Hi,
wanted to check, can we do dynamic conversion from XML format to Structured String. means if we get xml message as an input, then at run time, we will select the Structured string template (based upon template identifier details in request message) and generate the Structured string.
IIB version using: IIB V10.0.0.1
Thanks. |

What do you mean by 'StructuredString'?
An example may well help.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

If you can map from the "template identifier details" to the name of a root element in a DFDL message definition, then you will have instructed IIB which message set to use.

Request message Example:
| Quote: |
<Employee>
<FirstName>FNAME</FirstName>
<LastName>LNAME</LastName>
<Salary>2000.30</Salary>
</Employee>
|
Scenario 1:
| Quote: |
Template 1 Details:
<Employee>
<FirstName length="10" type="String"></FirstName>
<LastName length="10" type="String"></LastName>
<Salary length="10" type="Number" precision="2"></Salary>
</Employee>
Response 1:
| Code: |
| "FNAME LNAME 00002000.30" |
|
Scenario 2:
| Quote: |
Template 2 Details:
<Employee>
<FirstName length="10" type="String"></FirstName>
<Salary length="10" type="Number" precision="2"></Salary>
<LastName length="10" type="String"></LastName>
</Employee>
Response 2:
| Code: |
| "FNAME 00002000.30LNAME " |
|
[/code]
Hope, this will give you clear idea. |

So a DFDL message.

We will try this approach and update you soon (if we have very specific templates).... |

yes, But we need to send DFDL message Dynamically based upon template design. |

Yes. I mentioned a method.

We are still discussing on this:
So far we have two approaches:
| Quote: |
Using Java code:
For dynamic template, we should be able to achieve it by java code to look each attribute inside the element, but this approach is good only for basic structure. This will be difficult, if we need to look nested element in template. |
| Quote: |
Using DFDL:
If we have very specific template then DFDL approach should be good, we should be able to implement it easily. But if templates are changing very frequently then it be difficult to maintain. |

You need to really analyze how often you expect your message formats to actually change.
If you're careful in how you build your message definitions, you can construct your DFDL messages such that you can just assign the input XML document tree to the output DFDL tree.

I believe: this requires code change, deployment effort, which again depends upon how frequently message format is changing. |

The other thing to think about is
"How complicated will the templates need to be" ?
If they are simply a matter of "Field A goes to Field 2, Field B goes to Field 1" and etc, then you could even just use a string (in a table property on a node).
But if your templates start having to make decisions based on data. Then that's really *code* and not *template*.
In v10 at least you can use shared libraries and only update and redeploy those.
