Dear all,
Can any one help me regarding the below.
I have scenario like
InputNode---->ComputeNode1---->ComputeNode2---->OutputNode
In ComputeNode1, ESQL code looks like below
--------------------------------------------------------------------------------
| Code: |
DECLARE ns_tw_rep NAMESPACE 'http://www.eample.com/xml/ListofTaxExemptInquiry';
SET Environment.Variable.Seibel_NS = ns_tw_rep;
SET OutputRoot.XMLNSC.ns_tw_rep:SiebelMessage.(XMLNSC.NamespaceDecl)xmlns = ns_tw_rep;
SET OutputRoot.XMLNSC.ns_tw_rep:SiebelMessage.ns_tw_rep:Exemptions.ns_tw_rep:Document.ns_tw_rep:LegalEntity = 'Exception Message';
SET OutputRoot.XMLNSC.ns_tw_rep:SiebelMessage.ns_tw_rep:Exemptions.ns_tw_rep:Document.ns_tw_rep: Source = 'Customer'; |
output of compute node1
--------------------------------------------------------------------------------
<SiebelMessage xmlns="http://www.eample.com/xml/ListofTaxExemptInquiry" MessageId="" IntObjectName="123" IntObjectFormat="Hierarchical">
<Exemptions>
<Document>
<LegalEntity>Exception Message</LegalEntity>
<Source>Siebel Customer</Source>
</Document>
</Exemptions>
</SiebelMessage>
--------------------------------------------------------------------------------
In computeNode2 code looks below
---------------------------------------
| Code: |
DECLARE ns1 REFERENCE TO Environment.Variable.Seibel_NS;
SET OutputRoot.XMLNSC.ns1:SiebelMessage.(XMLNSC.NamespaceDecl)xmlns = ns1;
SET OutputRoot.XMLNSC.ns1:SiebelMessage.ns1:TestMessage = InputRoot.XMLNSC.ns1:SiebelMessage.ns1:Exemptions.ns1:D ocument.ns1:LegalEntity ; |
I am getting error while tracing , Failed to parse becuase path 3 doesn't exist.
if i do the code in Compute Node2 like below, it works fine
--------------------------------------------------------------------------------
| Code: |
DECLARE ns1 NAMESPACE 'http://www.eample.com/xml/ListofTaxExemptInquiry';
SET OutputRoot.XMLNSC.ns1:SiebelMessage.(XMLNSC.NamespaceDecl)xmlns = ns1;
SET OutputRoot.XMLNSC.ns1:SiebelMessage.ns1:TestMessage = InputRoot.XMLNSC.ns1:SiebelMessage.ns1:Exemptions.ns1:D ocument.ns1:LegalEntity ; |
Could you please help me in this regard. one more intresting thing, its works well for OutputRoot,
SET OutputRoot.XMLNSC.ns1:SiebelMessage.(XMLNSC.NamespaceDecl)xmlns = ns1;
in tracing it shows, assigns namespace. but why its not working for InputRoot[code] |

An ESQL namespace constant must be declared like this:
| Quote: |
| DECLARE ns_tw_rep NAMESPACE 'http://www.eample.com/xml/ListofTaxExemptInquiry'; |
You cannot use a reference to a CHARACTER variable in place of a proper namespace constant, as you are attempting to do in Compute2:
| Quote: |
| DECLARE ns1 REFERENCE TO Environment.Variable.Seibel_NS; |
You may be able to use the {} syntax to evaluate Environment.Variable.Seibel_NS, like this ( not tested ):
| Code: |
| SET OutputRoot.XMLNSC.{ns1}:SiebelMessage.{ns1}:TestMessage = InputRoot.XMLNSC.{ns1}:SiebelMessage.{ns1}:Exemptions.{ns1}:D ocument.{ns1}:LegalEntity ; |

Hi,
How about declaring these reusable namespaces at the schema level in other word in own ESQL -file? I'm remembering that it could work also with that way.

Kimbert, could he use following:
| Code: |
| DECLARE ns1 NAMESPACE Environment.Variable.Seibel_NS; |
Of course this means that for the duration of the message this namespace ns1 would be locked to the value given at declare time...
This could potentially be alleviated with the scope in which the namespace is declared and used...

Hi Kimbert,
Its working now if i use in curly braces like

Thanks a lot.
Hi fjb_saper,
DECLARE ns1 NAMESPACE Environment.Variable.Seibel_NS;

Syntax error. Valid options include: OVERLAY SUBSTRING TRIM |
