Hi All,

I have a requirement to generate an XMl file using ESQL. The source for this interface is database

The structure of the XML is such that, it has one tag called party, which should appear twice with same root tag but with different sources.

<Envelope>
<Party partyType="PSI" partyRole="sender">
</party>
<Party partyType="TDP" partyRole="receiver">
</party>
</Envelope>

and my ESQL code is
SET OutputRoot.XMLNSC.INSTAT.Envelope.Party.(XMLNSC.Attribute)partyType ='PSI';

SET OutputRoot.XMLNSC.INSTAT.Envelope.Party.(XMLNSC.Attribute)partyRole =Ref.Agent1;

SET OutputRoot.XMLNSC.INSTAT.Envelope.Party.(XMLNSC.Attribute)partyType ='TDP';
SET OutputRoot.XMLNSC.INSTAT.Envelope.Party.(XMLNSC.Attribute)partyRole =Ref.Agent2;

When I execute this code, the 'Party' tag is generated only once and it always picks up the second value, First value is getting replaced.

Is it possible to generate the XML with the above structure, If so, how can it be achieved?

Yes! ( I don't think message broker would be the market leading ESB if it could not write a simple XML document ).

Declare two reference variables. One to point at InputRoot.Ref, the other pointing at OutputRoot.Envelope.
Then use the CREATE statement to add new elements under the OutputRoot reference.

See http://publib.boulder.ibm.com/infocenter/wmbhelp/v8r0m0/topic/com.ibm.etools.mft.doc/ak04950_.htm
and
http://publib.boulder.ibm.com/infocenter/wmbhelp/v8r0m0/topic/com.ibm.etools.mft.doc/ak04864_.htm

There are simpler methods that involve using a loop and array indexes, but REFERENCE variables always perform better.
