    26 			This sample page demonstrates the idea of Advanced Content Filter
    27 			(<abbr title="Advanced Content Filter">ACF</abbr>), a sophisticated
    28 			tool that takes control over what kind of data is accepted by the editor and what
    29 			kind of output is produced.
    30 		</p>
    31 		<h2>When and what is being filtered?</h2>
    32 		<p>
    33 			<abbr title="Advanced Content Filter">ACF</abbr> controls
    34 			<strong>every single source of data</strong> that comes to the editor.
    35 			It process both HTML that is inserted manually (i.e. pasted by the user)
    36 			and programmatically like:
    37 		</p>
    38 <pre class="samples">
    39 editor.setData( '&lt;p&gt;Hello world!&lt;/p&gt;' );
    40 </pre>
    41 		<p>
    42 			<abbr title="Advanced Content Filter">ACF</abbr> discards invalid,
    43 			useless HTML tags and attributes so the editor remains "clean" during
    44 			runtime. <abbr title="Advanced Content Filter">ACF</abbr> behaviour
    45 			can be configured and adjusted for a particular case to prevent the
    46 			output HTML (i.e. in CMS systems) from being polluted.
    47 
    48 			This kind of filtering is a first, client-side line of defense
    49 			against "<a href="http://en.wikipedia.org/wiki/Tag_soup">tag soups</a>",
    50 			the tool that precisely restricts which tags, attributes and styles
    51 			are allowed (desired). When properly configured, <abbr title="Advanced Content Filter">ACF</abbr>
    52 			is an easy and fast way to produce a high-quality, intentionally filtered HTML.
    53 		</p>
    54 
    55 		<h3>How to configure or disable ACF?</h3>
    56 		<p>
    57 			Advanced Content Filter is enabled by default, working in "automatic mode", yet
    58 			it provides a set of easy rules that allow adjusting filtering rules
    59 			and disabling the entire feature when necessary. The config property
    60 			responsible for this feature is <code><a class="samples"
    61 			href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">config.allowedContent</a></code>.
    62 		</p>
    63 		<p>
    64 			By "automatic mode" is meant that loaded plugins decide which kind
    65 			of content is enabled and which is not. For example, if the link
    66 			plugin is loaded it implies that <code>&lt;a&gt;</code> tag is
    67 			automatically allowed. Each plugin is given a set
    68 			of predefined <abbr title="Advanced Content Filter">ACF</abbr> rules
    69 			that control the editor until <code><a class="samples"
    70 			href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
    71 			config.allowedContent</a></code>
    72 			is defined manually.
    73 		</p>
    74 		<p>
    75 			Let's assume our intention is to restrict the editor to accept (produce) <strong>paragraphs
    76 			only: no attributes, no styles, no other tags</strong>.
    77 			With <abbr title="Advanced Content Filter">ACF</abbr>
    78 			this is very simple. Basically set <code><a class="samples"
    79 			href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
    80 			config.allowedContent</a></code> to <code>'p'</code>:
    81 		</p>
    82 <pre class="samples">
    83 var editor = CKEDITOR.replace( <em>textarea_id</em>, {
    84 	<strong>allowedContent: 'p'</strong>
    85 } );
    86 </pre>
    87 		<p>
    88 			Now try to play with allowed content:
    89 		</p>
    90 <pre class="samples">
    91 // Trying to insert disallowed tag and attribute.
    92 editor.setData( '&lt;p <strong>style="color: red"</strong>&gt;Hello <strong>&lt;em&gt;world&lt;/em&gt;</strong>!&lt;/p&gt;' );
    93 alert( editor.getData() );
    94 
    95 // Filtered data is returned.
    96 "&lt;p&gt;Hello world!&lt;/p&gt;"
    97 </pre>
    98 		<p>
    99 			What happened? Since <code>config.allowedContent: 'p'</code> is set the editor assumes
   100 			that only plain <code>&lt;p&gt;</code> are accepted. Nothing more. This is why
   101 			<code>style</code> attribute and <code>&lt;em&gt;</code> tag are gone. The same
   102 			filtering would happen if we pasted disallowed HTML into this editor.
