首先,要匹配任意内容“.”是不行的,因为不匹配“\n”,取不到想要的内容,所以有了如下表达式:
[\s\S]*当然,你也可以用 “[\d\D]*”、“[\w\W]*” 来表示。
现在我们来匹配一个html标签,匹配table如下:
<table.*""和一个却不加“"htmlcode">
<script> var str='<table>这是第一个table</table>'; str+='我不是table里的内容'; str+='<table>这是第二个table</table>'; str+='我也不是table里的内容'; str+='<table>这是第三个table</table>'; var reg1 = /<table.*"" src="/UploadFiles/2021-04-02/20200411131759.png">以上就是正则表达式替换table表格中的样式与空标记(保留rowspan与colspan)的详细内容,更多关于正则表达式替换table表格的资料请关注其它相关文章!

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
