lowercase, as validation will be done in a case-sensitive manner despite

Attr.ClassUseCDATA
|

TYPE: bool/null
|

DEFAULT: null
|

VERSION: 4.0.0
|
||||
--DESCRIPTION--
|
||||
If null, class will auto-detect the doctype and, if matching XHTML 1.1 or
|
||||
XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,
|
||||
it will use a relaxed CDATA definition. If true, the relaxed CDATA definition
|
||||
is forced; if false, the NMTOKENS definition is forced. To get behavior
|
||||
of HTML Purifier prior to 4.0.0, set this directive to false.
|
||||
|
||||
Some rational behind the auto-detection:
|
||||
in previous versions of HTML Purifier, it was assumed that the form of
|
||||
class was NMTOKENS, as specified by the XHTML Modularization (representing
|
||||
XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however
|
||||
specify class as CDATA. HTML 5 effectively defines it as CDATA, but
|
||||
with the additional constraint that each name should be unique (this is not
|
||||
explicitly outlined in previous specifications).

</p>

<li>Always applies to inline elements or text in the root node,</li>
|

<li>Applies to inline elements or text with double newlines in nodes

that allow paragraph tags,</li>
|
||||
<li>Applies to double newlines in paragraph tags</li>
|

</ul>
|

<p>
|

<code>p</code> tags must be allowed for this directive to take effect.

We do not use <code>br</code> tags for paragraphing, as that is
|
||||
semantically incorrect.
|
||||
</p>
|
||||
<p>
|
||||
To prevent auto-paragraphing as a content-producer, refrain from using
|
||||
double-newlines except to specify a new paragraph or in contexts where
|
||||
it has special meaning (whitespace usually has no meaning except in
|
||||
tags like <code>pre</code>, so this should not be difficult.) To prevent
|
||||
the paragraphing of inline text adjacent to block elements, wrap them
|
||||
in <code>div</code> tags (the behavior is slightly different outside of
|
||||
the root node.)

<p>

When enabled, HTML Purifier will attempt to remove empty elements that

of nodes will be removed:

</p>
|

<ul><li>

||||
Tags with no attributes and no content, and that are not empty

elements (remove <code><a></a></code> but not

<code><br /></code>), and
|
||||
</li>
|
||||
<li>
|
||||
Tags with no content, except for:<ul>
|
||||
<li>The <code>colgroup</code> element, or</li>
|
||||
<li>
|
||||
Elements with the <code>id</code> or <code>name</code> attribute,
|
||||
when those attributes are permitted on those elements.
|
||||
</li>
|
||||
</ul></li>
|
||||
</ul>
|
||||
<p>
|
||||
Please be very careful when using this functionality; while it may not
|
||||
seem that empty elements contain useful information, they can alter the
|
||||
layout of a document given appropriate styling. This directive is most
|
||||
useful when you are processing machine-generated HTML, please avoid using
|
||||
it on regular user HTML.
|
||||
</p>
|
||||
<p>
|
||||
Elements that contain only whitespace will be treated as empty. Non-breaking
|
||||
spaces, however, do not count as whitespace. See
|
||||
%AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
|
||||
</p>
|
||||
<p>
|
||||
This algorithm is not perfect; you may still notice some empty tags,
|
||||
particularly if a node had elements, but those elements were later removed
|
||||
because they were not permitted in that context, or tags that, after
|
||||
being auto-closed by another tag, where empty. This is for safety reasons
|
||||
to prevent clever code from breaking validation. The general rule of thumb:
|
||||
if a tag looked empty on the way in, it will get removed; if HTML Purifier
|
||||
made it empty, it will stay.

This parameter sets the maximum allowed length on <code>img</code> tags,

effectively the <code>width</code> and <code>height</code> properties.

