All,
Is it possible to find the postion of a string in an array.?

Basically I have a requirement to group items together based on a field.
I am mapping an Idoc to XML.
Current output:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<Payload>
<BatchRegister>
<Registration>
<Info Name="test1">
</Info>
<Item Num="A1"/>
</Registration>
<Registration>
<Info Name="test1">
</Info>
<Item Num="A2"/>
</Registration>
<Registration>
<Info Name="test1">
</Info>
<Item Num="A3"/>
</Registration>
<Registration>
<Info Name="test2">
</Info>
<Item Num="A4"/>
</Registration>
<Registration>
<Info Name="test2">
</Info>
<Item Num="A5"/>
</Registration>
<Info Name="test3">
</Info>
<Item Num="A6"/>
</Registration>
</BatchRegister>
</Payload>

Expected output:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<Payload>
<BatchRegister>
<Registration>
<Info Name="test1">
</Info>
<Item Num="A1"/>
<Item Num="A2"/>
<Item Num="A3"/>
</Registration>
<Registration>
<Info Name="test2">
</Info>
<Item Num="A4"/>
<Item Num="A5"/>
</Registration>
<Info Name="test3">
</Info>
<Item Num="A6"/>
</Registration>
</BatchRegister>
</Payload>

I am storing the condition field to env variable every time and trying to find the position of the string in that array. If I am able to find its position, I can then set the index to that position and set the output.

Correct me if this is the good approach and assist me in this.

There are no arrays. There are only logical message trees made up of nodes, or list or rows.

The only notion of a "position" for an item in a logical message tree is relative to it's parent and it's siblings.

You will need to write code to walk the tree and gather the information you need.

You might consider using a logical message tree in Environment that gathers data as children of nodes named for the Info value.
