Mapping 3 columns to 3 attributes in the same element

Question

Hi,
I have 3 columns which are not in a collection as part of my result set. I need to map these 3 columns to an attribute in my result xsd in the transformer.
eg on the left I have :
addrline0, addrline1, addrline2. On the right I have an element called ADDR with an index attribute, so I want the right to display
<ADDRESS>
<ADDR index="0">my address1</ADDR>
<ADDR index="1">my address 2</ADDR>
<ADDR index="2">my address 3</ADDR>
</ADDRESS>
this seems not possible in the transformer out of the box - is there a way I can achieve this ? I know that addrline0 will always map to index 0 and addrline1 always map to index 1 etc.
thanks

The way to do it would be:
Assign the first one normally:
<assign name="first">
<copy>
<from variable="addrlin0" query="pVariable"/>
<to variable="ADDR" query="/tns:ADDRESS"/>
</copy>
</assign>
then assign the following using :
<bpelx:assign>
<bpelx:append>
<from variable="addrlin1" part="return" query="/pVariable"/>
<to variable="ADDRESS" query="/tns:ADDRESS"/>
</bpelx:append>
</bpelx:assign>
Instead of append you can also use InsertAfter or InsertBefore.
