Read XML file into SQL Server database

Question

I'm trying to read an XML file into a database table that already exists.

The problem is that the XML tags and the database columns don't have the same name although they have the same datatype. Therefore I'd like to "translate" the XML tags into the database columns so that the the input to the database becomes possible.

I'm not sure how to do that however.

Here is what I've done so far.

static void writeToDatabase()
{
    XmlDocument doc= new XmlDocument();

    try {
        // Reading the xml
        doc.Load("C:\\Temp\navetout.xml");

        DataTable dt = new DataTable();

        // Code here to read the xml into an already existing database table?
    } 
    catch (Exception e) 
    {
        Console.WriteLine(e.Message);
    }
}

The database is located on another server, I've included this in the app.config

<connectionStrings>
    <add name="CS"
         connectionString="Data Source=tsrv2062;Initial Catalog=BUMS;Integrated Security=True"/>
 </connectionStrings>

Let's say for an example that the XML file has the tags "Name" while the database table column has the column "Firstname".

XML example:

<?xml version="1.0" encoding="utf-8"?>

Here for an example, the <PersonNr> tagg and the databse column PersonalIdentityNumber are the same. The column that doesn't match with the XML-tags are supposed to returning null.

Before reading the the XML data into the database table, I suppose the XML-tags has to be translated into the Database table column. In this case "Firstname".

Can anyone help me out with this "translation" and the reading into the database table.

DECLARE @xml XML
SELECT @xml = BulkColumn
FROM OPENROWSET(BULK 'D:\sample.xml', SINGLE_BLOB) x

SELECT
    t.c.value('(PersonId/PersonNr/text())[1]', 'VARCHAR(100)'),
    t.c.value('(Namn/Tilltalsnamnsmarkering/text())[1]', 'INT')
FROM @xml.nodes('*:ArrayOfFolkbokforingspostTYPE/*:FolkbokforingspostTYPE/*:Personpost') t(c)
