The following provides an example of bpelx:insertBefore syntax in a BPEL project that supports BPEL version 2.0. In BPEL 2.0, the functionality is the same as described in bpelx:insertBefore in BPEL 1.1, but the syntax is slightly different. An extensionAssignOperation element wraps the bpelx:insertBefore extension.

<assign>
   <extensionAssignOperation>
      <bpelx:insertBefore>
         <bpelx:from>
            <bpelx:literal>
               <a:city>Redwood Shore></a:city>
            </bpelx:literal>
         </bpelx:from>
         <bpelx:to>$addrVar/a:state</bpelx:to>
         </bpelx:insertBefore>
   </extensionAssignOperation>
</assign>
