Defining and reusing an EL variable in JSF page

Is it possible to define variable and reuse the variable later in EL expressions ?

For example :

<h:inputText 
   value="#{myBean.data.something.very.long}"
   rendered="#{myBean.data.something.very.long.showing}"
/>

What i have in mind is something like :

<!-- 
     somehow define a variable here like : 
     myVar = #{myBean.data.something.very.long} 
-->
<h:inputText 
   value="#{myVar}"
   rendered="#{myVar.showing}"
/>

Any ideas ? Thank you !