   103 		</p>
   104 		<p>
   105 			This is just a small sample of what <abbr title="Advanced Content Filter">ACF</abbr>
   106 			can do. To know more, please refer to the sample section below and
   107 			<a href="http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter">the official Advanced Content Filter guide</a>.
   108 		</p>
   109 		<p>
   110 			You may, of course, want CKEditor to avoid filtering of any kind.
   111 			To get rid of <abbr title="Advanced Content Filter">ACF</abbr>,
   112 			basically set <code><a class="samples"
   113 			href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
   114 			config.allowedContent</a></code> to <code>true</code> like this:
   115 		</p>
   116 <pre class="samples">
   117 CKEDITOR.replace( <em>textarea_id</em>, {
   118 	<strong>allowedContent: true</strong>
   119 } );
   120 </pre>
   121 
   122 		<h2>Beyond data flow: Features activation</h2>
   123 		<p>
   124 			<abbr title="Advanced Content Filter">ACF</abbr> is far more than
   125 			<abbr title="Input/Output">I/O</abbr> control: the entire
   126 			<abbr title="User Interface">UI</abbr> of the editor is adjusted to what
   127 			filters restrict. For example: if <code>&lt;a&gt;</code> tag is
   128 			<strong>disallowed</strong>
   129 			by <abbr title="Advanced Content Filter">ACF</abbr>,
   130 			then accordingly <code>link</code> command, toolbar button and link dialog
   131 			are also disabled. Editor is smart: it knows which features must be
   132 			removed from the interface to match filtering rules.
   133 		</p>
   134 		<p>
   135 			CKEditor can be far more specific. If <code>&lt;a&gt;</code> tag is
   136 			<strong>allowed</strong> by filtering rules to be used but it is restricted
   137 			to have only one attribute (<code>href</code>)
   138 			<code>config.allowedContent = 'a[!href]'</code>, then
   139 			"Target" tab of the link dialog is automatically disabled as <code>target</code>
   140 			attribute isn't included in <abbr title="Advanced Content Filter">ACF</abbr> rules
   141 			for <code>&lt;a&gt;</code>. This behaviour applies to dialog fields, context
   142 			menus and toolbar buttons.
   143 		</p>
   144 
   145 		<h2>Sample configurations</h2>
   146 		<p>
   147 			There are several editor instances below that present different
   148 			<abbr title="Advanced Content Filter">ACF</abbr> setups. <strong>All of them,
   149 			except the inline instance, share the same HTML content</strong> to visualize
   150 			how different filtering rules affect the same input data.

The Apollo spacecraft had three parts:&lt;/p&gt; &lt;ol&gt; &lt;li&gt;&lt;strong&gt;Command Module&lt;/strong&gt; with a cabin for the three astronauts which was the only part which landed back on Earth&lt;/li&gt; &lt;li&gt;&lt;strong&gt;Service Module&lt;/strong&gt; which supported the Command Module with propulsion, electrical power, oxygen and water&lt;/li&gt; &lt;li&gt;&lt;strong&gt;Lunar Module&lt;/strong&gt; for landing on the Moon.&lt;/li&gt; &lt;/ol&gt; &lt;p&gt;After being sent to the Moon by the Saturn V&amp;#39;s upper stage, the astronauts separated the spacecraft from it and travelled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the &lt;a href=&quot;http://en.wikipedia.org/wiki/Mare_Tranquillitatis&quot; title=&quot;Mare Tranquillitatis&quot;&gt;Sea of Tranquility&lt;/a&gt;. They stayed a total of about 21 and a half hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the &lt;a href=&quot;http://en.wikipedia.org/wiki/Pacific_Ocean&quot; title=&quot;Pacific Ocean&quot;&gt;Pacific Ocean&lt;/a&gt; on July 24.&lt;/p&gt; &lt;hr/&gt; &lt;p style=&quot;text-align: right;&quot;&gt;&lt;small&gt;Source: &lt;a href=&quot;http://en.wikipedia.org/wiki/Apollo_11&quot;&gt;Wikipedia.org&lt;/a&gt;&lt;/small&gt;&lt;/p&gt;
