Hello! Helder, thanks for your reply! Here is my full code:
// Get a DOMImplementation. DOMImplementation domImpl = GenericDOMImplementation.getDOMImplementation(); // Create an instance of org.w3c.dom.Document. String svgNS = "http://www.w3.org/2000/svg";; Document document = domImpl.createDocument(svgNS, "svg", null); // Create an instance of the SVG Generator. SVGGraphics2D svgGenerator = new SVGGraphics2D(document); // Draw svg svgGenerator.setPaint(Color.red); svgGenerator.fill(new Rectangle(10, 10, 100, 100)); // Try getting last element to set id Element root = document.getDocumentElement(); Node elem = svgGenerator.getRoot(root); while (elem.getLastChild() != null) { elem = elem.getLastChild(); } Element lastElement = (Element) elem; lastElement.setAttribute("id", "1"); // Do the same with the next rectangle svgGenerator.fill(new Rectangle(20, 20, 200, 200)); elem = svgGenerator.getRoot(root); while (elem.getLastChild() != null) { elem = elem.getLastChild(); } lastElement = (Element)elem; lastElement.setAttribute("id", "2"); // Finally, stream out SVG to the standard output using // UTF-8 encoding. boolean useCSS = true; // we want to use CSS style attributes Writer out = new FileWriter("test.svg"); // Next line prints garbage svgGenerator.stream(out, useCSS); // Get root of document for print out Node parent = lastElement; while(parent.getParentNode() != null) { parent = parent.getParentNode(); } TransformerFactory transfac = TransformerFactory.newInstance(); Transformer trans = transfac.newTransformer(); trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes"); trans.setOutputProperty(OutputKeys.INDENT, "yes"); //create string from xml tree StringWriter sw = new StringWriter(); StreamResult result = new StreamResult(sw); DOMSource source = new DOMSource(parent); trans.transform(source, result); String xmlString = sw.toString(); // print xml System.out.println("Here's the xml:\n\n" + xmlString); It's nearly the same as the one from the batik documentation[1]. I try to draw elements with SVGGraphics2D and right after each drawing operation, I add an id. With your last code snippet it "works", but propably not as intended, because commentaries of Batik are found once for each element. And second the streaming method of SVGGraphics2D is not working (before I used your snippet it didn't either) and I have to manually get the root of my dom tree and print it. Must I not change the dom tree while SVGGraphics2D is using it? Thanks in advance! Sebastian [1] http://xmlgraphics.apache.org/batik/using/svg-generator.html
