Hi everybody!
My flow receives an XML message (SOAP) with namespaces. Here is the beginning of it:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2001/06/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:Header>
<app:ApplicationInf xmlns:app="urn:plant.ru:Envelope:ApplicationInf:1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<app:SoftKind>String</app:SoftKind>
<app:SoftVersion>String</app:SoftVersion>
<app:MessageKind>ABCD</app:MessageKind>
</app:ApplicationInf>
</env:Header>
I parse the message with XMLNS parser and I should check the value in
<app:MessageKind> field.
I wrote ESQL code:
CALL CopyEntireMessage();
DECLARE env NAMESPACE 'http://www.w3.org/2001/06/soap-envelope';
DECLARE app NAMESPACE '"urn:plant.ru:Envelope:ApplicationInf:1.0"';
IF InputRoot.XMLNS.env:Envelope.env:Header.app:ApplicationInf.app:MessageKind='ABCD'
THEN SET OutputLocalEnvironment.Destination.RouterList.DestinationData[1].labelname = 'ASG.001';
END IF;
But it doesn't work. Here is data from trace file:
"...
Executing statement ''IF InputRoot.XMLNS.env:Envelope.env:Header.app:ApplicationInf.app:MessageKind = 'RNTS.ASG.001' THEN... END IF;'' at ('.ASKTT_PreParse.Main', '8.3').
2007-03-03 17:05:51.162960 3828 UserTrace BIP2543I: Node 'ASKTT.Compute': ('.ASKTT_PreParse.Main', '8.6') : Failed to navigate to path element number '5' because it does not exist.
2007-03-03 17:05:51.163024 3828 UserTrace BIP2539I: Node 'ASKTT.Compute': Evaluating expression ''InputRoot.XMLNS.env:Envelope.env:Header.app:ApplicationInf.app:MessageKind'' at ('.ASKTT_PreParse.Main', '8.6'). This resolved to ''InputRoot.XMLNS.http://www.w3.org/2001/06/soap-envelope:Envelope.http://www.w3.org/2001/06/soap-envelope:Header."urn:plant.ru:Envelope:ApplicationInf:1.0":ApplicationInf."urn:plant.ru:Envelope:ApplicationInf:1.0":MessageKind''. The result was ''EMPTY ROW''.

This resolved to ''EMPTY ROW = 'RNTS.ASG.001'''. The result was ''NULL''.
2007-03-03 17:05:51.163097 3828 UserTrace BIP2537I: Node 'ASKTT.Compute': Executing statement ''RETURN TRUE;'' at ('.ASKTT_PreParse.Main', '11.3').
...."
Broker can't process namespace "urn:customs.ru:Envelope:ApplicationInf:1.0"
I've also tried other ways to get to this field, but...
Please, give me an advise, how to work it out!
Thank you in advance, Alexander |

Did you try removing the double "double-quotes " and replacing with single quote ?
'" urn:plant.ru:Envelope:ApplicationInf:1.0 '" |

DECLARE app NAMESPACE '"urn:plant.ru:Envelope:ApplicationInf:1.0"';
this would set app as
'urn:plant.ru:Envelope:ApplicationInf:1.0' and not urn:plant.ru:Envelope:ApplicationInf:1.0
try with single quotes as suggested by vsr... i am sure it should work well

Hi, thank you for your replies!

It was my first try. Using of single quotes, of course, is correct, but in this case broker try to build the following branch:
''InputRoot.XMLNS.http://www.w3.org/2001/06/soap-envelope:Envelope.http://www.w3.org/2001/06/soap-envelope:Header.urn:plant.ru:Envelope:ApplicationInf:1.0:ApplicationInf.urn:plant.ru:Envelope:ApplicationInf:1.0:MessageKind''
and it interprets "urn:plant" as another element. |
