Splitting file depends upon no of occurence of element

Question

Hi
I have the scenario as follows where i need to split the file depends upon number of occurences of element e1 .
I have input xml file having structure as follows:
<ROOT>
<root1 attribute>
   <field1> </field1>
   <e1>
       <field2> ....</field2>
   </e1>
    <e1>
        <field2> .......</field2>
   </e1>
</root1>
<ROOT>
<u>element e1 has "1 to unbounded" occurence.</u>
I would like to have output file structure as
<ROOT>
<root1 attribute>
   <field1> </field1>
   <e1>
       <field2> ....</field2>
   </e1>
</root1>
<ROOT>
the key thing for every occcurence of element e1, the output file will be generated and
attribue value of root1 and element position will  be included in the file name .
Thanking you in adbvance.

Hi Piyush,
Create a message mapping for the spliting you want.
Under <b>Messages</b> tab
<b>Source Message:-</b> Your message type name example
<ROOT>
<root1 attribute>
<field1> </field1>
<e1>
<field2> ....</field2>
</e1>
<e1>
<field2> .......</field2>
</e1>
</root1>
<ROOT>
<b>Note:- Occurence is 1</b>
<b>Target Message:-</b> your message type name example
<ROOT>
<root1 attribute>
<field1> </field1>
<e1>
<field2> ....</field2>
</e1>
</root1>
<ROOT>
<b>Note:- Occurence is 0 to unbounded</b>
In the Design tab do your graphical mapping one to one mapping
<b>Note:- <e1> of the source element (0 to unbounded) should be mapped to <ROOT> of the target element (0 to unbounded).</b>
Then you can test your mapping by giving your test data
<b>While Creating the Interface mapping please make sure that the target interface occurence is <i>0 to unbounded</i>.</b>
that's it you are done with it.
Make sure in BPM use <b>transformation step</b> to convert the source to target messages and use <b>multiline container element</b> and use <b>foreach block</b> to catch the message
