Visual Mapping for Generic Type

Question

I have generic message type:
-Row (Occurences 1..unbounded)
--Field (Occurences 1..unbounded)
I want to use this type for all csv files(with different amount of fileds). But how can I map this type on my own type in Visual Mapping? Is it possible?
For example:
  <row>
    <field>111</field>
    <field>222</field>
  </row>
Result MT:
   <user>
     <name>111</name>
     <number>222</number>
   </user>

Hi Sergey,
This is possible in message mapping using user defined functions but needs lot of hardcoding in the code interms of position of the each field i.e
In your message queues the <field>111</field> will be in  position1 and <field>222</field> in position2. so simply map content of position1  <name>111</name> and content of position2 to <number>222</number>. Simple java code in user defined function can do this.
But there is risk involved since the mapping is position based all the fields in the source must exist(at least blank value).
consider input message with 3 fields
<row>
<field>111</field>
<field>222</field>
<field>333</field>
</row>
and target
<user>
<name>111</name>
<number>222</number>
<number>333</number>
</user>
If suppose your second field <field>222</field> does'nt exist then in your message queue <field>333</field> will move to second position henece your mapping might get messed up and fail.
