Using the FTC as an editor, then drawing rendered text

Hello. Perhaps this question has been asked before, please excuse the repetition.
I'm using FTC as an editor for a drawing program. In the window, I'm using a single canvas to render the drawn elements. Currently I draw shapes and text, but the text is only in a single font. I want to use the FTC editor in a separate window when the user double-clicks on the text object in the drawing. Then, let them edit the text, and then I'll render it again in the drawing.
It looks like the XML-based format is best for moving between instances of FTC in order to retain the most information about formatting and custom objects.
Then, how do I use the FTC engine to only render the formatted text in my custom canvas-based implementation. I just need to use the necessary facilities to accept the XML that was gathered from the FTC editor, and somehow "render" it in my own graphics context.
Perhaps a better way to phrase the question is, how do I go from XML from the FTC and then "render" the formatted text offscreen so that I can draw it to my custom canvas-based drawing environment? 

Please advise.

Thank you,

Ryan
