Hello,
I want to add a <use> element to my svg document by creating and
adding it to the DOM with Java. Here's the code:
DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
SVGDocument doc = svgCanvas.getSVGDocument();
Element qm = doc.createElementNS(svgNS, "use");
qm.setAttributeNS(null, "xlink:href", "#QuestionMark");
qm.setAttributeNS(null, "overflow", "visible");
qm.setAttributeNS(null, "width", "10.512");
qm.setAttributeNS(null, "height", "26.273");
qm.setAttributeNS(null, "x", "-5.256");
qm.setAttributeNS(null, "y", "-13.137");
qm.setAttributeNS(null, "transform", "matrix(1 0 0 -1 27.7561
292.2344)");
doc.getElementById("animatedBackground").insertBefore(qm, null);
System.out.println(DOMUtilities.getXML(qm));
At the line with the insertBefore() call I get the following error:
org.apache.batik.bridge.BridgeException:
file:/C:/Users/Julian/workspace/Multiquiz/src/gui/svg/mq-login.svg:0
The attribute "xlink:href" of the element <use> is required

This is quite strange because it says the xlink:href attribute is
missing, which is not true.
I'm using the current version of Batik available in the SVN branch
with Sun Java 6 on Windows Vista, coding with Eclipse Ganymede.
I hope somebody can help me.
Regards,
Julian
