I tried the above method but my code is in a module and it doesn't work. but anyway I found the solution.
It's my fault since I didn't read all the documentation, sorry.
there is a specific insert tag for my problem: {{iflng::*}} {{iflng}}
I'm using it and it works perfectly:
Code:
{{iflng::it}}{{link_open::home-it}}{{iflng}}{{iflng::fr}}{{link_open::home-fr}}{{iflng}}
<li title="tab_Home" class="active">
{{iflng::it}}{{link_title::home-it}}{{iflng}}{{iflng::fr}}{{link_title::home-fr}}{{iflng}}</p>
{{link_close}}
