mapping problem

[Former Member]

I have Message A and B. The structure is as below

Message A:

|--option 0..unbound

|----item 2..2

|------comments string 1..1

Message B:

|--header 0..unbound

|----text string 1..1

now i just want to map

option->header

(the second item's)comments->text

because the occurrence "item" in message A is 2, i just want to get the "comments" of second item.

the input:

<option>

<item>

<comments>1</comments>

</item>

<item>

<comments>2</comments>

</item>

</option>

<option>

<item>

<comments>3</comments>

</item>

<item>

<comments>4</comments>

</item>

</option>

the out put i want is:

<header>

<text>2</text>

</header>

<header>

<text>4</text>

</header>

How should i do?

Thank you for your reply

Hi Rensheng luo ,

Please try the following,

Option-->Header

Coments(with context as option)-->index-\

............................................................|StringEquals-->|if_\

-

---

Constanat(2)./

-

---

|........|-->text

-

---

>Coments(with context as option)|then/

Hi,

u can write a user defined function where

first u get the number of occurance of ITEM node,

then run a for loop with index starting with 2 and increment it with 2(for i=2,i<=length of number of item node;i+2)

so u can get every second occurance of item and map it with the target.

Hi Rensheng,

This can be done by writing a user defined function while doing your graphical mapping.So there you can write the logic to input the comments and return only the second comments value to the target.

I think u can use count(node function) to know the occurance of item, and map comment -text with if count=2 to take second occurance.

Hope this solve ur problem
