Hi,
it seems nobody answers, so I will point you to my "dirty" code. I am a
student and not well experienced programmer, but maybe it is helpful
anyway.
I use this method:
private String generateSVG() throws
TransformerFactoryConfigurationError, TransformerException {
String result ="";
Transformer transformer;
transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// initialize StreamResult with File object to save to file
StreamResult streamResult = new StreamResult(new
StringWriter());
DOMSource source = new DOMSource(model.getSVGDoc());
transformer.transform(source, streamResult);
result = streamResult.getWriter().toString();
return result;
}
I use the String, which is returned with another method, to write it to
the disk:
private void saveFile(File saveFile, String xmlData) throws IOException
{
// File saveFile = new File(filename);
if(!saveFile.exists()){
// System.out.printf("Create new File %s. \n", filename);
saveFile.createNewFile();
FileWriter fw = new FileWriter(saveFile);
fw.write(xmlData);
fw.close();
} else {
System.out.printf("ERROR: File %s already exist. Did
nothing. \n",
saveFile.toURI().toString());
}
}
I attached you the complete file. Hope this help you.
Regards,
Keywan
