I have a ntext field in my report and it has a lot of tags which made it non-readable. I want to replace those tags. I used replace in expression for that field, but how to replace some tags with new lines.

For eg, the field looks like this:
<DIV><B>Edited on Monday, November 12, 2007 at 10:58 AM</B><BR>We discussed this issue and continue working on it.<BR><BR>

but actually in the program interface it looks like this:

We discussed this issue and continue working on it.

so I want the same to be shown up on the report. I can replace those tags with empty space but I can't make a new line. Is there a work-around? Thanks a lot!

You can do a replace with either a CHAR(13) for a carriage return, or CHAR(10) for a new line feed:

SELECT REPLACE('Test<br>test','<br>', '' + CHAR(13) + '')

It will depend on the environment you are displaying the data in on how/if it will show the two lines or not. For example, the above SELECT statement doesn't really show two lines, but you can do the following to see it:

DECLARE @strPrint VARCHAR(100);
SELECT @strPrint=REPLACE('Test<br>test','<br>', '' + CHAR(13) + '')
PRINT @strPrint

The problem is that I can't use "replace" on field whose datatype is ntext, so I had to use "replace" in expression in Reporting Services but I got error  ('CHAR' is a type and cannot be used as an expression.) when I was trying to preview the report.
= replace(Fields!ID_Features_Description.Value,"<BR>", ""+CHAR(13)+"")

for SQL 2000
from http://sqlserver2000.databases.aspfaq.com/how-do-i-handle-replace-within-an-ntext-column-in-sql-server.html

for SQL 2005
just use
update table set field = replace(cast (field as nvarchar(max)), '<br>', Char(13) + Char(10))

In reporting services you should be able to use vbNewLine:

="Line One" & vbNewLine & "Line Two"

Thanks for the help! I tried before to convert the ntext to varchar and it didn't work now I know nvarchar(max) works. Thanks again!
