XML Forest,XML Concat

Hi,

I have a wo function in oracle which returns XML type.

Sample XML From First Function
<customer>
<Fname>testFname</Fname>
<Lname>testLname</Lname>
</customer>

Sample XML From Second Function
<PostalAddress>
<address1>testaddress1</Fname>
<address2>testaddress2</Lname>
</PostalAddress>

I need to add postal address tag under customer tag.

Oupt Put

<Customers>
<customer>
<Fname>testFname</Fname>
<Lname>testLname</Lname>
<PostalAddress>
<address1>testaddress1</Fname>
<address2>testaddress2</Lname>
</PostalAddress>
</customer>
</Customers>

how to achieve this ?

Regards,
Chandan N

you don't want to use xmelement or any of the xml aggregation functions,
you are simply inserting nodes within other nodes.

use INSERTCHILDXML to do that...


select INSERTCHILDXML(
           xmltype('<Customers></Customers>'),
           '/Customers',
           'customer',
           INSERTCHILDXML(function1, '/customer', 'PostalAddress', function2)
       ) from dual

The core part is to get the nodes;sdstuber solution didnt had that part correct.That is the main element of the solution.How can this comment be considered as a correct one if it is not working,I had to do lot of work around to get the solution,Only the syntax is correct,But the logic is not correct,
Before accepcting the solution forcibly,The solution has to be checked for its logic.
Please refund my points back.

Chandan_Gowda,

Sorry, I was gone on vacation for several days and just got back to see the comments.

I didn't have the your functions to work with so I wrote my own that returned the xml presented in the original question (except I corrected the address1 and address2 closing tags)
The post I made above is exactly what I tested with and it returned exactly the xml you requested.

The query I posted returns the requested xml, if this does not work, please post what did not work about it.
I've attached the functions from my test case.

<Customers>
  <customer>
    <Fname>testFname</Fname>
    <Lname>testLname</Lname>
    <PostalAddress>
      <address1>testaddress1</address1>
      <address2>testaddress2</address2>
    </PostalAddress>
  </customer>
</Customers>

 
create or replace function function1 return xmltype
is
begin
  return xmltype('<customer>
<Fname>testFname</Fname>
<Lname>testLname</Lname>
</customer>');
end;
 
--  Note, address1 and address2  closing tags have been corrected, from the original question's sample data.
create or replace function function2 return xmltype
is
begin
  return xmltype('<PostalAddress>
<address1>testaddress1</address1>    
<address2>testaddress2</address2>
</PostalAddress>');
end;
