Hi All, I have a field coming from database, it is a html code. sample: "html tag"extract content from html code at code behind"/html tag""html tag"did have solution?"/html tag" At code behind I need to count the text, such like "extract content from html code at code behind" + "did have solution?". if the length exceeds the limit, do something. How can I get the real text without HTML tag in my cs file? Thank you in advance.

            foreach (Match m in mc)
            {
               HTML = HTML.Replace(m.ToString(),"");

            }
            MessageBox.Show(HTML);
            MessageBox.Show(HTML.Length.ToString());

            //Do the operation you want to do with Length

thank you for all your reponse. Really appreciate your time.

Finally I decided to make changes on my trigger, to get those string length take cared before inserting to table. Thank you again.

your code will remove all the data between < and > tag for example <a href=" temp_href"> Our Blog >;

because the first and the last symbols are < and > contains the whole if look deeply...

try to use FirstIndexOf() and LastIndexOf() method to get the result right.

Thank you, Roei Bar and Kirtan, for your help. I read a string from db, str has HTML code in it. I want to count the text length only in string withought counting any HTML tag. Wish I explained clearly. thank you again for your time.

btw, Regex.Replace(feed.Content, "<(.|\n)+?>"," "); let me get the result.

here is an example: (you may not see the html tags because browser renders it)

Linda Smith commented on AMERICAN HEART ASSOCIATION INC

Now I have the text of "Linda Smith commented on AMERICAN HEART ASSOCIATION INC" by using regex.replace; since the string length exceeds the limit, I used substring to cut, and display "Linda Smith commented on AMERICAN HEART ASSOC..." on UI.

However, I have the right length of string, the link is gone. It should have 2 links.

here is my part of code:

string strContent;

strContent = Regex.Replace(feed.Content, "<(.|\n)+?>"," ");

if (strContent.Length > 50)
{
ltContent.Text = String.Format(CultureInfo.InvariantCulture, "{0}...", strContent.Substring(1, 49));
}
else
{
ltConten = feed.content;
}

How cau I keep the link and cut the length?

you can either run an XSLT transform and look fo rthe text

or you could use a regex
