Debatching(Splitting) XML Message

Debatching(Splitting) XML Message - BizTalk 2010

July 27, 2020

In this post we will walk through the process of debatching xml message using Biztalk.

Scenario:

We receive many item information but its wrapped(Enveloped) , so to process each item we need to unwrap it ( remove envelope and split individual Item message.

Below is what we receive(Input) :
<ns0:Items xmlns:ns0="http://TestingSchemas.ItemEnvelope">
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_0</ID>
<Name>Name_0</Name>
<Quantity>100</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_0</ID>
<Name>Name_1</Name>
<Quantity>200</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_2</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_3</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_4</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_5</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_6</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_7</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_8</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
<ns1:Product xmlns:ns1="http://TestingSchemas.Item">
<ID>ID_9</ID>
<Name>Name_2</Name>
<Quantity>300</Quantity>
<UnitPrice>100</UnitPrice>
</ns1:Product>
</ns0:Items>

But we want(Output) :

<ns0:Product xmlns:ns0="http://TestingSchemas.Item">

</ns0:Product>

<ns0:Product xmlns:ns0="http://TestingSchemas.Item">

</ns0:Product>

Allright , lets see how we do it:

1. Create schema - document schema

2. Create the wrapper - Envelope Schema

Name the root node, I have named it Items.

Set the property "Envelope" as Yes , as this schema will be used as envelope and this is the property which helps disassembler to recognize it.
So far good , envelope schema is ready but what about the document which will be wrapped.

In the Property window select "Imports" and click on the ellipsis
You will get Imports wizard pop-ed out .
Click on add and select the document schema which we created in step 1.(Here it is Item schema)

Click on the "Items" and go to property window and select the property Body XPath and set it to
3. Now create a Receive port which will receive enveloped message(ItemEnvelope Type) .
4.Now create a Send port which will send individual xml message (Item Type)
- Add Filter (this creates subcription ) : BTS.ReceivePortName == ReceiveItem
- After splitting the message , the pipeline would submit individual Item Messages and as we are creating subscription , all the messages submitted by ReceiveItem port will be picked by SendPort
5. Now lets test, I will drop a envelope message at receive location which we saw at start . So I should be getting 10 individual xml message at the destination location:

6.Did we really got the messages split-ted:

Will keep on posting as an when I find something to share!!!!!!!!!!!!
