Answer

Regex for Validating "Корп 1, стр 3"

1. Clear Understanding of Requirements

The task is to create a regex that will validate a string in the format of "Корп [number], стр [number]".

  • "Корп" is in Cyrillic.
  • The numbers can be one or more digits.
  • The phrase has a comma followed by a space before "стр".

2. Key Elements Identification

  • Fixed text: "Корп" and "стр".
  • Number: One or more digits (0-9).
  • Special characters: Comma and space separating the two parts.

3. Constructing the Regular Expression

The regex needs to represent the pattern described. Here’s how we can construct it:

  • Корп matches the literal string "Корп".
  • \s? allows for an optional space character.
  • \d+ matches one or more digits, representing the number.
  • A comma followed by a space ,\s is used to separate "Корп" and "стр".
  • стр matches the literal string "стр".
  • Again, \s? allows for an optional space before the next digit.
  • Another \d+ matches the number after "стр".

Final Regex

^Корп\s*\d+,\s*стр\s*\d+$

4. Explanation of Components

  • ^ asserts the start of the string.
  • Корп matches the literal text.
  • \s* allows for zero or more whitespace characters.
  • \d+ matches one or more digits (1-9).
  • , matches the literal comma character.
  • \s* allows for zero or more whitespace characters after the comma.
  • стр matches the literal text.
  • \s* allows for zero or more whitespace characters before the number after "стр".
  • \d+ matches one or more digits at the end.
  • $ asserts the end of the string.

5. Testing and Validation

You can test this regex in any programming language that supports regex, such as Python, JavaScript, or Java. Here’s a quick example in Python:

import re

pattern = r'^Корп\s*\d+,\s*стр\s*\d+$'
test_strings = ["Корп 1, стр 3", "Корп 10, стр 24", "Корп 2,стр 5"]

for s in test_strings:
    if re.match(pattern, s):
        print(f"Valid: {s}")
    else:
        print(f"Invalid: {s}")

6. Usage Guidance

  • Implement this regex in your preferred programming environment.
  • Ensure the regex engine you are using supports Unicode if you're working with Cyrillic characters.
  • Adjust any white spaces (\s*) based on your specific formatting needs in the string.
