Hi,
Iam trying to change the data in a field in a MQRFH2 header.
I am using the following code
SET OutputRoot.MQRFH2 = InputRoot.MQRFH2
SET OutputRoot.MQRHF2.Field = 'Hello'
However, in the output message I get (Field dt="Hello"/)
when I want (Field dt="string")Hello(/Field)
Any suggestions ?
By the way had to replace the chevrons with brackets in this post to display msgs

Hi,
the capabilities of the MQRFH2 parser
are limited. Could you please describe
your problem in a bit more detail, I'm
not quite sure I understand what you are
trying to do.
Some background:
MQRFH2 has fix length section and variable
length XML section. Fixed length header fields should accessed by e.g.
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR';
Variable Length XML can *only* by string elements.
You are recommended to put all user defined
data elements into the section
OutputRoot.MQRH2.usr.xxx
To generate the following XML Syntax
data
use
SET OutputRoot.MQRFH2.usr.field = 'data';
SET OutputRoot.MQRFH2.usr.field.(XML.attr)type = 'String';
NOTE:
You can insert non-char data into the name-value section of MQRFH2, but you will get
a parser exception when you try write the message to queue.

Hi again,
let's try again to the XML right
<usr>
<Field type='String'>data</Field>
</usr>
by disabling HTML in the post

Cheers.
I got this to work by deletin the field first.
ie.
SET OutputRoot.MQRFH2.usr.field = NULL
Then I did
Set OutputRoot.MQRFH2.usr.(XML.tag)Field.(XML.attr)dt = 'String';
Set OutputRoot.MQRFH2.usr.(XML.tag)Field = 'xxxxxx';
Not sure if this is the best way to do it, but it works. |
