The contents of the html page can be transferred into a question text field or a boilerplate.
If you use groups in Limesurvey you can then put a hidden question (text oder equation) in the group which copies the result of the composing via javascript into the hidden answer field.
Haven't the code on you example. So I am not sure what will be the text result of the composing. But once you got the question recreated inside LimeSurvey I sure a few people in the forum can provide a helping hand with the result transfer.
