You work in an international company which is named TXTWIN. And you’re in charge of the company network and use Microsoft BizTalk Server 2006 R2.
The XML message files is generated by the Accounting, Customer Relationship Management, and Asset Management systems to a central file directory on the network. In the XML message files, there’s data which will be sent to other systems in terms of message type. You develop an orchestration to send the messages to the other systems. The message type is specified in the fourth node of the message. But the message adheres to different schemas. What should you do to identify the message type for each message?

A.
In the orchestration of type System.Xml.XmlDocument, you should create a message.
Read the fourth node, and set the message type by using an Expression shape and an XPath statement.

B.
You should read through each line of the file by using a Loop shape and an Expression shape with a StringBuilder object.
Before you perform this, in the orchestration of type System.String, you should create a message.

C.
You should assign the RawString to a new message of the message type by using a Message Assignment shape.
Before you perform this, you should create a custom pipeline to receive messages of type XlangCustomFormatters.RawString.

D.
Assign the Stream object to a new message of the message type by using a Message Assignment shape.
Before you perform this, you should create a custom pipeline to receive messages of type System.IO.Stream.
Parse the Stream object by using a DataReader object.
