Note Submitter: datacompboy at call2ru dot com ---- For example, you want to cut an some <div> element. Accurate, from <div> to correspond </div> element. Here is proof-of-concept code to do this: <? $str = "<dqiv1>1+<div2>2+<div3><b><c>3</c></b></div3>2-</div2>1-</div1>"; preg_match("#<div.> ( ". " ( (?>[^<]*) ( < ( ([^/d]|d([^i]|i[^v])) | /([^d]|d([^i]|i[^v])) ) )? )* ". " | (?R) )* </div.>#xi", $str, $m); var_dump($m[0]); ?> it match accurate from <div2> to </div2>. And, if you change <dqiv1> to <div1>, it will match from <div1> to </div1>
