Hi,
I'm looking the best way to manage multiple XMLTYPE concatenate.
An option is put the values on a temp table like this:

PROCEDURE enqueue_xml (v_xml IN OUT nocopy XMLTYPE)
IS
begin
insert into T_GENERIC_XML VALUES (v_xml);
END;

PROCEDURE get_queue_xml (v_xml OUT NOCOPY XMLTYPE)
IS
begin
select xmlagg(xml) into v_xml
from T_GENERIC_XML;
END;

Anybody knows a better method to avoid the XMLCONCAT function?

It is not clear what you have and what you want, and from you call the procedures and in order to do what and so on.

Post a working Test case: create table and insert statements along with the result you want with these data then we will work with your table and data.

Before, Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version with 4 decimals.

Regards
Michel
