How to replace a html string?


When I read an upload html file from an email program and send to the recipient, I need to replace a html string insides it

<a href=""><img src="" border="0" valign="top"></a>

<a href="''"><img src="" border="0" valign="top"></a>

So that people can click the button to reply and confirm.

Here is the code:

public string SqlEncode(string inStr)
            inStr = inStr.Replace("<a href=""><img src="" border="0" valign="top"></a>", "<a href="'"><img src="" border="0" valign="top"></a>
            return inStr;

But, it does not work.

There are several img links like
img src=""
img src=""
img src=""

Or, I should add \ before all " ?

Please advise

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you want to do it that what then why not just do this:
inStr = inStr.Replace(@"<a href="""">", "<a href=\"\">");

You would be better off using a regex to take into account any variations etc.

because there are many
<a href="""">

it will replace all with the same url.
there is no id for each  <a href=""""> tag
Then you are better off using regular expression matching and running it against a dictionary using the URL as the key and the e-mail address as the value.  Could end up very messy though...
