    Dear all,

    I have used ECMAscript to add a SVG element to a webpage (I added a mouseover event to an existing svg element and the function it refers to creates a rectangle;
    Code:
    function bla (evt) {
          var svgNS = "http://www.w3.org/2000/svg";
          var vierkant = document.createElementNS(svgNS,"rect");
          rect1.setAttributeNS(null,"width",400); 
          rect1.setAttributeNS(null,"height",80);
          rect1.setAttributeNS(null,"x",100);
          rect1.setAttributeNS(null,"y",100);
          rect1.setAttributeNS(null,"rx",20); 
          rect1.setAttributeNS(null,"ry",20);
          rect1.setAttributeNS(null,"id","textblock");
          rect1.setAttributeNS(null,"visability","true");
          rect1.setAttributeNS(null,"stroke","black");              
          rect1.setAttributeNS(null,"fill","blue");
          rect1.setAttributeNS(null,"fill-opacity",0.2);
          document.getElementById("firstgroup").appendChild(rect1);
    }
    So far so good. But now I want to be able to click yet another element for this same rectangle to dissapear (be removed). Unfortunately, I did not find any possibilities to refer to this newly created rectangle. I added an id, but getElementByID does not seem to find it. I was hoping...

    var test = svgDocument.getElementById("textblock");
    test.parentNode.removeChild;

    ...would do the trick, but it doesn't.

    Any ideas?

    Robert
