This is an ideal candidate for the use of a SQL MERGE. It allows you to insert/update/delete based on matching criteria in a single statement.

Check the Microsoft Technet reference for further information.

Edit: Here's some example code for using SQL MERGE alongside OPENXML

declare @idoc int;
declare @inputXml xml = N'
<data>
    <item>
        <id>1</id>
        <name>first</name>
    </item>
    <item>
        <id>2</id>
        <name>second</name>
    </item>
    <item>
        <id>5</id>
        <name>fifth</name>
    </item>
</data>';
-- idoc is the xml representation we work with
EXEC sp_xml_preparedocument @idoc OUTPUT, @inputXml;


-- setup our table to merge
DECLARE @myTable TABLE (id int primary key, name varchar(50))
INSERT INTO @myTable (id, name)
VALUES 
    (1, 'one'),
    (2, 'two'),
    (3, 'three');

SELECT * FROM @myTable

-- merge the selected XML content into myTable
-- if we match on ID, update the name
-- if we don't find a match in the table, insert the entry in the XML
-- if we don't find a match in the XML, delete the entry in the table

MERGE INTO @myTable AS Target
USING 
    OPENXML(@idoc, 'data/item', 2) 
    WITH (id int 'id/text()', name nvarchar(50) 'name/text()')
    AS source
ON Target.id = source.id
WHEN MATCHED THEN UPDATE SET name = source.name
WHEN NOT MATCHED BY TARGET THEN INSERT (id, name) VALUES (id, name)
WHEN NOT MATCHED BY SOURCE THEN DELETE;

SELECT * FROM @myTable
