There is a bunch of stuff written in Perl that has lots and lots of functionality I do not want or need so I use the parts I want and skip the other stuff. I could rewrite it but why?

In this case you have supplied us with an input file that does not appear to be valid HTML, is incomplete, or both. I took the libertty of closing a few tags just to get the parser to stop complaining:

<r>
<div class="JMWMJ">
  <div class="toI8Rb OSrXXb usbThf">Sam Namett, MD - Physician - Inter
+ventional Orthopedics ...Exosomes are nanovesicles (30-200 nm) found 
+in extracellular space of various cell types, and in biofluids; havin
+g diverse functions including intracellular ...
  </div>
  <div class="Xxy7Vb">
      <div class="BtwlAd">
          <g-img style="width:16px;height:16px">
            <img id="dimg_8" src="data:image/gif;base64,R0lGODlhAQABAI
+AAAP///////yH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" />
          </g-img>
      </div>
  </div>
</div>
</r>

Now to parse and grab a single element:

perl -MXML::Simple -e 'my $x = qq~./limit.html~; system cat =>$x; my $
+rx = XMLin($x); use Data::Dumper; print Dumper \$rx; print qq~\n\n$rx
+->{div}->{div}->[0]->{content}~;'

Produces...

$VAR1 = \{                                                            
+                                                                
            'div' => {                                                
+                                                                
                     'div' => [                                       
+                                                                
                              {

The most interesting part being print qq~\n\n$rx->{div}->{div}->[0]->{content}~;

My point is this: if your input is legit then parsing and extracting from it becomes easier. Perhaps rather than rewrite a big script work on cleaning up the input for now and work on the script later when you have more time.
