import dynamic xml to sql server - sql-server

Question

This sample XML shown here is what I want to import into a SQL Server table. The XML tags are dynamic here.( xml element name differ in othe xml files. Also number of xml elements in root and child nodes are different for each xml file)
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:heal="http://healthedge.com">
<soapenv:Header/>
<soapenv:Body>
<heal:getClaimDetailsByHccID>
<claimHccNumber>10</claimHccNumber>
<claimDetailFlags>
<includeAccounts>a</includeAccounts>
<includeAccumulators>b</includeAccumulators>
</claimDetailFlags>
<claimFilterParameters>
<includeTransientStates>true</includeTransientStates>
<mostRecentPaymentOnly>false</mostRecentPaymentOnly>
</claimFilterParameters>
</heal:getClaimDetailsByHccID>
</soapenv:Body>
</soapenv:Envelope>
I want to store xml into 3 different tables, one table for each level element(root,child, sub child) the tag names are stored as row data.
Output should look like this:
Parent table
id value
---------------------------
1 getClaimDetailsByHccID
Root table
parent_id root id name value
------------------------------------------------------
1 1 claimHccNumber 10
1 2 claimDetailFlags null
1 3 claimFilterParameters null
Child table
root id child id name value
--------------------------------------------------------
2 1 includeAccounts a
2 2 includeAccumulators b
3 3 includeTransientStates TRUE
3 4 mostRecentPaymentOnly FALSE
i tried using below code, here value is not populating correctly for rootTable code:-
DROP TABLE IF EXISTS ChildTbl;
DROP TABLE IF EXISTS RootTbl;
DROP TABLE IF EXISTS ParentTbl;
CREATE TABLE ParentTbl (ID INT IDENTITY PRIMARY KEY, [value] VARCHAR(100));
CREATE TABLE RootTbl (root_id INT IDENTITY PRIMARY KEY, parent_id INT, [name] VARCHAR(100), [value] VARCHAR(100));
CREATE TABLE ChildTbl (child_id INT IDENTITY PRIMARY KEY, parent_id INT, [name] VARCHAR(100), [value] VARCHAR(100));

Answer 1

It is not so clear what it means "...The XML tags are dynamic here...".
Please try the following solution.
USE tempdb;
GO
-- DDL and sample data population, start
DROP TABLE IF EXISTS dbo.ChildTbl;
DROP TABLE IF EXISTS dbo.RootTbl;
DROP TABLE IF EXISTS dbo.ParentTbl;
CREATE TABLE dbo.ParentTbl (ID INT IDENTITY PRIMARY KEY, [value] VARCHAR(100));
CREATE TABLE dbo.RootTbl (root_id INT IDENTITY PRIMARY KEY
, parent_id INT NOT NULL FOREIGN KEY REFERENCES dbo.ParentTbl(ID), [name] VARCHAR(100), [value] VARCHAR(100));
CREATE TABLE dbo.ChildTbl (child_id INT IDENTITY PRIMARY KEY
, parent_id INT NOT NULL FOREIGN KEY REFERENCES dbo.RootTbl(root_id), [name] VARCHAR(100), [value] VARCHAR(100));
