Getting value from string using specific conditions

I have an html data in my string in which i need to get only paragraph values.Below is a sample html.

<html>
  <head>
    <title>
       <script>
          <div>
               Some contents
           </div>
          <div>
            <p> This is what i want </p>
            <p> Select all data from p </p>
            <p> Upto this is required </p>
          </div>
         <div>
          Other html elements
         </div>

So how to get the data from the paragraphs using string manipulation.

Desired Output

<Div>
  <p> This is what i want    </p>
  <p> Select all data from p </p>
  <p> Upto this is required  </p>
</div>

If you use Html Agility Pack as mentioned in the other posts, you can get all paragraph elements in the html by using:

HtmlDocument doc = new HtmlDocument();
doc.Load("your html string");
var pNodes = doc.DocumentNode.SelectNodes("//div[@id='id of the div']/p")

Since you are using .net Framework 2.0, you would want an older version of Agility Pack, which can be found here: HTML Agility Pack

If you want just the text inside the paragraph, you can use

var pNodes = doc.DocumentNode.SelectNodes("//div[@id='id of the div']/p/text()")

Xpath is the obvious answer (if the HTML is decent, has a root etc), failing that some third party widget like chilkat

I have used Html agility Pack for something like this. Then you can use LINQ to get what you want.

Give the div an ID, e.g.

<div id="test">
<p> This is what i want </p>
<p> Select all data from p </p>
<p> Upto this is required </p>
</div>

then use //div[@id='test']/p.

The solution broken down:

//div                    - All div elements
[@id='test']   - With an ID attribute whose value is test
/p
