@ -94,32 +94,32 @@ Autoload compatibility
HTML Purifier attempts to be as smart as possible when registering an
autoloader, but there are some cases where you will need to change
your own code to accomodate HTML Purifier. These are those cases:
PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
Because spl_autoload_register() doesn't exist in early versions
of PHP 5, HTML Purifier has no way of adding itself to the autoload
stack. Modify your __autoload function to test
HTMLPurifier_Bootstrap::autoload($class)
For example, suppose your autoload function looks like this:
function __autoload($class) {
require str_replace('_', '/', $class) . '.php';
return true;
}
A modified version with HTML Purifier would look like this:
function __autoload($class) {
if (HTMLPurifier_Bootstrap::autoload($class)) return true;
require str_replace('_', '/', $class) . '.php';
return true;
}
Note that there *is* some custom behavior in our autoloader; the
original autoloader in our example would work for 99% of the time,
but would fail when including language files.
AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED

the existing __autoload() handler. Users need to explicitly

HTML Purifier will register the function for you. But if it is
declared afterwards, it will mysteriously not work. This
snippet of code (after your autoloader is defined) will fix it:
spl_autoload_register('__autoload')
Users should also be on guard if they use a version of PHP previous
to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
for you, which can collide with an autoloader that was added by *you*
later.

with large amounts of code (HTML Purifier included), don't like
autoloaders. We offer an include file that includes all of HTML Purifier's

// If /path/to/library isn't already in your include path, uncomment
// the below line:
// require '/path/to/library/HTMLPurifier.path.php';

Optional components still need to be included--you'll know if you try to
use a feature and you get a class doesn't exists error! The autoloader
can be used in conjunction with this approach to catch classes that are
missing. Simply add this afterwards:

maintenance/generate-standalone.php . The standalone version has the
benefit of having most of its code in one file, so parsing is much
faster and the library is easier to manage.
If HTMLPurifier.standalone.php exists in the library directory, you
can use it like this:
require '/path/to/HTMLPurifier.standalone.php';
This is equivalent to including HTMLPurifier.includes.php, except that
the contents of standalone/ will be added to your path. To override this
behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
be found (usually, this will be one directory up, the "true" library
directory in full distributions). Don't forget to set your path too!
The autoloader can be added to the end to ensure the classes are
loaded when necessary; otherwise you can manually include them.
To use the autoloader, use this:

HTML Purifier is an HTML filtering solution that uses a unique combination
of robust whitelists and agressive parsing to ensure that not only are
XSS attacks thwarted, but the resulting HTML is standards compliant.
HTML Purifier is oriented towards richly formatted documents from
untrusted sources that require CSS and a full tag-set. This library can
be configured to accept a more restrictive set of tags, but it won't be
as efficient as more bare-bones parsers. It will, however, do the job
right, which may be more important.

<p>The founder of Taiji was Zhang Sanfeng (Chang San-feng), who was a monk of the Wu Dang (Wu Tang) Monastery and lived in the period from 1391 to 1459. His exercises stressed suppleness and elasticity as opposed to the hardness and force of other martial art styles. Several centuries old, Taiji was originally developed as a form of self-defense, emphasizing strength, balance, flexibility and speed. Tai Chi also differs from other martial arts in that it is based on the Taoist religion and aims to avoid aggressive forces. </p>

HTML Purifier has a fairly complex system for configuration. Users
interact with a <code>HTMLPurifier_Config</code> object to
set configuration directives. The values they set are validated according
to a configuration schema, <code>HTMLPurifier_ConfigSchema</code>.
</p>
<p>
The schema is mostly transparent to end-users, but if you're doing development
work for HTML Purifier and need to define a new configuration directive,
you'll need to interact with it. We'll also talk about how to define
userspace configuration directives at the very end.

This needs to be marked accordingly. In the presentation, it might
make sense keep (3) separate, have (2) a sublist of (1). (1) can
be a closing tag, in which case (3) makes no sense at all, OR it
should be related with its opening tag (this may not necessarily
be possible before MakeWellFormed is run).
So, the line and column counts as our identifier, so:

One consideration about (1) is that it usually is actually a
(3) modification, but we have no way of knowing about that because
of various optimizations. However, they can probably be treated
the same. The other difficulty is that (3) is never a line and
column; rather, it is a range (i.e. a duple) and telling the user
the very start of the range may confuse them. For example,
