使用Regex比较字符串以识别完全相同的字符串

Question

I have a pattern like:

\[[0-9],([0-9]|1[0-4]),[0-9],([0-9]|1[0-4])]

that perfectly matches the strings that are in form of

eg

[1,1,1,2]
[5,6,5,7]

I want the string like

[1,1,1,2]kwfkbkkbdobug

be recognized as a false or invalid and not compatible with the pattern, while by using current pattern the string that I mentioned will be recognized as a valid string because it has a [1,1,1,2] string inside regardless of existence of kwfkbkkbdobug .

What would be the best pattern in order to satisfy the need?

Answer 1

Just make use of the beginning of line anchor and the end of line anchor:

^\[[0-9],([0-9]|1[0-4]),[0-9],([0-9]|1[0-4])]$

^ is the beginning of line anchor which matches only at the beginning of a line.

$ is the end of line anchor which matches only at the end of a line.
