TSQL Removing HTML tags from a field
Hello Experts,
I'm not sure if this is possible but i'm trying to read a text field into a temporary table and get rid of all html tags in it.
select substring(descriprion,1,20
I want to get rid of html tags that might exist in that column. the problem is I can not simply use Replace() and have it hardcoded since it may contain different HTML (e.g. <font color=red size=20> my description </font>)
I'm pretty much lookin for suggestions to achieve this
Thanks in advance

i would rather do it myself in vb.net but that's what i was asked to do.
Thanks g_johnson, didn't know those functions exist! (CHARINDEX and PATINDEX)
Here's the code if somebody's interested. it's a dumb code but enough for my purposes
CREATE FUNCTION dbo.removeHTMLTag
(
@myStr VARCHAR(2000) =''
)
RETURNS varchar(2000)
AS
BEGIN
DECLARE @result VARCHAR(2000)
DECLARE @index INT
DECLARE @leftPos INT
DECLARE @rightPos INT
DECLARE @toBeRemovedStr VARCHAR(2000)
SET @index = patindex('%<[A-Z,/]%>%', @myStr)
WHILE (@index <> 0)
BEGIN
set @leftPos = @index
set @rightPos = charindex('>',subString(@m
set @toBeRemovedStr = substring(@myStr,@leftPos,
set @myStr = replace(@myStr,@toBeRemove
SET @index = patindex('%<[A-Z,/]%>%', @myStr)
END
select @result = @myStr
return ltrim(rtrim(@result))
END

glad I could help
TSQL is not really the best idea to do this job, I would rather use some other programming/scripting language, using the MSXML documents objects to get rid of the html tags...
