In this post, I have created one user defined function to remove all HTML tags from the string data of SQL Server.

There are certain requirements like, store HTML document into the text column, but unfortunately it also contains HTML tags which required to remove.

I have found one user defined function to remove all HTML Tags from the given string.

CREATE FUNCTION dbo.RemoveHTML (@HTMLData VARCHAR(MAX)) 
RETURNS VARCHAR(MAX) AS
BEGIN
    DECLARE @HTMLDataXML XML
    DECLARE @ResultData VARCHAR(MAX)
    SET @HTMLDataXML = REPLACE( @HTMLData, '&', '' );
    WITH HTMLDoc(texts) AS
    (
        SELECT chunks.chunk.query('.') FROM @HTMLDataXML.nodes('/') AS chunks(chunk)
    )
    SELECT @ResultData = texts.value('.', 'varchar(max)') FROM HTMLDoc
    RETURN @ResultData
END
GO

Sample Execution:

SELECT dbo.RemoveHTML('<html><body> This <i> is </i> a <b>Database</b> Research and <u>Development </u> </body></html>')

CREATE FUNCTION fn_RemoveHTMLTag (HtmlString text) RETURNS text
