XML tags - how do I include them in the body of an email notification?

Hello!

I have a simple workflow that sends an email notification. I am trying to send the column values of the form with  XML tags in the body of the email, so that another application can pick it up and use the values transmitted. I enter the XML tags as texts, then insert the column/field names(see sample below):

<?xml version= '1.0' encoding= 'UTF-8'?>
<!DOCTYPE BioMed_Direct SYSTEM 'BioMed_Direct.v2.dtd' >
    <BioMed_Direct Cmd_Type='ADD' >
    <RequestReason>RequestReason</RequestReason>
    <BranchCCNo>BranchCCNo</BranchCCNo>
    <SubmittedBy>SubmittedBy</SubmittedBy>
    <WorkOrderNo>WorkOrderNo</WorkOrderNo>
</BioMed_Direct>

Unfortunately, when the email is sent, only the column/field values show in the body.
