I am trying to clean up broken VTT files, where the lines show:
00:00.000 -- constituent 00:06.880 but instead should show
00:00.000 --> 00:06.880
VTT is written so that it’s MM:SS:MSMSMS, and minutes can be any value, so I tried to match that via a regexp using ^\d+\:\d+\.\d+$, which apparently should work and on some regexp testing places it matches at first, but then when I add additional content to the string the match fails.
How can I get the string between these two matches so that I can replace it with --> ? The word here (constituent) is variable and so I need a general regexp rather than just a match and replace for the string. Thanks!
>Solution :
You could use this regex and replace code:
const input = `
1
00:00.000 -- constituent 00:06.880
2
00:30.022 test-test 00:37.750`;
const result = input.replace(/^(\d[\d:.]+\d)\b.*?\b(\d[\d:.]+\d)$/gm, "$1 --> $2");
console.log(result);
