WYMeditor - web-based XHTML editor - Home

http://www.wymeditor.org/ WYMeditor's main concept is to leave details of the document's visual layout , and to concentrate on its structure and meaning, while trying to give the user as much comfort as possible (at least as WYSIWYG editors). WYMeditor has been created to generate perfectly structured XHTML strict code, to conform to the W3C XHTML specifications and to facilitate further processing by modern applications. With WYMeditor, the code can't be contaminated by visual informations like font styles and weights, borders, colors, ... The end-user defines content meaning, which will determine its aspect by the use of style sheets. The result is easy and quick maintenance of information .
markItUp! is not meant to be a “Full-Features-Out-of-the-Box”-editor. Instead it is a very lightweight, customizable and flexible engine made to meet the developer's needs in their CMSes, blogs, forums or websites. markItUp! is not a WYSIWYG editor, and it never will be. Fast and unobtrusive integration http://markitup.jaysalvat.com/home/
