正责表达式如何过滤html,取出中间的文字部分:如下面,如何使用正责表达式取出“我们去哪”
<span style="color:#ff3333;font-size:medium;"><strong>我们去哪</strong></span>


回复讨论(解决方案)

var str = '&lt;span style="color:#ff3333;font-size:medium;"&gt;&lt;strong&gt;我们去哪&lt;/strong&gt;&lt;/span&gt;';var reg = /\<[^\>]+\>/g;str = str.replace(/\&lt;?/g,"<").replace(/\&gt;?/g,">").replace(reg,"");console.log(str);

用正则占用资源,你这种情况可以不用正则来做。

$content = '&lt;span style="color:#ff3333;font-size:medium;"&gt;&lt;strong&gt;我们去哪&lt;/strong&gt;&lt;/span&gt;';echo strip_tags(htmlspecialchars_decode($content));
