How to extract specific part of html page using c# code -

-

I have a webpage that I want to remove a specific part of the page but not the full page, for example, 4 inches From the left side, just above 4 inches, above the website page. Please guide me how to get it. Here's my code. 

  public string GetWebSiteContents (string url) {WebRequest req = WebRequest.Create (url); // Get Stream from the Web's response back to StreamReader sr = New StreamReader (req.GetResponse (). GetResponseStream ()); System.Text.StringBuilder sb = New System Text.StringBuilder (); String stroke; // Read the line one line at a time and keep each one in stringbuilder while ((strLine = sr.ReadLine ()) = = null {// Ignore empty rows if (strLine.Length> gt; 0) sb .Append (strLine); } Sr.Close (); Textbox1.Text = sb.ToString (); Return sb.ToString (); }

This code works fine, but removes the full page and takes a long time in it.

An easy way to get what you are trying to do is to use a tool like selenium To automate an actual browser to use and then using HTML tags, you can save any information, for example the left-hand side of the page or table. See for a tutorial on Selenium.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
