Mass select authors by name in Wordpress import

gistfile1.txt

var a = $('ol#authors li strong')
a.each(function(index, el) {
	let b = $(el).text().split(' (')[0]
	let c = $(el).closest('li')
	let d = $(c[0]).find('div select option:contains("' + b + '")').val();
	$(c[0]).find('div select').val(d)
});

OR, add them as new values:

var a = $('ol#authors li strong')
a.each(function(index, el) {
	let b = $(el).text().split(' (')[0]
	let c = $(el).closest('li')
	$(c[0]).find('div input').val(b)
});
