class

Sanitize::Policy::Text

Inherits Sanitize::Policy / Reference / Object

Reduces an HTML tree to the content of its text nodes. It renders a plain text result, similar to copying HTML content rendered by a browser to a text editor. HTML special characters are escaped.

policy = Sanitize::Policy::Text.new
policy.process(%(foo &lt;strong&gt;&lt;a href=&quot;bar&quot;&gt;bar&lt;/a&gt;!&lt;/strong&gt;)) # =&gt; &quot;foo bar!&quot;
policy.process(%(&lt;p&gt;foo&lt;/p&gt;&lt;p&gt;bar&lt;/p&gt;))                        # =&gt; &quot;foo bar&quot;
policy.block_whitespace = &quot;\n&quot;
policy.process(%(&lt;p&gt;foo&lt;/p&gt;&lt;p&gt;bar&lt;/p&gt;)) # =&gt; &quot;foo\nbar&quot;
