Problems with Xpath

[former_member118690]

Hi All,

i'm new in XI-Xpath, i read the main blogs here in SDN community but i still have some problems with my condition.

My scenario is the following, i have the following messagge and i need to send it to different systems according to the "sender" field

<?xml version="1.0" encoding="UTF-8"?>

<TrainRunningInformationMessage>

<MessageHeader>

<MessageStatus/>

<MessageReference>

<MessageType MessageTypeCode=""/>

<MessageNumber/>

<MessageDateTime/>

</MessageReference>

<Sender>

<Recipient/>

I need that the receveir is system A if the sender='a' and 'recipient='b', i can do it using the equal and AND condition but i need to use the EX operator (beacuse this is just a part of a bigger condition).

I tried with

(/p1:TrainRunningInformationMessage/MessageHeader/Sender = 'a' and /p1:TrainRunningInformationMessage/MessageHeader/Recipient = 'b' EX ) but it's not working, can anyone help me?

Thz a lot

make this blog as your reference - /people/shabarish.vijayakumar/blog/2006/06/07/customise-your-xpath-expressions-in-receiver-determination

a bit confused about your requirement...

/p1:TrainRunningInformationMessage/MessageHeader/Recipient = 'b' EX

You cannot have this declaration.....you need to define it separately if you want to check if Recipient = b and if Recipient node exists then use the EX function.....cannot be clubbed in the same line

Sorry,

i forgot (), my condition is ((/p1:TrainRunningInformationMessage/MessageHeader/Sender = 'a' and /p1:TrainRunningInformationMessage/MessageHeader/Recipient = 'b' ) EX )

[former_member200962]

can you tell me why for you have used EX and what is it supposed to do in your scenario.....

[former_member118690]

I need the following:

if (sender = 'a' and receiver = 'b') or (sender = 'a1' and receiver = 'b1') the messagge has to be sent to system A

if (sender != 'a' or receiver != 'b') and (sender != 'a1' or receiver != 'b1') the messagge has to be sent to

system B

I'm able to create the first condition with standard condition editior functions but i cannot to do the second one so i want to use xpath expression.

thanks for the help

if (sender != 'a' or receiver != 'b') and (sender != 'a1' or receiver != 'b1')

for this you need to refer the blog by Shabarish...it deals with these conditions...

Hi Aldo,

very easy.

Just use the first condition!

In your receiver determination you will see on the bottom a checkbox:

"If no Receiver is Found, Proceed as Follows"

Enter: "Select the Following Receiver"

Thats it.

I solved the problem, i wrote a / where it was not needed (before [).

I could not use "Error Messagge" in the case of "If no receiver is found Procedd as follows-->error messagge" because in the case that the first condition is not satisfied i need to send a messagge created by myself and not a standard one.

Thanks all of you for the support

Bye Aldo
