Hi,

i know there are old topics with the same problem, but nothing there helped me. I am trying to access element in xml message, which has namespaces.


Input message:

<?xml version="1.0" encoding="UTF-8"?>

</GeneralTDS:GeneralTDS>

)
)
)



How did i try:

DECLARE NS1 NAMESPACE 'http://www.ibm.com/websphere/crossworlds/2002/BOSchema/GeneralTDS';
--DECLARE NS1 NAMESPACE 'GeneralTDS';
SET OutputRoot.XMLNS.envelope.attachment = InputRoot.XMLNS.NS1:GeneralTDS.Data;
SET OutputRoot.XMLNS.envelope.attachment0 = InputRoot.XMLNS.NS1:GeneralTDS.NS1:Data;
SET OutputRoot.XMLNS.envelope.attachment1 = InputRoot.XMLNS.GeneralTDS.NS1:Data;
SET OutputRoot.XMLNS.envelope.attachment2 = InputRoot.XMLNS.GeneralTDS.Data;
SET OutputRoot.XMLNS.envelope.attachment3 = InputRoot.XMLNS;
SET OutputRoot.XMLNS.envelope.attachment4 = InputRoot.XMLNS.(XML.Element)*.(XML.Element)NS1:Data;
SET OutputRoot.XMLNS.envelope.attachment5 = InputRoot.XMLNS.(XML.Element)NS1:GeneralTDS.(XML.Element)NS1:Data;



Result:

<envelope>
<attachment3>
<GeneralTDS:GeneralTDS xmlns:GeneralTDS="http://www.ibm.com/websphere/crossworlds/2002/BOSchema/GeneralTDS" xmlns:MO_GeneralTDSAttributes="http://www.ibm.com/websphere/crossworlds/2002/BOSchema/MO_GeneralTDSAttributes" verb="Create">
<GeneralTDS:Attributes>
<MO_GeneralTDSAttributes:MO_GeneralTDSAttributes version="3.0.0" verb="Create" locale="en_US" delta="false">
<MO_GeneralTDSAttributes:FileWriteMode>o</MO_GeneralTDSAttributes:FileWriteMode>
<MO_GeneralTDSAttributes:OutFileName>20070313143211593.dat</MO_GeneralTDSAttributes:OutFileName>
</MO_GeneralTDSAttributes:MO_GeneralTDSAttributes>
</GeneralTDS:Attributes>
<GeneralTDS:Data>dsfsdfsd</GeneralTDS:Data>
</GeneralTDS:GeneralTDS>
</attachment3>
</envelope>

What am i missing?

For me it should work with input message which you showed us here.

well it's not input message, i get this message generated in the middle of the flow. and it was generated like this:

DECLARE NS1 NAMESPACE 'http://www.ibm.com/websphere/crossworlds/2002/BOSchema/GeneralTDS';
DECLARE NS2 NAMESPACE 'http://www.ibm.com/websphere/crossworlds/2002/BOSchema/MO_GeneralTDSAttributes';
DECLARE ref_GeneralTDS REFERENCE TO "OutputRoot"."XMLNS"."GeneralTDS:GeneralTDS";
SET ref_GeneralTDS."GeneralTDS:Data" = CAST (InputRoot.BLOB.BLOB AS CHARACTER CCSID 819 ENCODING MQENC_NATIVE);


so as i understand, this isn't really an xml with correct namespaces, so this is how i access it:
InputRoot.XMLNS."GeneralTDS:GeneralTDS"."GeneralTDS:Data";
