Remove Html Tags From String C# Top 20 Latest Posts

You can remove HTML tags from a string in C# by using Regular Expressions. Here’s an example code snippet that uses Regex to remove HTML tags from a string:

csharp
using System.Text.RegularExpressions;

string input = "<p>Example HTML string</p>";
string output = Regex.Replace(input, "<.*?>", string.Empty);

Console.WriteLine(output); // Output: Example HTML string

Explanation:

• The Regex.Replace method takes in the input string and replaces any matches of the pattern specified with the replacement string.
• The regular expression pattern "<.*?>" matches any HTML tag in the input string.
• The string.Empty parameter is used as the replacement string, effectively removing any matched HTML tags from the input string.
• The resulting output string is stored in the output variable and printed to the console.

In C#, you can remove HTML tags from a string by using regular expressions. Here’s an example code snippet that uses a regular expression to remove HTML tags:

vbnet
using System.Text.RegularExpressions;

public static string StripHTML(string input)
{
    return Regex.Replace(input, "<.*?>", String.Empty);
}

In this code, we first import the System.Text.RegularExpressions namespace, which contains the Regex class that we’ll use to perform the regular expression search and replace.

The StripHTML function takes a string input as its argument and returns a new string with all HTML tags removed. The regular expression <.*?> matches any HTML tag, including its attributes, and the String.Empty argument to Regex.Replace tells the function to replace the matched tags with nothing.

To use this function, simply call it with a string containing HTML tags:

scss
string htmlString = "<p>This is <b>bold</b> text.</p>";
string strippedString = StripHTML(htmlString);
Console.WriteLine(strippedString); // outputs "This is bold text."

In this example, the htmlString variable contains an HTML paragraph with some bold text. The StripHTML function is called with htmlString as its argument, and the resulting string, with all HTML tags removed, is stored in the strippedString variable. Finally, the Console.WriteLine function is called to output the stripped string to the console.

HtmlAgilityPack is a .NET library that allows developers to parse and manipulate HTML documents. It is commonly used in web scraping and screen scraping applications where the HTML of a web page needs to be processed programmatically.

HtmlAgilityPack provides a range of features for working with HTML documents, including:

1. Parsing HTML: The library can parse HTML documents and build a tree structure of the document’s elements and attributes. This tree structure can then be traversed to extract data or make modifications to the document.

2. XPath support: HtmlAgilityPack supports the use of XPath expressions to query and select specific elements from the HTML document.

3. Encoding detection: The library can detect the encoding of an HTML document, even if it is not specified in the document itself.

4. DOM manipulation: HtmlAgilityPack allows developers to manipulate the HTML document’s tree structure, including adding, removing, and modifying elements and attributes.

5. Output formatting: The library provides options for formatting the output HTML, including indentation and line breaks.

HtmlAgilityPack is available as a NuGet package and can be installed using the NuGet Package Manager in Visual Studio or the dotnet CLI.
