The objective of the package is to provide a fast and
essential HTML check (esp. for CGI scripts where response
time is important) to prevent a piece of user input HTML
code from messing up the rest of a file, i.e., to minimize
and localize any possible damage created by including a
piece of user input HTML text in a dynamic document.
HTMLQuickCheck checks for unmatched < and >, unmatched
tags and improper nesting, which could ruin the rest of
the document. Attributes and elements with optional end
tags are not checked, as they should not cause disasters
with any decent browsers (they should ignore any
unrecognized tags and attributes according to the
standard). A piece of HTML that passes HTMLQuickCheck may
not necessarily be valid HTML, but it would be very
unlikely to screw others but itself. A valid piece of HTML
that doesn't pass the HTMLQuickCheck is however very
likely to screw many browsers(which are obviously broken
in terms of strict conformance).
HTMLQuickCheck currently supports HTML 1.0, 2.x (draft),
3.0 (draft) and netscape extensions (1.1).
