Hello
Can anyone can help me with the following problem.
I have already done a search of the forum checked the link below but still no joy.
http://www.mqseries.net/phpBB2/viewtopic.php?t=26105&highlight=environment+parser
I have a SOAP encoded message which has within it the following from the trace:
(0x01000000)MiscTextFields = (
(0x01000000)MiscText = (
(0x03000000):index = '13'
(0x02000000): = '19940826145938'
)
(0x01000000)MiscText = (
(0x03000000):index = '14'
(0x02000000): = '1'
)
(0x01000000)MiscText = (
(0x03000000):index = '15'
(0x02000000): = '1060571'
)
(0x01000000)MiscText = (
(0x03000000):index = '5'
(0x02000000): = '5592220'
)
In the following compute node I have:
Create FIRSTCHILD of Environment DOMAIN 'XMLNS' Name 'Variables';
DECLARE InputMsg REFERENCE TO Environment.Variables.InputMsg;
Set InputMsg.XMLNS = InputRoot.XMLNS;
the result is loss of attributes in the InputMsg which I want to pass to a SOAP decode routine to create a message in the MRM to then do some mapping.
(0x01000000)MiscTextFields = (
(0x03000000)MiscText = '19940826145938'
(0x03000000)MiscText = '1'
(0x03000000)MiscText = '1060571'
(0x03000000)MiscText = '5592220'
What am I missing?
Thanks for any advice.

Well, let's deconstruct your ESQL.
The first line creates a child of Envrionment called Variables, that belongs to an XMLNS parser. At this point all is good!
| Code: |
| Create FIRSTCHILD of Environment DOMAIN 'XMLNS' Name 'Variables'; |
Now this line tries to create a reference to a field called InputMsg, which does not exist, as it has not been created yet. Therefore, after this statement InputMsg actually points to Environment itself. Oh dear, not what we wanted at all. This could have been caught by checking LASTMOVE on the reference after declaration.
| Code: |
| DECLARE InputMsg REFERENCE TO Environment.Variables.InputMsg; |
And finally this line now creates a copy of the incoming msg into an Immediate child of Evironment (called XMLNS), which does not belong to any parser, and so loses the attributes.
| Code: |
| Set InputMsg.XMLNS = InputRoot.XMLNS; |
In the code shown above, the reference is unnecessary, and can be removed, leaving the following code, which should do what was originally intended (untested).
| Code: |
Create FIRSTCHILD of Environment DOMAIN 'XMLNS' Name 'Variables';
Set Environment.Variables.InputMsg = InputRoot.XMLNS;
|
I hope this helps.
Regards,

Thank you, I'm further down the chain, I'm now losing them when I change the domain to MRM but first I will check my code isn't bug ridden!  |

I was a bit premature in my post.
Some attributes are carried forward and some aren't.
Tags such as this:
<SpecialField index="3"><code>C</code></SpecialField>
are ok in the trace:
(0x01000000)SpecialField = (
(0x01000000):index = (
(0x02000000): = '3'
)
(0x01000000)code = (
(0x02000000): = 'C'
)
But this below is not
<MiscText index="13">19940826145938</MiscText>
shown in the trace as:
(0x01000000)MiscTextFields = (
(0x01000000)MiscText = (
(0x02000000): = '19940826145938'
Can anyone tell me why that would be?
thanks
