hey guys can u please help me
i'm receiving a message with mutli ref fields in it
i'm not able to parse it or get the values from the fields

the input message is :

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</soapenv:Body>
</soapenv:Envelope>


i wana it to be some thing like :

- <getAccountListReturn xsi:type="ns:InPrecheckResponse">
<wsStatusProcess xsi:type="xsd:int">0</wsStatusProcess>
<accountId xsi:type="xsd:long">12</accountId>

<authoAmount xsi:type="xsd:long">0</authoAmount>
<balModDate xsi:type="xsd:long">0</balModDate>
<balance xsi:type="xsd:long">12</balance>
<currency xsi:nil="true" />
<executionStatus xsi:type="xsd:int">0</executionStatus>
<expiryDate xsi:type="xsd:long">0</expiryDate>
<ownerId xsi:nil="true" />
<transactionId xsi:nil="true" />
<transparentData xsi:nil="true" />
</getAccountListReturn>
</ns:getAccountListResponse>

What happens when you try? Error codes, messages, arrested by the FBI, what?

We need some clues here if we're going to help.

Are you declaring the namespaces and using them in your references? MOst of the times the error is in defining the reference in case of namespace aware messages. If you cna share the esql you have written you will be helped quickly.

Cheers,

I think nemo101 wants the WMB XML parser to automatically link
Code:
 <wsStatusProcess href="#id1" />
with
Code:
 <multiRef id="id1" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="xsd:int" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">200</multiRef>
to produce a message tree containing the parsed version of
Code:
 <wsStatusProcess xsi:type="xsd:int">200</wsStatusProcess>
by matching the href attribute values with the id attribute values.

None of the WMB XML parsers can do this trick, but it is straightforward to write some ESQL ( or XPath, if in a Java Compute node ) to do the job.

Kimbert you got this right thank you for your support

my ESQL to parse this (href - multiref) standard was :

Code:

SET OutputRoot = InputRoot;
      /*
      Parse Input Message if Multi Ref
      I/p = XMLNSC.null1:getAccountListResponse
      O/p = XMLNSC.null1:getAccountListResponse -Well Formated-
      */
      DECLARE I INTEGER 1;
      DECLARE J INTEGER;
   
      SET OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn = InputRoot.XMLNSC.null1:getAccountListResponse.multiRef[1];
      SET J = CARDINALITY(OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn.*[] );
   
      DECLARE temphref character;
      DECLARE tempval CHARACTER;
      
      WHILE I <= J DO
         
         IF (OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn.*[I].href is NOT null ) THEN
            set temphref =  SUBSTRING( OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn.*[I].href FROM 2) ;
            
         call Get_Multi_Ref( temphref , OutputRoot.XMLNSC.null1:getAccountListResponse , tempval );
         
         set OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn.*[I]  = tempval;
         set OutputRoot.XMLNS.null1:getAccountListResponse.null1:getAccountListReturn.*[I].href = null ;       
         
         END IF;

         SET I = I + 1;
      END WHILE;
      
      -- XMLNS Worked only as a temp variable
      set OutputRoot.XMLNSC = null;
      set OutputRoot.XMLNSC = OutputRoot.XMLNS;
      set OutputRoot.XMLNS = null;      



and the code for the procedure Get_Multi_Ref is :
Code:

CREATE PROCEDURE  Get_Multi_Ref
                    ( IN href CHARACTER,
                     IN InBody REFERENCE ,
                     out fValue CHARACTER  )
   BEGIN
      DECLARE I INTEGER 1;
      DECLARE J INTEGER;
      
      SET J = CARDINALITY ( InBody.multiRef[] );
      
      while I <= J DO
         if (InBody.multiRef[I].id = href ) THEN
            SET fValue = FIELDVALUE(InBody.multiRef[I]) ;
            SET I = J ; -- Exit the loop
         END IF;   
         SET I = I +1;
      END While  ;
      
   END;


i extracted the envelope my self by esql, You know what the version 6.2 node soap extract is generating exceptions when supplied with a message with a multiref portion.



this code working fine for now but as you can see it's not generic and with every different message i'll have to change it again
i was wondering if there is a generic way to parse this href-multiref portion ?


thank you all for your support.

I'm not going to write your ESQL for you, but I've got a couple of suggestions:
- Copying OutputRoot.XMLNS to OutputRoot.XMLNSC is both weird and dangerous. I don't know why you are doing it, but I suggest that you find an alternative solution.
- You rarely need to write a counted loop in ESQL. References do a better job, and are more elegant.
- Get_Multi_Ref will do the job, but it will not perform very well. You could replace the entire procedure with a single SELECT statement.
