Hi All,
WINDOWS 2000, WMQI Broker V 2.1, CSD 8
Here is my input file.
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<A><Dipu><abcd>dasdas</abcd></Dipu></A> |
Here is my ESQL
| Code: |
| SET OutputRoot.XML.WfMessage.StandardError.SourceData.XML.CDataSection) = CAST(ASBITSTREAM(InputBody.A.Dipu.[1] OPTIONS FolderBitStream) AS CHAR CCSID InputRoot.MQMD.CodedCharSetId ENCODING InputRoot.MQMD.Encoding); |
This is the output
<WfMessage>
<ProcessTemplateCreateAndStartInstance/>
<StandardError>
<SourceData><![CDATA[<abcd>dasdas</abcd>]]></SourceData>
</StandardError>
</WfMessage>
This is what I am expecting. so far no problem.
But if I give the following input
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<A>
<Dipu>
<abcd>dasdas</abcd>
</Dipu>
</A> |
it does not work. The message is being rolled back.
please tell me how I can fix the problem. |

After tracing I got this

Hrm.
Try putting <A> on the same line as <xml...> and see what it says.

Jeff,
Please see the following input which are working fine.
Input 1:
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<A><Dipu><abcd>dasdas</abcd>
</Dipu>
</A> |
Input 2:
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<A>
<Dipu><abcd>dasdas</abcd>
</Dipu>
</A> |
But when I insert an CRLF after <Dipu>
then it creates an exception i.e when my input like
<?xml version="1.0" encoding="UTF-8"?>
<A>
<Dipu>
<abcd>dasdas</abcd>
</Dipu>
</A>
Please see the above exceptionlist. It is now changed. The previous was wrong.
Thanks for quick reply. |

Okay, this makes a lot more sense now.
You're asking for the first child of Dipu (ASBITSTREAM(InputBody.A.Dipu.[1] ).
When you have CR/LFs in your XML, then they are parsed and stored as elements in the logical message tree. So when you put CR/LF after <Dipu>, you are making the CR/LF element to *be* the first child of <Dipu>.
And a single element is not a folder, and so ASBITSTREAM is complaining.
You should be able to qualify InputBody.A.Dipu.[1] in some way to skip anything that's not an XML.Element.
Or at least, you should be able to create a reference that points to the first XML.Element child of Dipu. And then pass that to ASBITSTREAM.
Or if worst comes to worst, you can parse out CR/LFs in various ways.

Not tested:
| Code: |
| InputBody.A.Dipu.(XML.Element)*[1] |
