Dynamically rename the root node of XML based on the child elements

Question

Hi Gurus,
Is there any way to rename the root node of the resultant XML after a mapping based on the child elements.
For ex:
consider the following resultant XML after mapping
<result>
<element1> </element1>
<result>
if the element1 is <type> then the output should be
<category>
<type> </type>
</category>
elseif the element1 is <character> then the output should be
<property>
<character> </character>
</property>
Let me know how to do this, either in XSLT or in Graphical mapping.
Thanks,
Prabu

Hi, Prabu:
In this case, I am suggest you have Src and Tar Message.
I am suggesting you create another type of message using key / value pair as I suggested, e.g. called Mid Message.
My solution for you is to have two message mappings:
1. Src -> Mid
2. Mid -> Tar.
In first mapping, you have no control of the structure, but you can map it to Mid structure:
e.g.
  if Type node Exist, then map 'Type' to Key, as Key/Value can be creatd under a parent node with 0:1 Occurrence.
  saying item.
   in this case, a new item created.
If you think of this way, any xml file can be represted in this way:
   <Employee>
      <Fname>David</Fname>
      <Lname>Miller</Lname>
   </Employee>  
   <Employee>
      <Fname>Steve</Fname>
      <Lname>Mai</Lname>
   </Employee>   
Can be interpretd as this way:
   <Employee>
      <Element>
         <key>Fname</Key>
         <value>David</Value>
      </Element>
      <Element>
         <key>Lname</Key>
         <value>Miller</Value>
      </Element>
   </Employee>  
   <Employee>
      <Element>
         <key>Fname</Key>
         <value>Steve</Value>
      </Element>
      <Element>
         <key>Lname</Key>
         <value>Mai</Value>
      </Element>
   </Employee> 
Now you should understand what I mean.
In your case target structure have to desgined as following way:
You need to put Category and Property together with their sub-structure in parallel, make occurence to 0:1
In your second mapping, you can check the key value is "Type" or "Character", based on which one is true,
you create corresponding structure: either Categary or Property.
