Hi, How about trying this ways 1) String s = <g id="101" ....> </g> surround it with svg tag eg: <svg xmlns="..">your <g> element </svg>
2) parse it using batik svg parser not the default Java DocumentBuilder parser, Batik svg parser is namespace aware. 3) append as usual, but keep in mind that the <g> element is one layer deeper than previous because of the surrounding <svg> tag Regards Tonny Kohar On Tue, 2007-04-24 at 04:50 -0400, [EMAIL PROTECTED] wrote: > 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"?
