Removing leading whitespace from indented HTML source in pre/code tags

I currently have the following html within a pre-code block:

                <pre class="prettyprint"><code>
                    &lt;html&gt;
                    &lt;body&gt;

                    &lt;form name=&quot;input&quot; action=&quot;html_form_action.asp&quot; method=&quot;get&quot;&gt;
                    &lt;input type=&quot;radio&quot; name=&quot;sex&quot; value=&quot;male&quot;&gt;Male&lt;br&gt;
                    &lt;input type=&quot;radio&quot; name=&quot;sex&quot; value=&quot;female&quot;&gt;Female&lt;br&gt;
                    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
                    &lt;/form&gt; 

                    &lt;p&gt;If you click the &quot;Submit&quot; button, the form-data will be sent to a page called &quot;html_form_action.asp&quot;.&lt;/p&gt;

                    &lt;/body&gt;
                    &lt;/html&gt;
                </code></pre>

It is indented within the html source for better structure within the document. How can I remove the leading whitespace? Through the use of javascript or is there a more simple method.

Answer

You may want to just change how it is output, but it is fairly simple to do with JavaScript

var p = document.querySelector(".prettyprint");
p.textContent = p.textContent.replace(/^s+/mg, "");
