需要regEx这个。 [英] Need regEx for this.

问题描述

hi


我有一份文件，其中我必须在<之间找到Foto字样和>标签。我用这个正则表达式

hi
i have a document in which i have to find word "Foto" in between the "<" and ">" tags. i used this regex

"<(?:\w*)?Foto(?:\w*)?>"

如果字符串只有字母，这个工作正常标签之间的单词，但是有任何特殊字符然后它找不到。就像这样..

this is working fine if there is a string with only alphabetic words in between the tags, but is there is any speacial character then it fails to find.like this..

<hello world Foto:abc> ..... Find ok
<hello "world Foto:abc>.....Find fail

推荐答案

你好Choudhary，





\w 正则表达式：< b>任何单词字符（字母，数字，下划线）

您可以使用 。 （点）表示：任何单个字符



祝你好运，

Hello Choudhary,


\w in regex means: any word character (letter, number, underscore)
you may use . (dot) that means: any single character

Good luck,
Edo
