">

but in every case it makes an Error ! please some one help with this ...

尝试一下:

"(\d{2})([:])(\d{2})([:])(\d{2})

Try this:

"(\d{2})([:])(\d{2})([:])(\d{2})

"

我相信^是一个否定词，表示*不应*长度为2的数字


并用数字表示，您应该使用\
注意:请确保在字符串前使用转义符@，或将\替换为\\
[\ Edit]

"

I believe ^ is a negation, which means it should *not* be a digit of length 2


and to denote digit, you should be using \
Note: Make sure you have an escape @ character before the string, or replace the \ with \\
