Select divs between html comments in lxml

Question

This is my html file

<div>
   <div></div>
   <div></div>
   <!--Comment1-->
   <div>1</div>
   <div>2</div>
   <div>3</div>
   <!--Comment2-->
   <div></div>
   <div></div>
   <div></div>
</div>

and I want to select divs between Comment 1 and Comment 2

With this xPath = "/div/comment()" I can select <!--Comment1--><!--Comment2-->

But I want to select this

   <div>1</div>
   <div>2</div>
   <div>3</div>

Answer 1

//*[preceding-sibling::comment() and following-sibling::comment()]

Or stricter version:

//*[preceding-sibling::comment()[. = 'Comment1'] 
    and following-sibling::comment()[. = 'Comment2']]
