How to grab string from a HTML document using Javascript -

i trying grab string html page. string lives inside div tag no id, , has ever changing title property.

it looks this:

<div title = [this title changes depending on how page pulled up]> emailaddress abc@xyz </div> 

i want able grab "abc@xyz" out of whole mess.

this html document ever changing, thing know sure stays same string want grab preceded "emailaddress"

i've been staring @ 3 hours no progress. i'd thankful if can point me in right direction.

without jquery:

var divelements = document.getelementsbytagname( 'div' );  ( var = 0; < divelements.length; i++ ) {     if ( divelements[i].innertext.match( 'emailaddress' ) ) {         // div          var mail_id =  divelements[i].innertext.replace('emailaddress ','');     } } 

see fiddle.
