The code in the following example copies a BPEL 1.1 expression evaluating from the string literal 'GE' to the symbol field within the indicated variable part. (Note the use of the double and single quotes.)

<assign>
   <!-- copy from string expression to the variable -->
   <copy>
      <from expression="'GE'"/>
      <to variable="output" part="payload" query="/p:result/p:symbol"/>
   </copy>
</assign>

The following example shows how to perform this expression in BPEL 2.0.

<assign>
   <copy>
      <from>'GE'</from>
      <to>$output.payload/p:symbol</from>
   </copy>
</assign>
