How to insert into xml table from relational table

Question

I wrote a sqlstaement that selects value from the relational tables. Now I want to replace root node "<event_start01>" with following value to the above selected xml string. My select returns root node and all nodes and elements of the root node.
I tried holding above sellected value into varchar2 variable but I get ora-00600 error. If I hold above selected values into xmltype variable then I am not able to replace root node with the following value.
I want to rplace rootnode with the following string.
INSERT INTO FRMD_EVENT_START01(xml_event_start) VALUES
(XMLTYPE('<event_start01
xmlns="event_start01.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="event_start01.xsd
event_start01.xsd">

Normally, you'd do this by joining B, C, and D together. In the simplest case, something like
INSERT INTO A( col1, ... col10 )
  SELECT B.col1, ..., B.col4,
         C.col5,
         D.col6, ..., D.col10
    FROM B,
         C,
         D,
   WHERE B.someKeyColumn = C.someKeyColumn
     AND C.anotherKeyColumn = D.anotherKeyColumnYou'd have to know how the data in B, C, and D relate to fill in the WHERE clause. This basically tells Oracle how to match the data in a particular row in B with the data in a particular row in C with the data in a particular row in D.
