Mozile (xhtml editing in your browser)
In all but the simplest cases, XHTML document editing means being able to change some areas of a page but not others. The overall look and perhaps the sidebars of a page are "fixed" but the meat of the page should be easy to change.
Mozile or Mozilla Inline Editor is an in-browser, context-sensitive, XHTML editor that allows a user to edit all or just specific editable sections of any XHTML page from the comfort of his own browser. It can act as the client-side of a content-editing system or as a self-contained "web word processor".
