stripping tags from source on render

Hi,
What way could I strip certain tags (like HTML comments) from the HTML being
delivered to the client? I don't mean what regexp to use, but where do I
put this stripping code? I'm thinking something in the Global.asax, but I
can't find any reference to it having a Render or PreRender event or how to
tie into them if I did! I'd ideally like some help along the lines of:

1 - Where to put the code
2 - example of how to alter the source being delivered to the client

Thanks,
LanceHi Lance:

You could use a Response.Filter, like the one in this article:

Hi Lance,

I'd look at the Page.Render event. This takes an HtmlTextWriter parameter
where you can modify the contents before calling the base.Render method.

I'd have to call the code from every page using this method, right? If I
could call it from one location (global.asax) that would be great!

Stripping out unwanted characters

How can I strip out unwanted characters in a string before updating the
database? For instance, in names & addresses in our client table, we want
only letters and numbers, no punctuation. Is there a way to do this?HI,

Use regular expression to remove unwanted characters and then send the
string to database. Here is a sample code to remove non-alphanumerical
characters from a string.

hoep this will help you...

public static void Main()

{

/*Reg expression to find non-alphanumeric characters*/

string pattern = @."[^A-Za-z0-9]";

/*include System.Text.RegularExpressions name space*/

Regex rgx = new Regex(pattern);

string inputStr = "ab$!Cd&%$gf!";

/*Replace non-alphanumeric characters with space*/

string outputStr = rgx.Replace(inputStr, " ");

Console.WriteLine("Output string:"+ outputStr);

}

Cheers
Vinu

Function StripUnwantedChars(ByVal StringToStrip AsString) AsString
Dim stripped AsString
If StringToStrip <> "" Then
stripped = Regex.Replace(StringToStrip, "<(.|\n)+?>", String.Empty)
Return stripped
Else
Return ""
EndIf
EndFunction

Note : insert all the characters you want to strip inside the quotes.

For example, instead of :
stripped = Regex.Replace(StringToStrip, "<(.|\n)+?>", String.Empty)

use :
stripped = Regex.Replace(StringToStrip, "<!#(.|\n)+?>", String.Empty)

Thanks, everyone, that's exactly what I was looking for.
