Question

I need to find out the content before <img> tag in my HTML if it does not have <br/> before it. And if <img> jas some other content before it then I need to add <br/> before it.

Answer 1

Consider this html code :- (This solution uses JQuery!)

<h1><img src="#"/><h1>
<br/><img src="#"/>

Now in one case you need to get the element before <img>

  $(document).ready(
function(){
 $('img').each(function(){
  if($(this).prev()==$('br'))
   {
      $(this).prev().replaceWith('');
   }
   if($(this).prev()!=$('br)')
        {
          $(this).prev().replaceWith('br');
        }
});

});

Guess this would solve your problem.
