Oracle Webcentet Content | Can we use conditional idoc script statement for file store provider's we

Hi,

My requirement is to have different web url for PDF and non PDF content.

For example : When there is PDF content then path will be

$FsHttpWebRoot$groups/$dSecurityGroup$/$dDocAccount$/documents/$dDocType$/$dDocName$$RenditionSpecifier$$RevisionLabel$$ExtensionSeparator$$dWebExtension$

When there a non PDF content then path should be

$FsHttpWebRoot$groups/$dSecurityGroup$/$dDocAccount$/documents/$dDocType$/$Year$/$Month$/$Day$/$dDocName$$RenditionSpecifier$$RevisionLabel$$ExtensionSeparator$$dWebExtension$

I would like to put if else condition and join above two statements like

$FsHttpWebRoot$groups/$dSecurityGroup$/$dDocAccount$/documents/$dDocType$$if $dWebExtension$ = pdf$/$else$/$Year$/$Month$/$Day$/$endif$$dDocName$$RenditionSpecifier$$RevisionLabel$$ExtensionSeparator$$dWebExtension$

But this is not working.I am not able to find any thing which will provide information to use conditional statement in weburl.file
