RegexdrillTwo captures: major and minor version
A regex exercise from Regexdrill. Solve it with a pattern box with live highlighting in your browser, checked against hidden test strings, and it is checked the moment you submit.
The task
Find the first version tag written v, a number, a period and a number, like v2.14. Capture the major number in group 1 and the minor number in group 2. A v that is not followed by exactly that shape does not count.
What this exercise teaches
v(\d+)\.(\d+) captures the two numbers in order. With an unescaped period, v1x2 would also count, and without the v the pattern would pick up any decimal number earlier on the line.
A hint if you get stuck
Groups are numbered by their opening parenthesis, left to right. Escape the period between the two numbers.
