正则表达式中带*的电话号码

Question

I have created a regex for phone numbers as follows \\\\d+ ?\\\\w{0,9} ?\\\\d+ . Now i have a problem that this only accepts numbers. Sometimes i receive the phone number as starified so it can be 011***1334. How can i incorporate the stars portion into the above regex expression.

Answer 1

I'm having trouble getting your regex to work in the first place, without stars,

but anyway... you can represent the star by escaping it.

\\*

So you should just turn all of your \\d into [\\d\\*] or [\\\\d\\\\*] if you have to escape the \\ first in your java.

Some regular expression engines don't require you to escape all special characters in [] so I'd watch for that behavior if it doesn't work at first

Answer 2

Anywhere you use \\\\d , turn it into [\\\\d\\\\*]

[\\d\\*]+ ?\\w{0,9} ?[\\d\\*]+

I agree with Sam I am though; the original seems odd. If you just need numbers and asterisks, this should do (escaped Java-style):

[\\d\\*]{7,10}
