const regex = /(?<!\<a\shref)my(?!.*\<\/a\>)/gmi;
// Alternative syntax using RegExp constructor
// const regex = new RegExp('(?<!\\<a\\shref)my(?!.*\\<\\\/a\\>)', 'gmi')
const str = `This is a sample my text <a href="https://test.com">test my stuff</a> with my inside <a href="https://mytest.com">test me</a> brackets and my outside brackets oh my . <a href="https://test.com">test my stuff</a> not sure why my instances of my before the last lookahead doesnt work?
Intent: I have an FAQ that uses js to highlight words on the page by letter as you type. I need to ignore the HREF entries in the replace function as the injection of a class to highlight the typed letters/words replaced within the HREF messing up the link.
Incorrectly Ignoring position 18, 76, 141, 164
Correctly ignoring position 58, 104 and 201
Correctly finding position 227, 242`;
// Reset `lastIndex` if this regex is defined globally
// regex.lastIndex = 0;
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}`);
});
}
