The ora:getAttachmentContent function reads SOAP attachment content and encodes that data in Base64 format in a BPEL process by providing the BPEL variable as an argument, which has an href of the SOAP attachment. The following example shows how to use this function:

<copy>
   <from expression="ora:getAttachmentContent('input','bin')"/>
   <to variable="initiateTaskInput" part="payload"
    query="/taskservice:initiateTask/task:task/task:attachment/task:content"/>
</copy>

The preceding example copies the attachment content, which has its href stored in the "input/bin" variable, to the content variable in Base64-encoded format.
