Regex for blockquotes to indent multiple paragraphs
<p>I want to intend multiple paragraph in <code>blockquote</code>, for example please see the image <a href="https://i.stack.imgur.com/VUKM3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VUKM3.png" alt="multiple paragraph intended in blockquote"></a></p>

<p>The <code>RegEx</code> expression for this  which I am using:</p>

<pre><code> /^( *&gt;[^\n]+(\n(?!def)[^\n]+)*\n*)+
</code></pre>

<p>By using this <code>RegEx</code> expression I am getting result like this:</p>

<p><a href="https://i.stack.imgur.com/qZmoG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qZmoG.png" alt="enter image description here"></a></p>

<p>The <code>RegEx</code> expression is from <code>marked.js</code> file. I have modified this expression to obtain the result but failed to obtain. I am not having good understanding of <code>RegEx</code>.</p>
