Pat, thanks for responding
I inserted image doodad with xml like:
<image attachment="/pics/hills.jpg">
<caption/>
</image>
with code:
final CMutableDocument document = editor.getDocument();
final Point<ContentNode> point =
document.locate(Math.min(range.getAnchor(), range.getFocus()));
final HashMap<String, String> attributes = new
HashMap<String, String>();
attributes.put("attachment", "/pics/hills.jpg");
final ContentElement image = document.createElement(point,
"image", attributes);
final ContentElement caption =
document.createChildElement(image, "caption", new HashMap<String,
String>());
As I understand, others doodads work the same way.
Now I'm trying to figure out how to insert a text node. That code
makes no result:
caption.getContainerNodelet().getFirstChild().setNodeValue("image alt text");
