The following example shows an example that uses the function getCurrentDate in BPEL 1.1.

<!-- execute the XPath extension function getCurrentDate() -->
<assign>
   <copy>
      <from expression="xpath20:getCurrentDate()"/>
      <to variable="output" part="payload"
         query="ns1:invoice/invoiceDate"/>
   </copy>
</assign>

The following example shows an example that uses the function getCurrentDate in BPEL 2.0.

<assign>
   <copy>
      <from>xpath20:getCurrentDate()</from>
      <to>$output.payload/invoiceDate</to>
   </copy>
</assign>

In the following example, the formatDate function converts the date-time value provided in XSD format to the string 'Jun 10, 2005' (and assigns it to the string field formattedDate).

<!-- execute the XPath extension function formatDate() -->
<assign>
   <copy>
      <from expression="ora:formatDate('2005-06-10T15:56:00',
         'MMM dd, yyyy')"/>
      <to variable="output" part="payload"
         query="ns1:invoice/formattedDate"/>
   </copy>
</assign>

The following example shows how the formatDate function works in BPEL 2.0.

<assign>
   <copy>
      <from>ora:formatDate('2005-06-10T15:56:00','MMM dd, yyyy')</from>
      <to>$output.payload/formattedDate</to>
   </copy>
</assign>
