<p>I know this is a very old question but it still doesn't have an accepted answer. I see that you want the following removed: html tags that are "empty" and white spaces based on an html string.</p>

<p>I have come up with a solution based on your comment for the output you are looking for:</p>

<pre><code>Trimming using JavaScript&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;all leading and trailing white spaces 
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var str = "&lt;p&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt;&lt;div&gt;&amp;nbsp;&lt;/div&gt;Trimming using JavaScript&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;all leading and trailing white spaces&lt;p&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt;&lt;div&gt;&amp;nbsp;&lt;/div&gt;";
console.log(str.trim().replace(/&amp;nbsp;/g, '').replace(/&lt;[^\/&gt;][^&gt;]*&gt;&lt;\/[^&gt;]+&gt;/g, ""));</code></pre>
</div>
</div>
</p>

<p><code>.trim()</code> removes leading and trailing whitespace</p>

<p><code>.replace(/&amp;nbsp;/g, '')</code> removes <code>&amp;nbsp;</code></p>

<p><code>.replace(/&lt;[^\/&gt;][^&gt;]*&gt;&lt;\/[^&gt;]+&gt;/g, ""));</code> removes empty tags</p>


blocks|key|387144|text|01)。如果只需要删除前导空格和尾随空格，请使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|387145|var+address+=+"++No.255+Colombo++"
address.replace(/%5E[+]%2B%7C[+]%2B$/g,'');|code-block|syntax|javascript|387146|这将返回字符串"No.255科伦坡“|387147|02)。如果您需要删除所有空格，请使用以下命令：|387148|var+address+=+"++No.255+Colombo++"
address.replace(/\s/g,"");|387149|这将返回字符串“No.255科伦坡”|387150|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|U|8|@]|9|@]|A|$E|F]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

<p>01). If you need to remove only leading and trailing white space use this:</p>

<pre><code>var address = "  No.255 Colombo  "
address.replace(/^[ ]+|[ ]+$/g,'');
</code></pre>

<p>this will return string "No.255 Colombo"</p>

<p>02). If you need to remove all the white space use this:</p>

<pre><code>var address = "  No.255 Colombo  "
address.replace(/\s/g,"");
</code></pre>

<p>this will return string "No.255Colombo"</p>


<p>I've the following HTML string. What would be sample code in JavaScript to remove leading and trailing white spaces from this string?</p>

<pre><code>&lt;p&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt;
&lt;div&gt;&amp;nbsp;&lt;/div&gt;

&lt;br /&gt;

&lt;p&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt;
&lt;div&gt;&amp;nbsp;&lt;/div&gt;
