VB.NET - Find and Replace in HTML Text

Hello,

I have HTML Text along with HTML tags.I want to find a particular word and replace it with other

Problem is if HTML Text contains text as "Cold,<strong>Cough</strong>,Fever,Para"

 And if i want to remove "Cough," then comma(,) is after strong closing tag (</strong>).

As in above case i have made Cough bold, user can do any HTML formatting so how can I remove particular 

word with comma.

whats problem if u wna to replace any word with comma(,)

string strippedText = System.Text.RegularExpressions.Regex.Replace("Cough",",");

rest format will be same where user done

If I understand your requirement correctly and based on your example, you want to highlight certain words in your HTML page.  This is similar to what other web pages do when they are found from a search engine like google.  If this is the case, the following links may be able to help you do just that:

Hello,

I have HTML Editor in my Windows application in which user can type and fomat their text such as they can make their text bold,Change Font,Text Color etc.I also have a grid in which User can select from the grid.

Whenever User selects record from the grid,the text from grid is added in my HTML Editor appending text with comma. i.e if User selects Cough and Cold from grid the text displayed in HTML Editor is

Cough,Cold.

Now after adding this text user can do various formatting as described above.

If the User makes "Cough" word BOLD then I have value as <strong>Cough</strong>,Cold.

Now if User deselects the cough row from grid it should be removed from HTMLEditor So now how can I find "Cough," so that the string remaining in HTML Editor is only "Cold" and not ",Cold"

and in my database I have stored text along with HTML tags.

One option you can do is to continue with your replacing of the string without the comma.  Then follow that replace with another replace and check if the remaining string starts with a comma and if it does, then remove that extra comma.  If the text that was replaced is in the middle of the selection, then look for two consecutive commas and replace it with a single comma.

So for case #1, "<strong>Cough</strong>,Cold" becomes ",Cold".  Since it starts with a comma, replace that first comma with an empty string.

And for case #2, "Flu,<strong>Cough</strong>,Cold" becomes "Flu,,Cold".  Since there's 2 commas together, replace that with a single-comma.

Hope this helps.

Case 2nd which you have told will not contain string as "Flu,,Cold" but the bold tag which was formatted for "Fever" will also be present in that string i.e the string will be "Flu,<stromg></strong>,Cold.

So how to parser and write generic code for a string which contains textalong with tags an d replace it?
