HTML Tag Remover: Cleaning Up Web Content

What is HTML Tag Removal?

HTML tag removal is the process of stripping HTML markup from a text, leaving only the raw content. This is useful for extracting plain text from HTML documents, cleaning up user-generated content, or preparing text for further processing.

The Tag Removal Formula

The process of tag removal can be represented mathematically as:

\[C_f = C_i - \sum_{t=1}^{n} (L_{t_o} + L_{t_c})\]

Where:

• \(C_f\) is the final character count
• \(C_i\) is the initial character count
• \(n\) is the number of tags
• \(L_{t_o}\) is the length of the opening tag
• \(L_{t_c}\) is the length of the closing tag

Calculation Steps

1. Count the initial number of characters in the HTML string.
2. Identify all HTML tags in the string.
3. For each tag:
   • Measure the length of the opening tag
   • Measure the length of the closing tag (if present)
   • Sum these lengths
4. Subtract the total tag length from the initial character count.

Example

Let's consider the following HTML string:

<p>Hello <strong>world</strong>!</p>

Initial character count (\(C_i\)): 32

Tags present:

• <p> and </p>: 7 characters
• <strong> and </strong>: 17 characters

Total tag length: 24 characters

Final character count (\(C_f\)): 32 - 24 = 8

Resulting text: "Hello world!"
