I tried the following regex patterns and none would work Number With Whitespaces, Dots or Hyphens. Lets start with a simple expression that will check if the number has ten digits and nothing else: This expression will allow numbers like 2055550125. if my $code is 0800 then my pattern should searchĪBCD23RT-WXYZFG4D-1234560800-C - will match the patternĪBDC4567-XYZW9000-1234560801-C - will not match Regular Expressions to Validate Phone Numbers.

The before the dash and period escapes these. Matches 5 numeric digits, such as a zip code. First 4 chars will be either ABCD or IJKL or WXYZ ,next 4 chars will be any word, followed by a hyphen -, then next 4 chars will be again ABCD The - (which indicates a hyphen) must occur last in the list of characters within the square brackets.

I have another file that i need to search for lines with pattern something like We only want one hyphen between each number sequence thus: 2-34-515 Thanks for your help Cheers, L. I am reading the contents like $codes = Get-Content $FileContainingCodes. 4 digit codes are listed in a file [ each code is in a separate lineĢ. Regex flavors are quite inconsistent about this.Need help in creating regex for the following situationġ. Hyphens at other positions in character classes where they can’t form a range may be interpreted as literals or as errors. This works in all flavors discussed in this tutorial. and match any character that is not an x or a hyphen. The hyphen can be included right after the opening bracket, or right before the closing bracket, or right after the negating caret. First 3 characters are upper case alphabets followed by four numbers followed by a hyphen followed by 2 upper case alphabets. In fact most regex variants has the same rule for matching hyphen If a bracket expression specifies both '-' and ']', the ']' shall be placed first (after the '^', if any) and the '-' last within the bracket expression. To use a as the starting range point, it shall either come first in the bracket expression or be specified as a collating symbol for example, "-0]", which matches either a or any character or collating element that collates between and 0, inclusive. As examples, the expressions "" and "" are equivalent and match any of the characters 'a', 'c', or '-' "" and "" are equivalent and match any characters except 'a', 'c', or '-' the expression "" matches any of the characters between '%' and '-' inclusive the expression matches any of the characters between '-' and inclusive and the expression is either invalid or equivalent to because the letter 'a' follows the symbol '-' in the POSIX locale.
The character shall be treated as itself if it occurs first (after an initial '^', if any) or last in the list, or as an ending range point in a range expression. To include a ‘-’, write ‘-’ as the first or last character of the set, or put it after a range.
