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.

最佳回答

如果你想要通过<代码>regexp来做到这一点,则情况不佳。

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

但是,有更好的办法。
