I was doing some web scraping and i was looking for some div elements with particular class names and markup.

This is my objective , i have to extract everything within the div having the class s_specs_box s_box_4

Could someone please provide the regular expression in .NET terms (i.e., which can be straight away passed into Regex’s constructor)to match one such div (given below)

<div class=\"s_specs_box s_box_4\"><h3>Display</h3><ul><li><strong><span class='s_tooltip_anchor'>Display:</span>\n<span class='s_tooltip_content'><p class='s_help'><b>Display</b> - Phone's main display</p></span></strong><ul>\n<li class='clear clearfix'><strong><span class='s_tooltip_anchor'>Type:</span>\n<span class='s_tooltip_content'><p class='s_help'><b>Type</b> - Refers to the type of the display.

    You cannot parse HTML using regular expressions.

    Instead, you should use the HTML Agility Pack in C# or jQuery in Javascript.

    For example:

    var html = document.DocumentNode.Descendants("div")
    .First(div => div.GetAttributeValue("class", null) == "s_specs_box s_box_4")
    .InnerHtml;
