Hi,

Xpath :

Yes, the main purpose is it to identify.

Assume an option to have "and" or an "or" condition if required ( Example if want to check if "x" and "y" is satisfied or it you wanna check if "x" or "y" is satisfied, this can also be acheived)

Hi,

<i>XPath is a language for finding information in an XML document</i>. It is used to navigate through elements and attributes in an XML document.So thru this you can read the element and point out the element to work on, As you know in XI all the messages are processing with xml message. There is a need to navigate the xml document for many reasons. For e,g to do conditional routing i.e based on the payload data field you need to route into some receiver in that case you need to access that element. Totally there is a need to access xml element at any point of time.

<i>The payload is the actual contents (business data) of a message in the Exchange Infrastructure.</i> - from sap help

In sweet and simple one line definition, we can say : XI payload is actual business data to be exchanged , which is displayed in XML format.
