Formatting an XML file via the "Output" function?

[Bombay]

I want to format an outputed XML file from a Form(i have created a button
that runs the output function.), when the file is outputed
it displays the table name. Id like to instead change the table name to a
different name.

Example of Data
<AUX_PO_NO>BARB0001</AUX_PO_NO>
<PO_HDR_DAT>2007-05-23T00:00:00</PO_HDR_DAT>
<PO_HDR_ORD_BY>BARBARA</PO_HDR_ORD_BY>
<PO_HDR_SHIP_VIA>TRUCK</PO_HDR_SHIP_VIA>
<PO_HDR_SPEC_TERMS>SPECIAL TERMS</PO_HDR_SPEC_TERMS>

Example of Formatted Data
<purchaseOrder>BARB0001</purchaseOrder>
<requestedDate>2007-05-23T00:00:00</requestedDate>
<orderedBy>BARBARA</orderedBy>
<shippingMethod>TRUCK</shippingMethod>
<billingTerms>SPECIAL TERMS</billingTerms>
