xastscript

xastscript is a great way to safely generate XML from within JavaScript - it provides a sort of 'Domain Specific Language' for building XML trees, and then you can encode that into XML using xast-util-to-xml.

For example, we at Val Town use xastscript and these utilities to generate our sitemap.xml file for Google to discover vals.

export let xastscriptExample = (async () => {
const { x } = await import("npm:xastscript");
const { toXml } = await import("npm:xast-util-to-xml@4");
// Create a DOM tree
const tree = x("album", { id: 123 }, [
x("name", "Born in the U.S.A."),
x("artist", "Bruce Springsteen"),
x("releasedate", "1984-04-06"),
]);
// Encode it as an HTML string
return toXml(tree);
})();
