Regular expression to match string and then specific numbers-CodePudding

I am trying to create a regular expression for a string entry with two components:

BV001ID is going to be the first part of the string, and it must always begin with this.

Then there will be a three digit number. The first digit must be either 0, 2, or 9. The following two digits can be any number.

So for example, a valid response can be BV001ID041. A valid response could not be BV001ID301 or BV001010.

This seems to be working for the three digit number: [0,2,9]\d\d

But I'm not sure how to add the string in front.

CodePudding user response：

You can just prefix literal characters into your regular expression. You should however remove the commas from the character class, as otherwise you actually allow a comma. Every single character in a character class represents a possible match, so only list those, like [029]

So do:

BV001ID[029]\d\d

Please try this \BV001ID[0,2,9]\d\d

Longhand version I came up with:

^BV001ID[0,2,9][0-9][0-9]
