NAME

HTMLQuickCheck.pm --- a simple and fast HTML syntax checking package forperl 4 and perl 5

SYNOPSIS

    require 'HTMLQuickCheck.pm';

    &HTML'QuickCheck'OK($html_text) || die "Bad HTML: $HTML'QuickCheck'Error";

    or for perl 5:    HTML::QuickCheck::OK($html_text) ||             die "Bad HTML: $HTML::QuickCheck::Error";

DESCRIPTION

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 pieceof user input HTML code from messing up the rest of a file, i.e., tominimize and localize any possible damage created by including a piece ofuser input HTML text in a dynamic document.

HTMLQuickCheck checks for unmatched < and >, unmatched tags and impropernesting, which could ruin the rest of the document. Attributes andelements with optional end tags are not checked, as they should not causedisasters with any decent browsers (they should ignore any unrecognizedtags and attributes according to the standard). A piece of HTML thatpasses HTMLQuickCheck may not necessarily be valid HTML, but it would bevery unlikely to screw others but itself. A valid piece of HTML thatdoesn't pass the HTMLQuickCheck is however very likely to screw manybrowsers(which are obviously broken in terms of strict conformance).

HTMLQuickCheck currently supports HTML 1.0, 2.x (draft), 3.0 (draft) andnetscape extensions (1.1).

EXAMPLE

    htmlchk, a simple html checker:

    #!/usr/local/bin/perl    require 'HTMLQuickCheck.pm';    undef $/;    print &HTML'QuickCheck'OK(<>) ? "HTML OK\n" :             "Bad HTML:\n", $HTML'QuickCheck'Error;    __END__

    Usage:     htmlchk [html_file]
