DOM Parser not working in IDJS script

Hi All,

I'm developing the UXP scripts for InDesign. While reading the HTML file, we use a DOM Parser to read the HTML file.

our UXP is not supporting to read the DOM parser. Kindly any one resolve this and will appreciate. 

//======================================

const file = await ufs.getFileForOpening({mode: uxpfs.modes.readWrite, type: "file"});

const text = await file.read({format: formats.utf8});

if (window.DOMParser) {
const parser = new DOMParser();

var manifest = parser.parseFromString(text, "text/xml");

}

//==================================

Thanks & Regards,
