For example:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>title</title>
</head>
<body>
<a href="aaa.asp?id=1"> I want to get this text </a>
<div>
<h1>this is my want!!</h1>
<b>this is my want!!!</b>
</div>
</body>
</html>
and the result is:
I want to get this text
this is my want!!
this is my want!!!
Change to
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>title</title>
<head>
<body>
<a href="aaa.asp?id=1" runat="server" id="mya"> I want to get this text <a>
<div>
<h1 runat="server" id="myh1">this is my want!!<h1>
<b runat="server" id="myb">this is my want!!!<b>
<div>
</body>
</html>
At code-behind, use mya.InnerHtml, myh1.InnerHtml, myb.InnerHtml
I would recommend using something like HTMLTidy.
Here's a tutorial on it to get you started.
Why do you want to make it server side?
For that you have to make the container element runat="server" and then take the innerText of the element.
You can do the same in javascript without making the element runat="server"
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
string s = doc.DocumentNode.SelectSingleNode("//body").InnerText;
If you just want to remove the html tags then use a regular expression that deletes anything between "<" and ">".
Use this function...
public string Strip(string text)
{
return Regex.Replace(text, @”<(.|\n)*?>”, string.Empty);
}
Use this function:
public static string RemoveTags(string html)
{
string returnStr = "";
bool insideTag = false;
for (int i = 0; i < html.Length; ++i)
{
char c = html[i];
if (c == '<')
insideTag = true;
if (!insideTag)
returnStr += c;
if (c == '>')
insideTag = false;
}
return returnStr;
}
