<script src="dist/xmp.iife.min.js"></script>

    let input = document.querySelector("input[type='file']");
    input.addEventListener("change", (e) => {
        let file = e.target.files[0];
        var reader = new FileReader();
        reader.onload = e => {
            let xmp = new XMP(e.target.result),
                raw = xmp.find(),
                parsed = xmp.parse();
            // do what you want with `raw` or `parsed` XMP

See demo.html for example.

As ES6 Module

import XMP from "xmp-js";

        console.error("Error while reading the file", err);
    }
