Code Quality Issues
Okay, face it. Programmers can get lazy, cut corners, or make mistakes. They
also can do quick prototypes, and then forget to rewrite them later. Well,
while I can't list mistakes in here, I can list prototype-like segments
of code that should be aggressively refactored. This does not list
optimization issues, that needs to be done after intense profiling.
docs/examples/demo.php - ad hoc HTML/PHP soup to the extreme
AttrDef - a lot of duplication, more generic classes need to be created;
a lot of strtolower() calls, no legit casing
Class - doesn't support Unicode characters (fringe); uses regular expressions
Lang - code duplication; premature optimization
Length - easily mistaken for CSSLength
URI - multiple regular expressions; missing validation for parts (?)
CSS - parser doesn't accept advanced CSS (fringe)
Number - constructor interface inconsistent with Integer
Strategy
FixNesting - cannot bubble nodes out of structures, duplicated checks
for special-case parent node
RemoveForeignElements - should be run in parallel with MakeWellFormed
URIScheme - needs to have callable generic checks
mailto - doesn't validate emails, doesn't validate querystring
news - doesn't validate opaque path
nntp - doesn't constrain path
