What is XHTML?

What is XHTML?
Answer1:
XHTML is a more formal, stricter version of HTML. XHTML is defined by an XML dtd which makes it much easier to handle.

Answer2:
* XHTML stands for eXtensible Hyper Text Markup Language.
* It is aimed to replace HTML.
* It is almost identical to HTML 4.01
* It is the reformulation of HTML 4.01 as an application of XML.
* It is a stricter, tidier version of HTML.
XHTML 1.0 is the next level of coding as specified by the W3C.
XHTML is a transition / combination of HTML and XML. To change from HTML to XHTML requires just a few changes in your coding styles. The main page to check out is CONVERTING but all the others provide valuable information about this coding technique as well.
XHTML provides the framework for future extensions of HTML and aims to replace HTML in the future. Some resources refer to XHTML as HTML5.
XHTML 1.0 became an official W3C recommendation on January 26, 2000. A W3C recommendation means that the specification is stable, that it has been reviewed by the W3C membership, and that the specification is now a Web standard.
XHTML 1.0 is the first step toward a modular and extensible web environment based on XML (eXtensible Markup Language). It provides the bridge for web designers to use a future based coding and still be able to maintain compatibility with today's browsers.
XHTML is a stricter and cleaner version of HTML.

XHTML is a combination of HTML and XML (EXtensible Markup Language).
XHTML consists of all the elements in HTML 4.01 combined with the syntax of XML.
Advantages of using XHTML instead of HTML
1. Documents can be validated much easier
2. Documents can be transformed via tools like XSLT into other documents for consumption by devices like handhelds
3. Fragments of documents can be retrieved faster
4. Text can be stored more effieciently in object oriented databases


Answer4:
The great thing about XHTML, though, is that it is almost the same as HTML, although it is much more important that you create your code correctly. You cannot make badly formed code to be XHTML compatible. Unlike with HTML (where simple errors (like missing out a closing tag) are ignored by the browser), XHTML code must be exactly how it is specified to be. This is due to the fact that browsers in handheld devices etc. don't have the power to show badly formatted pages so XHTML makes sure that the code is correct so that it can be used on any type of browser.

Answer5:
XHTML combines XML and HTML 4 to provide developers with a language that conforms to the XML format, as opposed to HTML which is based on SGML. XML is much simpler to parse than SGML, and standards exist such as XSLT, XPath, and XQuery for manipulating XML documents. Unfortunately, support for XHTML in browsers is poor, with the leading browser, Microsoft Internet Explorer, not supporting the XHTML mime type 'application/xhtml+xml'.
