Here is a nice solution for those who want to remove one tag from where two tags comes together.

<p>A paragraph</p>
<br>
<br>
<p>Another Paragraph</p>
<br>
<br>
<p>Another Paragraph</p>

So, if you have used blogger to post something, you may have noticed that when we click enter, it automatically interpreted as a tag.
:I have felt this problem in my blog too:

So the basic selector syntax using jQuery is

jQuery('document').ready(function() {
$( ' br + br').remove();
}

If you want ot remove one tag only within <pre> tags, then it comes like this

jQuery('document').ready(function() {
$( 'pre br + br').remove();
}

After loading the page, above example will converted to

<p>A paragraph</p>
<br>
<p>Another Paragraph</p>
<br>
<p>Another Paragraph</p>

Here is the final solution for those who want to remove All doubled tags.


jQuery('document').ready(function() {
 $( 'br + br').remove();
 }

And here is the solution for those who want to remove All doubled tags only within <pre> tags.


jQuery('document').ready(function() {
$( 'br + br').remove();
}

Below is other ways with jQuery. These will work. but above solution is recommended!

$('br').next('br').remove();

$('br').prev('br').remove();
