Yes there is. You can use the (de facto standard) parseXML function.
This is usually used from script, and unfortunately I can't see a way to
access the Window object to get at the parseXML method without
evaluating some script. So you could perhaps do the following. I
extend the JSVGCanvas here to get access to the script interpreter:
<untested-code>
import org.apache.batik.script.Interpreter;
// ...
public class MyJSVGCanvas extends JSVGCanvas {
/**
* Returns an Interpreter for the currently loaded document.
*/
public Interpreter getInterpreter(String type) {
return bridgeContext.getInterpreter(type);
}
}
// ...
String xml = "<polygon fill=\"none\" points=\"240.0, 243.0, ...\"
stroke=\"#000000\"/>";
Interpreter in = mycanvas.getInterpreter("text/ecmascript");
Node n = (Node) in.evaluate("parseXML('" + xml + "')");
SVGDocument doc = mycanvas.getSVGDocument();
doc.getDocumentElement().appendChild(n);
</untested-code>
