Thank you very much, i think it will help; now i should retrieve the base64
string to feed ParsedURL. To retrive the base64 string, i do the following:
......
if (id != null && id.getNodeValue().contains("Picture")) {
Node grandchild = child.getLastChild();
NodeList grandchildren = grandchild.getChildNodes();
if (grandchildren.getLength() == 1) { // base 64 image
SVGOMImageElement ie = (SVGOMImageElement)
grandchildren.item(0).getLastChild();
......
but after that, i cant get the string with the line "String image =
ie.getHref().getAnimVal();"
would you give any suggestion?
Best Regards.
