Hello, I try to add new SVG content to a SVG Document which already exists.
1) I load a svg file with the jsvgcanvas class svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC); svgCanvas.getActionMap().get(JSVGCanvas.RESET_TRANSFORM_ACTION).actionPerformed(ae); svgCanvas.setURI(url); 2) I get the SVGDocument object which contains DOM tree of the SVG document = svgCanvas.getSVGDocument(); 3) I get a String (=new svg content) from a Servlet String s = "<g id="101" name="test" xmlns="http://www.w3.org/2000/svg";> <polyline points="8325 2232, 8325 2540" style="fill:none; stroke:rgb(255,000,000);"/> <polyline points="7925 2232, 7925 2540" style="fill:none; stroke:rgb(255,000,000);"/> <polyline points="7525 2232, 7525 2540" style="fill:none; stroke:rgb(255,000,000);"/> ... </g>" 4) I parse it into a new Document object InputSource is = new InputSource(new StringReader(s)); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document newLayer = db.parse(is); 5) I add the root element of the new document in the main document Element root = (Element)document.getDocumentElement(); Node a1 = document.getElementById("1"); Element newLayerRoot = (Element)newLayer.getDocumentElement(); //add the new Layer to the main document a1.appendChild(document.importNode(b1, true)); svgCanvas.setSVGDocument((SVGDocument)document); ------------------------------------------------------------------------------------------- The problem is that the JSVGCanvas doesn't refresh! However: -When I serialize the main document after the add of the new content, The final document is ok! If I open load it with the svgcanvas.seturi(), It show me the good picture with the new content. BUT: There is smth special with the namespace of the g element from the newLayer document. There is no namespace for this element in the file <g name="it is the good string" id="101"> -svgCanvas is svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC); -if I try to add a simple rect, it works!: String svgNS=" http://www.w3.org/2000/svg";; Element groupe = document.createElementNS(svgNS, "g"); Element rectangle = document.createElementNS (svgNS, "rect"); rectangle.setAttributeNS(null, "x", "1200"); rectangle.setAttributeNS(null, "y", "2200" ); rectangle.setAttributeNS(null, "width", "3100"); rectangle.setAttributeNS(null, "height", "3510"); rectangle.setAttributeNS(null, "style", "stroke: red; fill: red;"); groupe.appendChild(rectangle); a1.appendChild(rectangle); But: I must add the new element from a String! so I can't create new ElementNS. I try to add the namespace to the String "<g id="101" name="test" xmlns="http://www.w3.org/2000/svg";>..." But smth is strange with the namespace: Element b1 = (Element)newLayer.getDocumentElement(); //b1 is the g element from the string System.out.println("Element:" + b1.getTagName() + " Name:" + b1.getAttribute("name") + " Namespace:" + b1.getNamespaceURI()); //gives me: "Element:g Name:test Namespace:null" --------------------------------------------------------------------------------------------- Why getNamespaceURI() gives me "null"? Why when I serialize the document it doesen't show me any namespace for this element? How can refresh a JSVGCanvas when I add a new String with a namespace (which disapear during the parsing...) to a SVGDocument which already exists? Help!
