HTML vs XHTML
| HTML | XHTML |
|---|
| HTML stands for Hypertext Markup Language | XHTML stands for Extensible Hypertext Markup Language |
| It is an SGML application | It is an XML application |
| Tim Berners-Lee proposed it in 1987 | The World Wide Web Consortium recommended it in 2000 |
| HTML is not case sensitive | XHTML is case sensitive |
the xmlns attribute specifies the xml namespace for a document. This basically helps to avoid namespace conflicts between different xml documents, if for instance a developer mixes xml documents from different xml applications.
XHTML stands for
EXtensible HyperText Markup Language. It is the next step to evolution of internet. The XHTML was developed by World Wide Web Consortium (W3C). It helps web developers to make the transition from HTML to XML.
Difference Between HTML and XHTML:
| HTML | XHTML |
|---|
| Extended from SGML. | Extended from XML, HTML |
An XHTML document must have an XHTML DOCTYPE declaration. A complete list of all the XHTML Doctypes is found in our HTML Tags Reference. The <html>, <head>, <title>, and <body> elements must also be present, and the xmlns attribute in <html>, must specify the xml namespace for the document.
HTML is being defined in terms of the DOM and during parsing of a text/html all HTML elements will be automatically put in the HTML namespace, . However, unlike the XHTML serialization, there is no real namespace syntax available in the HTML serialization (see previous question).
SVG stands for Scalable Vector Graphics. SVG is used to define graphics for the Web. SVG is a W3C recommendation.
XHTML is not dead. As an XML format, it's, like SVG, as alive as XML is. In fact, HTML5 has an XML syntax (XHTML5), which is simpler and less confusing than the HTML4 syntax.

It's rarely called XHTML5 nowadays (and probably even more seldom used), since it's basically still HTML5, but it's still there. Simply put: every change to HTML5 spec is also an implicit, corresponding change to XHTML5. HTML5 is a de facto and de jure standard! XHTML is there, as standard also.
XML: XML (eXtensible Markup Language) is also used to create web pages and web applications. It is
dynamic because it is used to transport the data not for displaying the data.
HTML vs XML.
| HTML | XML |
|---|
| HTML stands for Hyper Text Markup Language. | XML stands for extensible Markup Language. |
| HTML is static. | XML is dynamic. |
HTML's full form is Hypertext Markup Language, while
XML is an Extensible Markup Language. The purpose of HTML is to display data and focus on how the data looks.
HTML vs XML: Key Differences.
| HTML | XML |
|---|
| Is a markup language. | Is a standard markup language that defines other markup languages. |
HTML stands for
Hyper Text Markup Language. It is used to design web pages using a markup language. HTML is the combination of Hypertext and Markup language. Hypertext defines the link between the web pages.
Difference between HTML and HTML5.
| HTML | HTML5 |
|---|
| Older version of HTML are less mobile-friendly. | HTML5 language is more mobile-friendly. |
XHTML5! Just when you thought XHTML may disappear, I have to tell you that XHTML has been evolved to accomodate the HTML 5 specification. You can write (only if you really want, of course) HTML 5 as valid XML.

5 advantages of XHTML over HTML
- Advantages.
- Sustainability. As web applications get increasingly sophisticated and move towards XML the use of XHTML will be more widespread.
- Wide range of applications.
- Compatibility.
- Efficient processing applications.
- Closing tags.
- Disadvantages.
- Limited practical use.
XHTML is a markup programming language that is similar to HTML but written using XML. Essentially, by using XHTML, you are writing XML code with restrictions based on a set of predetermined elements.
How to convert HTML pages into PDF files:
- On a Windows computer, open an HTML web page in Internet Explorer, Google Chrome, or Firefox.
- Click the “Convert to PDF” button in the Adobe PDF toolbar to start the PDF conversion.
- Enter a file name and save your new PDF file in a desired location.
Features of XHTML: Unlike HTML, which is standard generalized markup language based, XHTML is XML-based. Compared to the rules of HTML, XHTML is stricter and does not allow any lapses in coding or structure.

there are three main sections of XHTML consist of A declaration statement, a Head statement and a body.
XML is primarily made up of rules that govern tag syntax and is often used as a template for other markup languages. XHTML is a combination of the syntax rules from XML and the tags of the earlier HyperText Markup Language (HTML) used to create web documents.
No. XML itself does not replace HTML: instead, it provides an alternative which allows you to define your own set of markup elements. HTML is expected to remain in common use for some time to come, and a Document Type Definition for HTML is available in XML syntax as well as in original SGML.
Generally, HTML is case-insensitive, but there are a few exceptions. Entity names (the things that follow ampersands) are case-senstive, but many browsers will accept many of them entirely in uppercase or entirely in lowercase; a few must be cased in particular ways.
HTML is SGML-based while XHTML is XML-based. They are like two sides of the same coin. XHTML was derived from HTML to conform to XML standards. Hence XHTML is strict when compared to HTML and does not allow user to get away with lapses in coding and structure.
The HTML document type declaration, also known as DOCTYPE , is the first line of code required in every HTML or XHTML document. The DOCTYPE declaration is an instruction to the web browser about what version of HTML the page is written in. This ensures that the web page is parsed the same way by different web browsers.

HTML 4.01 / XHTML 1.0 Tags Reference
| Tag | Description |
|---|
| <i> | Specifies italic text |
| <iframe> | Specifies an inline sub window (frame) |
| <ilayer> | Specifies an inline layer |
| <img> | Specifies an image |
To convert XHTML to HTML , drag and drop your XHTML files onto the form, specify the conversion parameters and press the CONVERT button. Watch your XHTML turn into HTML within a minute. The output content and formatting will be identical to the original document.
The second XML advantage is portability. With XML, a single page can result in multiple outputs. After the markup and content is compiled into an XML (or in our case, an XHTML) document, various style sheets can be applied that control different outputs. And, who's to say that output is only for display.
