TODO List = KEY ==================== # Flagship - Regular ? Maybe I'll Do It ========================== If no interest is expressed for a feature that may required a considerable amount of effort to implement, it may get endlessly delayed. Do not be afraid to cast your vote for the next feature to be implemented! 3.1 release [Error'ed] # Error logging for filtering/cleanup procedures - XSS-attempt detection 3.2 release [Do What I Mean, Not What I Say] # Additional support for poorly written HTML - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!) - Friendly strict handling of
(block ->
) - Remove redundant tags, ex. Underlined. Implementation notes: 1. Analyzing which tags to remove duplicants 2. Ensure attributes are merged into the parent tag 3. Extend the tag exclusion system to specify whether or not the contents should be dropped or not (currently, there's code that could do something like this if it didn't drop the inner text too.) - Remove tags that don't do anything (no attributes) - Remove empty inline tags - Append something to duplicate IDs so they're still usable (impl. note: the dupe detector would also need to detect the suffix as well) - Externalize inline CSS to promote clean HTML 3.3 release [It's All About Trust] (floating) # Implement untrusted, dangerous elements/attributes # Implement IDREF support (harder than it seems, since you cannot have IDREFs to non-existent IDs) # Frameset XHTML 1.0 and HTML 4.01 doctypes 4.0 release [Beyond HTML] # Legit token based CSS parsing (will require revamping almost every AttrDef class). Probably will use CSSTidy class # More control over allowed CSS properties (maybe modularize it in the same fashion!) # Formatters for plaintext - Smileys - Standardize token armor for all areas of processing - Convert RTL/LTR override characters to tags, or vice versa on demand. Also, enable disabling of directionality 5.0 release [To XML and Beyond] - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX) - Hooks for adding custom processors to custom namespaced tags and attributes, offer default implementation - Lots of documentation and samples Ongoing - Lots of profiling, make it faster! - Plugins for major CMSes (COMPLEX) - phpBB - eFiction - more! (look for ones that use WYSIWYGs) - Complete basic smoketests Unknown release (on a scratch-an-itch basis) # CHMOD install script for PEAR installs ? Have 'lang' attribute be checked against official lists, achieved by encoding all characters that have string entity equivalents - Abstract ChildDef_BlockQuote to work with all elements that only allow blocks in them, required or optional - Reorganize Unit Tests - Reorganize configuration directives (Create more namespaces! Get messy!) - Advanced URI filtering schemes (see docs/proposal-new-directives.txt) - Implement lenient child validation - Explain how to use HTML Purifier in non-PHP languages / create a simple command line stub (or complicated?) - Fixes for Firefox's inability to handle COL alignment props (Bug 915) - Automatically add non-breaking spaces to empty table cells when empty-cells:show is applied to have compatibility with Internet Explorer Requested Wontfix - Non-lossy smart alternate character encoding transformations (unless patch provided) - Pretty-printing HTML: users can use Tidy on the output on entire page - Native content compression, whitespace stripping (don't rely on Tidy, make sure we don't remove from
 or related tags): use gzip if this is
   really important
