Capturing a email genetating via javascript

[troshan]

I'm using "simplehtmldom" to captured the elements.

I want to capture the email address from the following

 

the email is generating with javascript and It was decoded. So I know I can not capture the email.

I noticed, I couldn't select the "output" or It's child element for some reasons.

$myemail = $item->find ('#field_11 .output');

So I captured the whole div by following method

$myemail = $item->find ('#field_11');

and which out puts the following result.

I guess If I remove the <!-- I'll able to print the value. I was trying to trim the <!-- by follwing method but none of them work

trim($myemail, "!--//");

trim(strip_tags($myemail), "!--//");

trim(htmlentities($myemail), "!--//");

I was trying to decode the result by following functions but none of them work (I guess using REGEX I can extract the email after decode)

html_entity_decode
htmlspecialchars_decode
utf8_decode

Could anyone help me to achieve what I want? Please ignore if any of my method distract you from providing a right solution.
