php - How to extract an object tag from a text -

hi i've created system adds articles in database, user can embed youtube or dailymotion or simple flash text area. in home page, i've inserted slideshow slides new feed image, i've writen simple condition if checks if text contains embeded video using:

if (ereg('<object>',$text){} 

i want insert video(object element in general) in slide show in case there's object in text. in other words want extract what's between <object> , </object>

thank you

i'm not sure slideshow part or if trying modify content. extraction part there's 2 options. can use simple-minded regular expression like:

preg_match("#<object[^>]*>(.+?)</object>#ims", $text, $matches); print $matches[1]; 

or more reliable html parser readable api phpquery or querypath:

print qp($text)->find("object")->text(); 

the latter allow extract attributes more easily.
