Help needed in writing query

Question

Hi,
Could anyone help me in writing below query without syntax errors.
I tried but no luck
select xmlelement("g", XMLATTRIBUTES(g.contentgroup_id as "id",g.groupname as "label",
(select xmlagg(xmlelement ("c",XMLATTRIBUTES(c.title as "title",c.content_id as "id")))) as "A"))
as "A" from
(SELECT g.contentgroup_id AS id, g.groupname AS label, c.title AS label, c.content_id AS id
FROM content_ec c FULL OUTER JOIN contentgroup_ec g ON c.group_id = g.contentgroup_id
oRDER BY g.groupname ,c.title ASC );
Any help really appreciated.
Thanks

Few tips to get your question answered here
1. Give your database version. Some thing that does not work in one version works fine in the next. And 8i,9i or 10g is not version. best way to give the version is to query your v$version table like this.
SQL> select * from v$version where rownum = 1
  2  /
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod2. You should understand we don't have what you have, meaning you should provide your data structure and some sample data for us to help.
3. "I got an error"... "Its not working"... and the list goes on. Sentences like this does not help. If you got a error past the entire error. If stuff does not work, tell us the details.
4. Just don't throw some output and say i want it. Please explain to every one how you derive it.
5. And the most important thing. Use \...\ tag to format. Please.. Please.. Please.. use it. It helps every one a lot. When you use it your SQL looks some thing like this.
SELECT xmlelement("g", XMLATTRIBUTES(g.contentgroup_id as "id",g.groupname as "label",
     (select xmlagg(xmlelement ("c",XMLATTRIBUTES(c.title as "title",c.content_id as "id")))) as "A")) as "A"
   FROM (SELECT g.contentgroup_id AS id,
             g.groupname AS label,
             c.title AS label,
             c.content_id AS id
        FROM content_ec c
        FULL OUTER JOIN contentgroup_ec g
          ON c.group_id = g.contentgroup_id
       ORDER BY g.groupname ,c.title ASC );6. And also do search this forum. Most of your my queries are answered by simple search.
