Converting <br> Tags to <Div> or <P> Tags

I am receiving HTML that is in various formats and I'm trying to standardize the code using jQuery. In some cases I receive it using breaks <br> to separate lines. I need these to be <div> (or <p>) tags instead. For instance the following code:

a<br>b<br>c

needs to be converted into

<div>a</div><div>b</div><div>c</div>

This is a simple case as the contents in a could be surrounded by all kinds of <font>, <span> and other formatting options, all of which need to be retained.

Here was my first attempt. It finds all the <br> tags in the entire document then accesses the parent's contents to get all the HTML around the <br>. If the contents length is 1 then <br> is the only element in there (meaning a blank line) so skip on to the next one. Otherwise look at each element, surround it with <div> (or <p>) and remove the <br> as it isn't needed any more. Variable wrapper is either "<div />" or "<p />" depending on the browser.

$("br").each(function() {
  // Find all the br tags' parent nodes
  var elements = $(this).parent().contents();
  if (elements.length > 1) {
    // If there is one element than it is br so skip on.
    elements.each(function() {
      // Loop through each child element of the parent 
      var nodeName = this.nodeName.toLowerCase();
      if (nodeName !== 'div' && nodeName !== 'p') {
      // Make sure each child that is not <br> is wrapped. Remove <br> tags.
        if (nodeName == 'br') {
          $(this).remove();
        } else {
          $(this).wrap(wrapper);
        }
      }
    });
  }
});

This doesn't work, though, as it adds <div> (or <p>) tags around every sub-element so something like <font>a</font>bc<br>de<b>f</b> ends up like

<div><font>a</font></div>
<div>bc</div>
<div>de</div>
<div><b>f</b></div>

when it really needs to be

<div><font>a</font>bc</div>
<div>de<b>f</b></div>

(I broke it up to be easier to read.)

If I was doing this in a text parser, I'd find the contents just like I did above for variable elements, add a <div> at the beginning and a </div> at the end, then replace each <br> with </div><div> (except when it is already <div><br></div>, at which point I'd skip it). I have no idea how to do this in jQuery/Javascript. though, especially regarding the replace <br> with </div><div> portion. (The first part is elements.wrap(wrapper).)

Any help on this approach or an alternative approach would be appreciated.

--- UPDATE ---

@Ian supplied must of the code that worked. I expanded on it just a little and thought I'd include it here. I have tested it in FF, Safari, Chrome and IE 9+.

$("br").each(function(idx, el) {
    var $el = $(el),
        $parent = $el.parent(),
        $contents = $parent.contents(),
        $cur, $set, i;

    $set = $();
        if ($contents.length > 1) {
        for (i = 0; i < $contents.length; i++) {
            $cur = $contents.eq(i);

            if ($cur.is("br")) {
                $set.wrapAll(wrapper);
                $cur.remove();
                $set = $();
            } else {
                $set = $set.add($cur);
            }
        }
        $set.wrapAll(wrapper);
    }
});

My suggestion will be to split the text by <br>:

var lines = content.split("<br>");

Now you can wrap each line in a <div>:

var newContent = "";
for(var i=0,l=lines.length;i<l;i++){
     newContent += "<div>"+lines[i]+"</div>";

}
