Hi All,

I'm trying to map from a flat structure where each system has it's own node.

Code:

<source>
<system_ABC>
   <date>9/5/12</date>
   <status>ON</status>
</system_ABC>
<system_DEF>
   <date>2/5/12</date>
   <status>OFF</status>
</system_DEF>
</source>


to a single repeating element

Code:

<target>
<system>
   <date>9/5/12</date>
   <status>ON</status>
   <systemCode>ABC</systemCode>
</system>
<system>
   <date>2/5/12</date>
   <status>OFF</status>
   <systemCode>DEF</systemCode>
</system>
</target>


Is there a way to do this using a WMB7 mapping node?
Seems like it should be easy to do, but I'm just a little stuck atm

Well, let's see:
You need a function to read the tagname
You need a function to transform the tagname
you need a function to set / replace the tagname
You need to map the content accordingly....

This part is easier to do in ESQL than in a mapping node as the tagname is not predefined...

Have fun

I agree with fjb_saper - ESQL is the way to go here. Remember to use REFERENCE variables when looping.
