请问大家是如何学习正则的?
今天终于学到正则表达式了
看上去压根就是比汇编还难看懂的超级"符号语言"，当然它的知识范围并不像汇编那样广，然而要掌握这些符号组合规则却必须费一翻功夫……

有时候看着书本去自己设计一些表达式来匹配字符却得不到自己所想的结果.马上意识到自己对其匹配规则或含义有所误解..
真的感觉好难记
不知道大家是怎么学习正则的，当然网上有好多资料，但都是教怎么匹配哪些字符串这样
我希望了解一下有什么学习方法可以顺利学会.
我现在想每天都匹配随机一篇文章里面3个不同组合方式的字符.这样来使自己慢慢熟悉正则

------解决方案--------------------
这可真没汇编难...
一个一个正则条件去写分析判断结果其实真不会太难，它的好处就是太能匹配了。所以只要不是太离谱瞎猫总能逮着老鼠哈哈
不过要说写一个效率十分之高的正则，这个可能就需要你通透这些组合咯。

用多了你会觉得并不如你想像的可怕。

试着写采集脚本

在线试玩。玩多了就会了。
