How to display just the variable != NULL


Hello everybody,
 
I want to know the way of using condition in visualforce page. I have a custom object 'Stagiaire__c' having few fields:Name,CNE,e-mail,date_de_naissance,Téléphone
 
I want to create a PDF documents whish display just the fields are not NULL
if for exemple,"CNE == null" , <p> CNE: </p> will not display in my PDF
 
Here is my code:
<apex:page standardController="Stagiaire__c" renderas="pdf" showheader="false" applyhtmltag="false" >
    <apex:pageBlock title="Fiche Stagiaire">
           <apex:pageblockTable value="{!Stagiaire__c}" var="s">
              <p>Nom & Prénom: </p>   <apex:column value="{!s.Name}"/>
              <p>CNE:</p>                  <apex:column value="{!s.CNE__c}"/>
              <p>Téléphone! </p>          <apex:column value="{!s.Téléphone__c}"/>
              <p>E-mail: </p>               <apex:column value="{!s.e-mail__c}"/>
     </apex:pageblockTable>
   </apex:pageblock>
  </apex:page>

should I create an apex Class ? if yes , how I will relate it to my page Visualforce?

You can use following code
  
<apex:page standardController="Stagiaire__c" renderas="pdf" showheader="false" applyhtmltag="false" >
    <apex:pageBlock title="Fiche Stagiaire">
           <apex:pageblockTable value="{!Stagiaire__c}" var="s">
              <apex:outputpanel rendered="{!if(s.Name!=null,true,false)}">
               <p>Nom & Prénom: </p>   <apex:column value="{!s.Name}"/>
              </apex:outputpanel>

<apex:outputpanel rendered="{!if(s.CNE__c!=null,true,false)}">   <p>CNE: </p> <apex:column value="{!s.CNE__c}"/> </apex:outputpanel>

<apex:outputpanel rendered="{!if(s.Téléphone__c!=null,true,false)}">   <p>Téléphone!  </p> <apex:column value="{!s.Téléphone__c}"/> </apex:outputpanel>

<apex:outputpanel rendered="{!if(s.e-mail__c!=null,true,false)}">   <p>E-mail:</p> <apex:column value="{!s.e-mail__c}"/> </apex:outputpanel>

    </apex:pageblockTable>
