使用正则表达式帮助获取span id中的内容

Question

I want to get the value inside a span id or div id. For example from <span id="lastPrice">29.00</span> i want to get the 29.00. please help.

Answer 1

If you want to do this through regexp that badly.

$string = "<span id=\"lastPrice\">29.00</span>";
preg_match("/\<span id\=\"lastPrice\"\>([\d.]+?)\<\/span\>/",$string,$match);
print "<pre>"; var_dump($match[1]); print "</pre>";

But there are far more better ways.
