XHTML stands for “Extensible Hypertext Markup Language”, a text-based markup language that structures and semantically marks up content such as text, images and hyperlinks in documents. This markup language allows the editing of websites and as a reformulation of HTML 4.01, but with stricter and more versatile rules.
The use of XML as a meta markup language creates a strict version, which is particularly important for modern end devices with XML-based data formats. XHTML structures content such as text, images and hyperlinks to create a browser-friendly structure. A parser makes the documents readable by interpreting the prescribed markup elements and rendering the content accordingly.
Developed to bridge the gap between XML and HTML, XHTML uses the simple syntax and semantic language of XML. It enables uncomplicated data exchange, flexible automation and extensive formulation of texts and hyperlinks.
