OR, Close your <script> and <canvas> tags!. The relationships among HTML, XML and XHTML are an area of considerable confusion on the web. We often see questions on the webkit-dev mailing list where people wonder why their seemingly XHTML documents result in HTML output. Or we're asked why an XML construct like <b /> doesn't actually close the bold tag The W3C intended XHTML 1.0 to be identical to HTML 4.01 except where limitations of XML over the more complex SGML require workarounds. Because XHTML and HTML are closely related, they are sometimes documented in parallel. In such circumstances, some authors conflate the two names as (X)HTML or X(HTML). Like HTML 4.01, XHTML 1.0 has three sub. Overview. XHTML 1.0 is a reformulation of the three HTML 4 document types as applications of XML 1.0. The World Wide Web Consortium (W3C) also continues to maintain the HTML 4.01 Recommendation, and the specifications for HTML5 and XHTML5 are being actively developed. In the current XHTML 1.0 Recommendation document, as published and revised to August 2002, the W3C commented that, The XHTML.

XHTML is predominantly identical to HTML4 which was the fourth edition of HTML. The one difference between the two was that XHTML came with elements of XML that extended HTML's capabilities. HTML5 is a hybrid of three types of code and these are HTML, CSS, and JavaScript In HTML, we have empty elements that do not require closing tags. In XHTML, they need to be closed as well. While they do not have any content, they need to close themselves by containing a forward slash.In the example above, you could see the <br> tag. In XHTML, it would be written as <br />.. There are also elements that XHTML does not allow you to skip XHTML is almost identical to HTML 4.01 with only few differences. This is a cleaner and stricter version of HTML 4.01. If you already know HTML, then you need to give little attention to learn this latest version of HTML. XHTML was developed by World Wide Web Consortium (W3C) to help web developers make the transition from HTML to XML HTML Versus XHTML WaSP asks. Which should we use, HTML or XHTML, and why? The W3C Responds First, a bit of history. The history of HTML at W3C starts with HTML 3.2, code named Wilbur, which was followed a few years later by HTML 4.0, then HTML 4.01.HTML 4.01 is the last version of HTML, and is also the final W3C specification to define the semantics of markup

HTML-to-XML Importer. Visually develop rich XSLT stylesheets for XML-data driven websites, quickly and intuitively, starting from existing HTML pages - convert mal-formed HTML to XHTML, validate XHTML and publish in minutes XHTML stands for eXtensible HyperText Markup Language and is HTML written in an XML dialect.This is an advantage because programs for parsing XML are common and relatively simple, compared to HTML parsers which must be highly complex to interpret the loose syntax of HTML The topics of HTML vs. XHTML and XHTML as text/html vs. XHTML as XHTML are quite complex. Unfortunately it's hard to get a complete picture, since information is spread mostly in bits and pieces around the web or is buried deep in W3C tech jargon

  6. After XHTML 1.0, the W3C's focus turned to making it easier for other working groups to extend XHTML, under the banner of XHTML Modularization. In parallel with this, the W3C also worked on a new language that was not compatible with the earlier HTML and XHTML languages, calling it XHTML2

As XHTML looks so much like classic HTML, it faces no compatibility problems as long as some simple coding guidelines are followed. If all of this sounds a bit heavy, don't worry.

  2. After HTML 4.01 and XHTML 1.0, the guys who were in control of HTML's direction got sidetracked working on a new proposal for XHTML 2. At the same time, clever web developers were innovating constantly, hacking new functionality into websites and browsers
  3. The major difference between HTML and XHTML is that HTML is based on SGML which stands for Standard Generalized Markup Language. SGML is a standard according to which a document markup language or tag set is specified. This type of specifications.
  4. In both HTML and XHTML, within each tag, whitespace is permitted after the tag name, but it is not permitted before the tag name. Some authors choose to include a space before the slash in the self-closing tag. This practice.

Namespaces prevent identically custom-named tags that may be used in different XML documents from being read the same way), which correspond to three HTML 4.0 DTDs: Strict, Transitional, and Frameset The differences Between HTML and XHTML.
