WackoWiki is a small, lightweight, handy, expandable Wiki clone. Its main advantages are a visual (WYSIWYG) editor, an easy installer, full Russian support, many localizations, email notification on changes/comments, several cache levels, design themes (skins) support, XHTML compliance, page rights (ACLs), and page comments.
wiki2xhtml can create complete Web pages and uses a clean XHTML syntax. It can insert galleries, a menu, a footer, and nearly all elements you know from the Wikipedia. The pages are formatted with CSS. All designs can be adjusted by hand, and custom ones can be used as well. wiki2xhtml generates the HTML pages from simple text files in the MediaWiki syntax. You can also use own (X)HTML code or other script languages inside; there are no restrictions. The GUI is composed of a Code Paste Window where you can insert wiki code that will be generated live. A click into the result, the XHTML code, copies it into the clipboard.
UverseWiki is a modular open source PHP framework designed for text processing. Unlike most existing solutions, it is not regular expression-based but instead uses a recursive descent parser to build a document object model. After the parsing stage has been finished and the DOM is produced, the original source is discarded and all operations are performed on the document tree instead: nodes can be altered, serialized, or rendered into a particular format (such as HTML or RTF). The wiki syntax is language-neutral and the processing itself is carried out in UTF-8.
