It'd help if you could provide a better example of the HTML. You could try something like this:

#!/usr/bin/perl
use strict;
use warnings;
use feature 'say';
use Mojo::DOM;

my $html = '<div class="JMWMJ"><div class="toI8Rb OSrXXb usbThf">Sam N
+amett, MD - Physician - Interventional Orthopedics ...Exosomes are na
+novesicles (30-200 nm) found in extracellular space of various cell t
+ypes, and in biofluids; having diverse functions including intracellu
+lar ...</div></div>
<div class="JMWMJ"><div class="toI8Rb OSrXXb usbThf">Dr. Bombay - Phys
+ician - witch doctor ...canned laughter ...</div></div>
<div class="JMWMJ"><div class="toI8Rb OSrXXb usbThf">Dr. Who - time lo
+rd - previously good TV show ...</div></div>';

my $dom = Mojo::DOM->new( $html );

for my $entry ( $dom->find('div.JMWMJ')->each ){
    say $entry->all_text;
}

Outputting:

+e nanovesicles (30-200 nm) found in extracellular space of various ce
+ll types, and in biofluids; having diverse functions including intrac
