I would like to split a string where the delimiter is a pipe. But the pipe can be escaped and not splitted than.
example:
'aa|bb|cc'.split(/*??*/) // ['aa','bb','cc']
'aa\|aa|bb|cc|dd\|dd|ee'.split(/*??*/) // ['aa|aa', 'bb', 'cc', 'dd|dd', 'ee']
I try this, but it not work in javascript: (?<!\\)[\|]
Try this:
console.log('aa|bb|cc'.split('|'));
console.log('aa\|aa|bb|cc|dd\|dd|ee'.split('|'));
['aa|aa', 'bb', 'cc', 'dd|dd', 'ee'] and I get this: ["aa", "aa", "bb", "cc", "dd", "dd", "ee"]
I assume that you want to skip splitting on escaped pipes. Use match instead:
console.log(
'aa\\|aa|bb|cc|dd\\|dd|ee'.match(/[^\\|]*(?:\\.[^\\|]*)*/g).filter(Boolean)
);Hi the Regex I created

What you need to do is concact the matches in an array
the code generated looks like this...
const regex = /(([^\\\|]+)\\?\|\2)|(\w+)/g;
const str = `aa\\|aa|bb|cc|dd\\|dd|ee`;
let m;
while ((m = regex.exec(str)) !== null) {
// This is necessary to avoid infinite loops with zero-width matches
if (m.index === regex.lastIndex) {
regex.lastIndex++;
}
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
});
}
Hope this help you.
match.
