Hi,
Have anyone managed to parse DataObjects from bytestream with ESQL?
If I try following:
1) Get iDoc from SAP with generic SapGenericIDocObject
2) SET OutputRoot.BLOB.BLOB = CAST(InputBody.*:SapGenericIDocObject.*:IDocStreamData AS BLOB); and forward message to MQ
3) Get Message with MQInput (BLOB parser set)
4) Parse bytestream with following ESQL
| Code: |
CREATE LASTCHILD OF OutputRoot DOMAIN 'DataObject' parse(InputRoot.BLOB.BLOB ENCODING InputRoot.Properties.Encoding CCSID InputRoot.Properties.CodedCharSetId SET 'x' TYPE 'x' FORMAT 'SAP ALE IDoc' OPTIONS ValidateImmediate);
|
I get weird XML parsing errors.
If I set MQInput -node to parse message with same settings it parses correctly without any problems.
Ok, I saw from InfoCenter mentions that If Dataobject will be directed somewhere else that adapters It will use XMLNSC for serialisation. Perhaps the same is true for parsing (except MQInput that seems to understand IDoc bytestream directly)?

| Marko, I haven't tried it myself, but what if you set FORMAT 'DataObject' in your statement. FORMAT is usually what tells the Broker which parser to use. |

Thanks NealM,
I tested that and got the same XML -parsing errors. But it was expected result, because as far as I know FORMAT is used to select wire-format not the parser.

Sorry, my bad. I'm curious though:
1. If you just unBLOB the input string to Char, is it truly an IDOC (did the original CAST to BLOB do just that or perhaps turn it into XML in serializing it)?
2. What would you get if you specified an XMLNSC domain on the MQinput node?
3. Does a ResetContentDescriptor work on the BLOB or also give you weird parsing results? |
