       ("incomingMessage",1,"resultMessage")

   </from>

   <to variable="tempVar"/>

</copy>

Example 2:

Removes the (N - 1) attachment; that is, removes the second-to-last attachment from the resultMessage variable, where N is the count of attachments on resultMessage.The return value of removeAttachment is copied to the unused tempVar.

<copy>

   <from>abx:removeAttachment("resultMessage",

     abx:getAttachmentCount("resultMessage") - 1 )

   </from>

   <to variable="tempVar"/></copy>

Example 3:

Copies the value of the Content-Transfer-Encoding property of the first attachment to the resultMessage variable.

<copy>
