.0" width="210mm" preserveAspectRatio="xMidYMid meet" sodipodi:version="0.32" xmlns:xlink="http://www.w3.org/1999/xlink" height="297mm" xmlns="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" sodipodi:docbase="/home/yoyo/yoyo/eth/7_sem/semesterarbeit_xml_db/batik">
  <defs/>
  <sodipodi:namedview/>
  <rect/>  <---- wrong, was alright in the source Document
</svg>


ii)
DOMImplementation domImpl = SVGDOMImplementation.getDOMImplementation();
document = (SVGDocument)domImpl.createDocument(SVGDOMImplementation.SVG_NAMESPACE_URI, "svg",null);
		
			
DOMResult domResult = new DOMResult(document.getDocumentElement()); //give rootelement to domResult
DOMSource domSource = new DOMSource(node); // known node from the Document
//DOMSource domSource = new DOMSource(srcdoc.getElementsByTagName("svg").item(0));
		
// Use a Transformer for output
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
transformer.transform(domSource, domResult);

doesn't work either..?

iii)
Somebody wrote  the latest batik version JSVGCanvas contains a setDocument that accepts a normal DOM Document. I compiled 1.5 from 3.12.2003, didn't found the function?

After several hours of research....
I would be very,very glad if somebody may give me a hint or a little code-snippet that may help solving this basic problem.

Thanks a lot!

greetings

     Looking at the code in Batik, is it possible that the Attr nodes
returned from Xindice always returns 'false' from 'getSpecified()'?
This would cause exactly this sort of behaviour.

    Does this also produce a document w/o attributes?

    The actual definition is in batik.swing.svg.JSVGComponent.

    Of course the implementation of this uses the same DOMUtilities
method to make a Batik DOM from the generic DOM.

    Well you could copy the code from 
batik.dom.AbstractDocument.importNode and remove the check on
getSpecified() or fix Xindex's DOM (assuming I right above).
