<h3>正则表达式大全</h3>
<p>正则表达式是一种用于描述和操作文本的语言，它可以用来搜索、编辑和替换文本。正则表达式的语法是由一个或多个字符组成的模式，可以用来匹配一个或多个字符串。正则表达式可以用于任何编程语言，但是不同的编程语言有不同的正则表达式语法。</p>

<h3>使用正则表达式</h3>
<p>正则表达式可以用于任何编程语言，但是不同的编程语言有不同的正则表达式语法。例如，JavaScript中的正则表达式语法和Python中的正则表达式语法是不同的。正则表达式可以用来搜索、编辑和替换文本，也可以用来验证文本是否符合某个格式，例如验证电子邮件地址是否有效。</p>

<h3>最常用的正则表达式</h3>
<ul>
	<li>匹配字符串中的数字：<pre>/\\d+/</pre></li>
	<li>匹配字符串中的字母：<pre>/[a-zA-Z]+/</pre></li>
	<li>匹配字符串中的数字和字母：<pre>/[a-zA-Z0-9]+/</pre></li>
