Your test.svg file does not have the proper DOCTYPE to say that this is an SVG document. So you should add the following lines in test.svg <?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd";> <svg xmlns="http://www.w3.org/2000/svg"; xmlns:xlink="http://www.w3.org/1999/xlink"; width="???" height="???"> ... </svg> > 2) why isn't the transcoder throwing an exception on the SVG Document? See thomas's analysis. Conlcusion: SVG relies on DOM level 2 spec which is namespace aware. So you always have to use the createElementNS(svgNs, localName) method. Where svgNS is the namespace URI of SVG, and localName is the local name of the element to create. PS: to set attributes, use setAttributeNS(null, qualifiedName). For futher details regarding why 'null' is used (attributes are always in the default namespace) - see the W3C namespace specification.
