Hello i have question about write a pattern that will find all the emails at a webpage in a mailto syntax

i wrote something like this

$pattern_email = '[a-zA-Z0-9]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9]+[.a-zA-Z0-9]+?';
$pattern = '#<a href="?\'?mailto:'.$pattern_email.'"?\'?>('.$pattern_email.')</a>#';

But this pattern only works for so defined strings

<a href="mailto:email@domain.com">email@domain.com</a>

I need do something more complex to find for example somthing like this 

<a href="mailto:email@domain.com"><strong>email@domain.com</strong></a>

<a title="Linkinfication: mailto:email@domain.com" href="mailto:email@domain.com" class="any css class">email@domain.com</a> 

Is it just me or does anyone else think this is so more email spam can be sent?

wrrr *** and what shuld i do now i didn't expect such an answer the reson to do that, is that my buyer want to protect his allredy existing website, and the scritp is changing all the mailto tags into image you can se this here bayer.com.pl/email_filter/index and i told them that i can do this but i didnt expected such thing like this

http://www.bayer.com.pl/content/42/press_room/65  look at the and of the page there is a email but not protected

And now i  have problem with the buyer becouse he want the whole emails at the page protected.

Maybe someone can answer me at the pirvate ?

Please help i'm not expert in writing regural expression.

 

I suggest that you think about what you are actually trying to find here. You state in the original question that you are looking for the "mailto" items, but your pattern seems to restrict the search to only those instances that occur within the "<a>" tags and following an "href=" attribute.

Are you looking for ANY "mailto:name@email.address" structure or are there specific places where you need to look? If the former, then take away all of the other parts of your pattern, and if the latter then tell us where to find the text.
