SQL inserting data based on nested xpath - sql-server

Question

I have a simple insert statement that I am working on. This query inserts a core record, returns an ID, and then inserts a one or more tasks into another table. For each of those tasks, I need to do an additional insert into a 3rd table.
I am having a little trouble trying to figure out how to set this up due to the second insert statement happening before the 3rd, so I am not sure about how to get the identity from each insert to pass to query 3.
DECLARE #requestID INT;
-- Insert the core request details
INSERT INTO esas.Request (Requestor, Justification, CreatedBy, DateCreated)
SELECT #requestor,
#justification,
#creator,
GETUTCDATE()
-- Define the core request ID
SET #requestID = SCOPE_IDENTITY();
-- Add tasks
INSERT INTO esas.Task
( RequestID ,
ToolID ,
QID ,
Action
)
SELECT #requestID,
ParamValues.x1.value('tool[1]', 'INT'),
ParamValues.x1.value('user[1]', 'VARCHAR(10)'),
ParamValues.x1.value('action[1]', 'INT)')
FROM #tasks.nodes('/request/task') AS ParamValues(x1);
-- For each task, add any associated roles (stuck here)
INSERT INTO esas.TaskRoles
( TaskID,
RoleID,
ActionID )
VALUES ( 0, -- TaskID - int
0, -- RoleID - int
0 -- ActionID - int
)
In the last insert, I need to pass the PK/AI the TaskID created from "Add Tasks" to another table, along with the roleID and action from the XML string.
Here is my XML structure:
<request>
<task>
<tool>123</tool>
<user>4567</user>
<roles>
<role>
<roleID>12</roleID>
<action>1</action>
</role>
<role>
<roleID>1245</roleID>
<action>0</action>
</role>
<role>
<roleID>678</roleID>
<action>1</action>
</role>
</roles>
</task>
</request>
My confusion is due to knowing that INSERT INTO esas.Task is going to all happen at once before moving on so I am not sure how to pass each identity to the next insert along with its corresponding details in the XML structure.

I figured this out using xpath and joining the tasks table after the data had been inserted.
-- For each task, add any associated roles
INSERT INTO esas.TaskRoles
( TaskID,
RoleID,
ActionID )
SELECT t.TaskID,
ParamValues.x1.value('roleID[1]', 'INT'),
ParamValues.x1.value('action[1]', 'INT')
FROM esas.Task AS t
JOIN #tasks.nodes('/request/task/roles/role') AS ParamValues(x1)
ON t.RequestID = #requestID
AND t.ToolID = ParamValues.x1.value('../../tool[1]', 'INT')
AND t.QID = ParamValues.x1.value('../../user[1]', 'VARCHAR(10)')
