How to extract an object tag from a text

Hi I've created a system that adds articles in the database, the user can embed youtube or dailymotion or simple flash into the text area. In the home page, I've inserted a slideshow that slides new feed with image, I've writen a simple condition if t开发者_JS百科hat checks if the text contains an embeded video using:

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

I just want to insert the video(object element in general) in the slide show in case there's an object in the text. in other words I want to extract what's between <object> and </object>

thank you

I'm not sure about the slideshow part or if you are also trying to modify the content. But for the extraction part there's two options. You can use a simple-minded regular expression like:

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

Or a more reliable HTML parser with a readable API like phpQuery or QueryPath:

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

The latter would also allow you to extract attributes more easily.
