htmLawed is a PHP script that makes input text more secure, HTML standards-compliant, and suitable in general from the viewpoint of a Web-page administrator, for use in the body of HTML 4 or XHTML 1 or 1.1 documents. It is a customizable HTML/XHTML filter, processor, purifier, and sanitizer. It can ensure that HTML tags are balanced and properly nested tags, neutralize code that may be used for cross-site scripting (XSS) attacks, and limit the allowed HTML elements, tags, attributes, or URL protocols.
PottyMouth transforms completely unstructured and untrusted text to valid, nice-looking, completely safe XHTML. PottyMouth is designed to handle input text from non-technical, potentially careless, or malicious users. It produces HTML that is completely safe, programmatically and visually, to include on any Web page. You don't need to make your users read any instructions before they start typing. They don't even need to know that PottyMouth is being used.
JHighlight is an embeddable Java syntax highlighting library that supports Java, Groovy, C++, HTML, XHTML, XML, and LZX languages and outputs to XHTML. The library can be used in several ways: embedded into another tool (for instance a blog or forum), through the command-line to generate highlighted files locally, or as a servlet filter to highlight source files on your server on-the- fly. It also supports RIFE templates tags and highlights them clearly so that you can easily identify the difference between your RIFE markup and the actual marked up source.
RetroWeb is an extension for RetroForth intended to ease the task of creating Web pages. It is still close to HTML, but offers a more compact syntax. Most importantly, it allows you to work with the full power of Forth to generate HTML code. It can be used to create both static HTML files and simple dynamic CGI responses.