Only absolute units of measurement (in, pt, pc, mm, cm) and pixels (px) are allowed. This is

This directive is similar to %HTML.MaxImgLength, and both should be

a unit).

absolutely no characters outside of the selected character encoding will be

to a UTF-8 specific <em>feature</em> that automatically resolves all

can be expressed in the non-UTF-8 encoding will be entity-ized, which can

be a real downer for encodings like Big5. It also assumes that the ASCII

If you would like users to be able to define external stylesheets, but

|

prevent them from fiddling with other elements, use this directive.
|
||||
It accepts any valid CSS selector, and will prepend this to any

||||
CSS declaration extracted from the document. For example, if this
|
||||
directive is set to <code>#user-content</code> and a user uses the
|
||||
selector <code>a:hover</code>, the final selector will be
|
||||
<code>#user-content a:hover</code>.

</p>
|
||||
<p>
|
||||
The comma shorthand may be used; consider the above example, with

<code>#user-content, #user-content2</code>, the final selector will

be <code>#user-content a:hover, #user-content2 a:hover</code>.

<p>
|

This directive turns on the style block extraction filter, which removes
|

<code>style</code> blocks from input HTML, cleans them up with CSSTidy,
|
||||
and places them in the <code>StyleBlocks</code> context variable, for further
|
||||
use by you, usually to be placed in an external stylesheet, or a
|
||||
<code>style</code> block in the <code>head</code> of your document.

<strong>Warning:</strong> It is possible for a user to mount an
|
||||
imagecrash attack using this CSS. Counter-measures are difficult;
|
||||
it is not simply enough to limit the range of CSS lengths (using
|
||||
relative lengths with many nesting levels allows for large values
|
||||
to be attained without actually specifying them in the stylesheet),
|
||||
and the flexible nature of selectors makes it difficult to selectively
|
||||
disable lengths on image tags (HTML Purifier, however, does disable
|
||||
CSS width and height in inline styling). There are probably two effective
|
||||
counter measures: an explicit width and height set to auto in all
|
||||
images in your document (unlikely) or the disabling of width and
|
||||
height (somewhat reasonable). Whether or not these measures should be
|
||||
used is left to the reader.

--DESCRIPTION--

<p>
|

This is a preferred convenience directive that combines
|

%HTML.AllowedElements and %HTML.AllowedAttributes.
|
||||
Specify elements and attributes that are allowed using:
|
||||
<code>element1[attr1|attr2],element2...</code>. For example,
|
||||
if you would like to only allow paragraphs and links, specify
|
||||
<code>a[href],p</code>. You can specify attributes that apply
|
||||
to all elements using an asterisk, e.g. <code>*[lang]</code>.
|
||||
You can also use newlines instead of commas to separate elements.

<strong>Warning</strong>:

VERSION: 2.0.0

--DESCRIPTION--
|

|

<p>
|
||||
Unique identifier for a custom-built HTML definition. If you edit
|
||||
the raw version of the HTMLDefinition, introducing changes that the
|
||||
configuration object does not reflect, you must specify this variable.
|
||||
If you change your custom edits, you should change this directive, or
|
||||
clear your cache. Example:
|
||||
</p>
|
||||
<pre>
|
||||
$config = HTMLPurifier_Config::createDefault();
|
||||
$config->set('HTML', 'DefinitionID', '1');

||||
$def = $config->getHTMLDefinition();
|
||||
$def->addAttribute('a', 'tabindex', 'Number');
|
||||
</pre>
|
||||
<p>
|
||||
In the above example, the configuration is still at the defaults, but
|
||||
using the advanced API, an extra attribute has been added. The
|
||||
configuration object normally has no way of knowing that this change
|
||||
has taken place, so it needs an extra directive: %HTML.DefinitionID.
|
||||
If someone else attempts to use the default configuration, these two
|
||||
pieces of code will not clobber each other in the cache, since one has
|
||||
an extra directive attached to it.
|
||||
</p>
|
||||
<p>
|
||||
You <em>must</em> specify a value to this directive to use the
|
||||
advanced API features.
