[exhibit] How 'remove' function works

[mikima]

hi to all
i'm using exhibit for an univeristy project.
i want that if a property has a value, exhibit print a sting, but if the property has no value; exhibit show nothing.
To be more clear i post the code i've wrote:


<div class="title"
       ex:content="if(exists(.platform), 'This item is part of:', '')"></div>

        <div class="text"
               ex:content=".platform"></div>


In this way, if .platform has no value, exhibit put an empty line, and i don't want this.

i hope to have explained my problem (i'm not so good with english).
What can i do? there is a solution? i've seen that there is a function 'remove', but i didn't understand how it works.

thanks
michele

Here is in easier way:

<div ex:if-exists=".platform">This item is part of: <span
ex:content=".platform"></span></div>
