Message Assignment
|
|
|
| I am playing around with some orchestration fuzz.
I cant understand why i cant change the message biztalk is sending out i
have tried all sorts of things i.e:
I initalize msgShipping which is the .net xmldocument with the
customerparams (so i wont get i compiler error)
afterwards i try to change it but nothing happens, the original message
comes out (customerparams).
It is like need some commit command or something what is going on.
msgShipping = Customer_Param;
msgShipping.RemoveAll();
msgShipping.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
"<title>Pride And Prejudice</title>" + "</book>");
XmlNode = msgShipping.DocumentElement;
//Create a new title element.
XmlElement = msgShipping.CreateElement("title");
XmlElement.InnerText="The Handmaid's Tale";
//Replace the title element.
XmlNode.ReplaceChild(XmlElement, XmlNode.FirstChild);

| Hello mm,
A BizTalk message is immutable, meaning it cant be changed, that is why you
cant see anything different in the message, regardless of its type.
You might consider a message assignment to a new message name, or using a
variable of type XmlDocument to update the message and then assign it back.
Cheers,
BA

The idea is that you can only modify the message when constructing it.
but you are not limited to a single operation while constructing it.
You do, however, have to start with an existing message unfortunately.
so - one option is to map an existing message to your new message, even
if the mapping does nothing essentially.
then you can use a second shape in the message construction container to
modify your message with the correct contents.
another options is to start with an XmlDocument instantiation inside a
message assignment shape. you can have code to load an Xml instance
(hard coded, or from a file or any other source) to instantiate the
XmlDocument with the correct contents.
like with he map option you can then use whatever code you need to
modify the loaded Xml as long as you do it within the message
construction container.
Hope this helps

| Okay maybe i am not too handy in this:
I wrote this in an expression shape.
all i want to do is that the outcome should look like <book xmlns='test' and
the other attributes><xml></></>
Xmldoc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" + "<title>Pride
And Prejudice</title>" + "</book>");
varXMLattrib = Xmldoc.CreateAttribute("xmlns");
varXMLattrib.Value ="test";
Xmldoc.Attributes.Append(varXMLattrib);
it comes with an error that says object not set to an instance of an object.
could someone tell me how to write that code in an expression shape!
cheers!

From the error message it is not clear which statement cause the
problem, assuming that Expression2 is the shape in which you've placed
these lines and that there are no other statements I would add some
trace information to try and figure out which object is not being created.
One thing to check is whether you are using the default constructor of
XmlDocument when declaring XmlDoc.
