As said at the very beginning of the topic, I didn't know where to go.
I am in front of a Himalayan climb with the wrong tools.
I did C coding years ago, not enough practice to save time.
Anyway, it was an enjoyable exercise, I appreciated your help and that of other readers.
I am more and more comfortable with Regex to correct and free up reading time, which is ultimately the ultimate goal.

Best regards

You can speed up some things. For example: create the questions giving to the div a unique id that you keep as list somewhere, and work only on correct answers. The wrong answers are linked to a non-existent id created with the original id with before a prefix. For example:

<div class="question" id="one">
<p>Who is the french king during the french revolution?</p>
<ul>
<li><a href="#due">correct answer</a></li> 
<li><a href="#wrong_uno">wrong answer</a></li> 
<li><a href="#wrong_uno">another answer</a></li> 
<li><a href="#wrong_uno">last answer</a></li> 

</ul>
</div>

<div class="question" id="two">
<p>Is Lady Oscar a real or fiction character?</p>
<ul>
<li><a href="#tre">correct answer</a></li> 
<li><a href="#wrong_due">wrong answer</a></li> 
<li><a href="#wrong_due">another answer</a></li> 
<li><a href="#wrong_due">last answer</a></li> 

</ul>
</div>

...and so on, working only on questions and correct answers. This is a more affordable work. After, you put the id list you kept on a blank text edit page:

one
two
three
four
...

And use a regex to create all the wrong answers for all the questions in an instant. Something similar to:

FIND:
(.+)

REPLACE:
<div class="answer" id="wrong_$1">
<p>Sorry, this was not the correct answer.</p>
<p><a href="#$1">Try it again</a><p>
</div>

In this way you can focus the work only on questions, and automate the creation of all the wrong answers pages. After the regex replace, you copy & paste the result in the same file of the questions.
Now you have a file with all the questions with correct and wrong links, as internal links. The last passage I suggest is to split this big file before every <div>, so you are sure to have a page break for each answer/question.
