Hi,
Can anyone give me an optimised solution for my problem,
My catch flow is like this....
Compute -> MQOutput
Input to Compute is "Invalid XML Message" as BLOB and in compute im casting BLOB to Character and forming XML Message.
But the coverted message is something like this
"<a>..<asd>d</asd>..<zxc>d</zxc>..</a>..asd"
Note: I can use RCD but problem if incoming message is not in proper XML format. |

How large are the messages that you predict will be parsed by the message?

I often devide flows involving invalid XML messages into three steps
1) Copy the payload of the XML to the Environment.var.payload in the first compute node and only passes on the headers to the next compute node with CopyMessageHeaders();
2) Use one or more compute nodes to modify/build data where I build up the new XML structure in Environment.var.OutgoingXml using Environment.var.payload as input. While passing on the headers using CopyEntireMessage();
3) Reattach the new payload (Environment.var.OutgoingXml) to the headers, thus creating a complete XML message for the output.
In your case I guess you need to replace the < and > in the BLOB or after casting.

Maybe you're just reading the data wrong.

Hi,
This is my requirement (Error Handling)...
Input can be Valid or Invalid XML message
I ll be expecting MRM XML message. In case of parser exception control goes to Failure Terminal, where Im suppose to build error message which includes complete incoming message also.
But this is not possible since I need complete incoming message but I get message only till where it is parsed..
So I make it as BLOB and then use RCD to reset to MRM domain and do content and value validation (comput node) so that exception is thrown and can handle it in Catch Terminal.
Problem Im facing here is, if input message is not proper xml. I want that message to be embedded into my error message (xml format) as it is. I dont want to convert invalid xml to valid xml, want as it is.
Eg.,
Input: (Invalid XML Message)
<a>
<asd>d</asd>
<zxc>d</zxc>
</a>
asd
Output I have got after CASTing BLOB as Character
<SiebelMessage MessageType="Integration Object" IntObjectName="TP WMQ Error IO" IntObjectFormat="Siebel Hierarchical" ProcessName="DUMMY" ProcessVersion="1.0" ProcessType="CONNECTOR">
<ListOfTPWmqErrorIo>
<WmqError>
<DataReferenceLanguage>ENU</DataReferenceLanguage>
<InboundMessage>
<ListOfInterfaceAccountIo>
<a>..<asd>d</asd>..<zxc>d</zxc>..</a>..asd
</ListOfInterfaceAccountIo>
<ErrorMessage>
<ErrorType>RecoverableException</ErrorType>
<ErrorText>Caught exception and rethrowing:ImbRecoverableException caught from worker->parse.:FI Handler Error: The Message ID that was received from the worker was not the same as the ID Previously specified.:SiebelMessage:</ErrorText>
<ErrorNumber>5337</ErrorNumber>
</ErrorMessage>
</InboundMessage>
<ErrorCode>E001</ErrorCode>
<MessageReferenceLanguage>ENU</MessageReferenceLanguage>
<Name>ACCOUNT V2.1 - 2.1 - 1-1VRNT - ASA101</Name>
<ProcessedDate>2006-09-07 16:43:14.557</ProcessedDate>
<ReceivedDate>2006-09-07 16:43:14.557</ReceivedDate>
<TransferredDate>2006-09-07 16:43:14.557</TransferredDate>
<Type>Connector</Type>
</WmqError>
</ListOfTPWmqErrorIo>
</SiebelMessage>
Thanks in advance... |

That's not an accurate description of what's happening. You should have said
| Quote: |
| Output I have got after CASTing BLOB as Character, THEN adding the resulting string into the message tree, THEN serializing the message tree as XML |
When message broker writes XML, it automatically escapes anything which looks like markup, or which might cause a problem to an XML application ( see http://www.mqseries.net/phpBB2/viewtopic.php?t=31534 ).
That is why you are seeing the character entities < and > in place of your < and >.
If you want to embed XML within XML, the correct way to do that is to enclose it in CDATA tags. e.g.
| Code: |
<embeddedXML><![CDATA[<a><asd>d</asd><zxc>d</zxc></a>]]></embeddedXML>
|
You can instruct the XML/XMLNS/XMLNSC parsers to do this - just search for 'CDATA' in the docs. Currently, it's not easy to persuade the MRM domain to write CDATA sections. |

Why are you posting on a thread which has seen no activity for five months?
XML.AsisElementContent should only be used as a last resort. I don't believe this scenario requires it. |
