BBCode to HTML

What is BBCode and how does it differ from HTML?

BBCode (Bulletin Board Code) is a lightweight markup language used to format posts in many message boards. It is designed to be simpler than HTML and less prone to user errors. BBCode uses square brackets [] instead of angle brackets <> used in HTML. For example, [b]bold text[/b] in BBCode is equivalent to <b>bold text</b> in HTML.

How do you convert BBCode tags to HTML tags?

Converting BBCode to HTML involves mapping BBCode tags to their corresponding HTML tags. Here are a few examples:

• [b]bold text[/b] converts to <b>bold text</b>
• [i]italic text[/i] converts to <i>italic text</i>
• [u]underlined text[/u] converts to <u>underlined text</u>
• [url=http://example.com]Example[/url] converts to <a href="http://example.com">Example</a>

Are there any tools or libraries available to convert BBCode to HTML automatically?

What are some common challenges when converting BBCode to HTML?

Some common challenges include:

• Nested Tags: BBCode allows nesting of tags, and correctly converting them to HTML requires maintaining the correct order and structure.
• Custom Tags: Many forums support custom BBCode tags which may not have a direct HTML equivalent, requiring custom handling during conversion.
• Security: Ensuring that the conversion process does not introduce vulnerabilities such as XSS (Cross-Site Scripting) by sanitizing the input properly.

Can BBCode handle all the functionalities of HTML?

No, BBCode is more limited compared to HTML. BBCode is designed primarily for simple text formatting and embedding links, images, and videos. It does not support complex layouts, styles, or scripts like HTML does. BBCode is intentionally limited to prevent users from breaking the layout or introducing security issues on forums.
