String.split 函数在处理某些文本时无法正常工作

Question

I have string parser in node.js. Input string comes from telegram channel. Now I have serious problem with String.split function. It works with some types of text but it doesn't work with some other texts. When I receive not processed string in telegram, I just copy and send it in the channel again. In this case, parser processes it well. Is there any advise for this issue?

        let teams = [];
        teamSeps =[" vs ", " v ", " - ", " x " ,"-", " -"];
        for(let i = 0; i< teamSeps.length; i++){
            teams = newTip.Match.toLowerCase().split(teamSeps[i]);
            if(teams.length === 2) break;
        }
        newTip.Home = teams[0].trim();
        newTip.Away = teams[1].trim();
        return;

Instead of adding multiple options with optional spaces on either side of - , you can use a single regex with some alternation .

/\s*-\s*|\s+(?:vs|v|x)\s+/

• \\s*-\\s* : Allows optional space around -
• \\s+(?:vs|v|x)\\s+ : Allows at least one space around vs or v or x (Otherwise, if there is a x or v in the string, it will split)

 function customSplit(str) { return str.split(/\\s*-\\s*|\\s+(?:vs|v|x)\\s+/); } console.log(customSplit("Man United vs Man City")) console.log(customSplit("France - Croatia")) console.log(customSplit("Belgium-England")) console.log(customSplit("Liverpool x Spurs"))
