The generated output contains an inline style declaration.</p> </blockquote> <p>It also ensures that the HTML document is <code>xhtml</code> compatible </p> <h2>Example</h2> <pre><code>$code ='&lt;p&gt; &lt;strong&gt; &lt;span style="font-size: 14px"&gt; &lt;span style="color: #006400"&gt; &lt;span style="font-size: 14px"&gt; &lt;span style="font-size: 16px"&gt; &lt;span style="color: #006400"&gt; &lt;span style="font-size: 14px"&gt; &lt;span style="font-size: 16px"&gt; &lt;span style="color: #006400"&gt;This is a &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;span style="color: #006400"&gt; &lt;span style="font-size: 16px"&gt; &lt;span style="color: #b22222"&gt;Test&lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/span&gt; &lt;/strong&gt; &lt;/p&gt;'; </code></pre> <p>If you RUN </p> <pre><code>$clean = cleaning($code); print($clean['body']); </code></pre> <p>Output</p> <pre><code>&lt;p&gt; &lt;strong&gt; &lt;span class="c3"&gt; &lt;span class="c1"&gt;This is a&lt;/span&gt; &lt;span class="c2"&gt;Test&lt;/span&gt; &lt;/span&gt; &lt;/strong&gt; &lt;/p&gt; </code></pre> <p>You can get the CSS </p> <pre><code>$clean = cleaning($code); print($clean['style']); </code></pre> <p>Output</p> <pre><code>&lt;style type="text/css"&gt; span.c3 { font-size: 14px } span.c2 { color: #006400; font-size: 16px } span.c1 { color: #006400; font-size: 14px } &lt;/style&gt; </code></pre> <p>Our the FULL HTML </p> <pre><code>$clean = cleaning($code); print($clean['full']); </code></pre> <p>Output</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;title&gt;&lt;/title&gt; &lt;style type="text/css"&gt; /*&lt;![CDATA[*/ span.c3 {font-size: 14px} span.c2 {color: #006400; font-size: 16px} span.c1 {color: #006400; font-size: 14px} /*]]&gt;*/ &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;p&gt; &lt;strong&gt;&lt;span class="c3"&gt;&lt;span class="c1"&gt;This is a&lt;/span&gt; &lt;span class="c2"&gt;Test&lt;/span&gt;&lt;/span&gt;&lt;/strong&gt; &lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <h2>Function Used</h2> <pre><code>function cleaning($string, $tidyConfig = null) { $out = array (); $config = array ( 'indent' =&gt; true, 'show-body-only' =&gt; false, 'clean' =&gt; true, 'output-xhtml' =&gt; true, 'preserve-entities' =&gt; true ); if ($tidyConfig == null) { $tidyConfig = &amp;$config; } $tidy = new tidy (); $out ['full'] = $tidy-&gt;repairString ( $string, $tidyConfig, 'UTF8' ); unset ( $tidy ); unset ( $tidyConfig ); $out ['body'] = preg_replace ( "/.*&lt;body[^&gt;]*&gt;|&lt;\/body&gt;.*/si", "", $out ['full'] ); $out ['style'] = '&lt;style type="text/css"&gt;' . preg_replace ( "/.*&lt;style[^&gt;]*&gt;|&lt;\/style&gt;.*/si", "", $out ['full'] ) .
