hi vishnu,

Context Object:

Context objects are a simple alternative to XPath expressions for accessing the contents of a message. Take the following message instance as an example:

<InvoiceOut>

<customerData>

<address>

<name> ... </name>

<postalCode> ...</postalCode>

...

</address>

...

</customerData>

</InvoiceOut>

To access the content of the <postalCode> field, you would use the following expression in XPath:

/InvoiceOut/customerData/address/postalCode

Context Handling:

Context handling is an important technique to map complex scenarios in XI.

Message mapping in XI works by means of queues. A queue contains an entire XML instance of the source message. Depending on the hierarchy in the source message, different nodes and elements can be categorised into different contexts. All the nodes and elements that belong to the same parent node are said to be in the same context. Hence, the nodes and elements that belong to different parent nodes have to be separated by a context change

Hi vishnu,

<b>Context Object</b>

If u have multiple receiver system then to determine the reciever u can use context object.....

the alternative of context objetc is X-Path...

Check out these

Here is a scenario where context objects were used for BPM

Difference between context object and x-path:

<b>Context Handling</b>

XML contains some nodes and they follow some hierarchy. The level of a particular node in the hierarchy can be deremined by the context of the node in the hierarchy. Context handling is a technique where we use for manipulating these nodes and their hierarchy in the XML file/tree.

There are some standard given function to handle these kind of context handling issues.

Context Handling:- In XI during Mapping Queues are used...so as per the hireracy the elements in queue get inserted...

Example:

<A>

<Item>1</Item>

<Item>2</Item>

</A>

<A>

<Item>3</Item>

<Item>4</Item>

<Item>5</Item>

</A>

Queue for the same XML at the time of Mapping:

-

---

1

________________

2

________________

<b>

Context is inserted</b>

________________

3

________________

4

________________

5

________________

So if I want to remove this context I will use the Node Function called <b>removeContext</b> When I use it It will give me a queue like this.

________________

5

Context Object: Is use when there is a scnerio in which at Runtime you have to route the message to any receiver(based on the data of particular Element)

Example: I have an XML in which there is a TAG called <CustomerID>

Now If

<CustomerID> hasvalue 123 then I will send the message to System/Service A

If it has value other then this then I have to send it to toher System or Service

Hope this clear all your dought:-)

Thanks
