XML : Oracle APEX 4.2 Charts Custom XML IF ELSE IF Not Working

I defined cdata format of oracle apex bar chart tooltip value based on IF ELSE IF but no text shown in tooltip ,but tooltip apears without text i.e blank XML Code I am specifying is :

     <tooltip_settings enabled="true">                 <IF>          <Condition %SeriesName="Last_YR_CUR_MON_TD?">               <format><![CDATA[{%Name}{enabled:False} - {%Value}{numDecimals:0,decimalSeparator:.,thousandsSeparator:\,} (&P4_LAST_YR_CUR_MON_ALIAS.)]]></format>          </Condition>      </IF>      <ELSE>                <format><![CDATA[{%Name}{enabled:False} - {%Value}{numDecimals:0,decimalSeparator:.,thousandsSeparator:\,} (&P4_CUR_YR_CUR_MON_ALIAS.)]]></format>        </ELSE>   </tooltip_settings>    

Is there syntax problem of IF ELSE IF? What is the syntax of IF ELSE IF Condition in XML?
