I have a message flow with structure
HTTPinput>SOAPExtract>XMLT1>ResetContentDescriptor1>Compute>XMLT2>ResetContentDescriptor2>SOAPenvelope>HTTPReply
The domain in HTTPinput is XMLNSC and ResetContentDescriptor1 resets it to xml and ResetContentDescriptor2 resets it to XMLNSC. The problem is that all my nodes return expected output when I use an MQinput, MQoutput but when I use HTTP/SOAP nodes the output from XMLT2 or ResetContentDescriptor2 is not completely parsed. The user trace clearly shows that only a part of the XMLT2 output message has been parsed.
Below is the usertrace that captures this incomplete parsing

Please tell me that you have a really good reason for doing this - it sounds like a bizarre thing to do. |

The XMLT transformation does not appear to work while in XMLNSC.As for the main parsing issue, I have resolved it now. When you drag a WSDL "the create new SOAP envelope" is unchecked for the SOAPEnvelope node. I checked it and the webservice client could now access the output.
Thanks,

Can you be more specific about the problem? I know for a fact that XMLNSC and the XMLT node can work together.
Either way, if you really need to use something other than XMLNSC two comments apply:
1. Don't use XML, use XMLNS
2. Why not use XMLNS throughout the flow? Switching XML domains is bad for performance and doing it twice is even worse. |

My understanding of the issue was incorrect. The issues does not seem to be with regards to XMLNSC or XML but the output domain of the message after transformation. When I try to use a compute node after the the XMLT node, the compute node does not appear to parse where as when I Introduce ResetContentDescriptor, It parses correctly and the flow moves ahead. So the question should rather be WHAT IS THE MESSAGE DOMAIN OF THE OUTPUT, POST TRANSFORMATION?I have illustrated below the scenario using trace which led me into the above conclusions
MQInput(XMLNSC or XML)>XMLT>XMLT>MQOuput::message parsed accurately between XMLT>XMLT
MQInput(XMLNSC or XML)>XMLT>Compute(which uses InputRoot.XMLNSC or XML.*)>XMLT>MQOuput::Unable to parse at Compute.
MQInput(XMLNSC or XML)>XMLT>ResetContentDescriptor(XMLNSC or XML)>Compute(which uses InputRoot.XMLNSC or XML.*)>XMLT>ResetContentDescriptor(XMLNSC or XML)>MQOuput |

Doesn't the documentation say somewhere that the output of the XMLT node is in the BLOB domain ??

oh yes, it does, in the section "Deciding which nodes to use" but not where I thought it ought to be... >Built in nodes>XMLT.
Thanks |
