Extensible Hypertext Markup Language (XHTML) Training and Certification

XHTML is derived from Extensible Markup Language, which is the extended version of widely used Hypertext Markup Language, the language that is used for the creation of web pages.

HTML requires a tolerant HTML-parser whereas XTML can be parsed with the aid of normal XML parsers. HTML, prior to HTML5 was defined as an application of Standard Generalized Markup Language (SGML), while XHTML is an application of XML.

Though, SGML is a flexible markup language framework, the application of XML makes the documents of XHTML well-formed and therefore is a restrictive subset of SGML.

1. The web pages will contain XML tags that are properly closed and nested all the time, which is a major benefit over sloppy HTML tags For example; <p><b><u>I love music<br /><br /></u></b></p> instead of <p><b><u>I love music<br><br></b></u>
2. The documents of XHTML are edited, reviewed and validated in advance using the standard XML tools such as MSXML parser and hence they are XML conforming
3. The XML DOM (Document Object Model) or HTML DOM provides a way to XHTML documents to rely on either of them for the utilization of applications
4. XHTML defines quality standard to your websites and if you comply with Free Reprint Articles, then your web pages are included under the top quality web pages. The W3C certifies those same pages with their quality seal
