title: Convert "pt" to "px" using regular expression
body: <p>In WYSIWYG editor, I have</p>
  
  <pre><code>&lt;TABLE style="WIDTH: 162pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=216&gt;
  </code></pre>
  
  <p>I can convert this to</p>
  
  <pre><code>&lt;TABLE style="WIDTH: 162px; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=216&gt;
  </code></pre>
  
  <p>using </p>
  
  <pre><code>"wysiwygdata".replace(/pt/g ,"px");
  </code></pre>
  
  <p>Is there any way to change associated value of pt to the value of px using regex.</p>
  
  <p>162pt might be 162*96/72px.</p>
  
  <p>Looking for your help.</p>
