How do i filter sitemap url with date modified to show urls for current date in app script?

var ss = SpreadsheetApp.getActiveSpreadsheet();

var sheet = ss.getSheetByName(‘Sheet1’);

function getLinks(){

var xml = UrlFetchApp.fetch(‘https://www.*********.com/job_listing-sitemap.xml’).getContentText();

var xmlObj = XmlService.parse(xml);

var root = xmlObj.getRootElement();

var ns = XmlService.getNamespace(‘http://www.sitemaps.org/schemas/sitemap/0.9’);

var links = root.getChildren();

var linksArr = [];

for(var i = 0; i < links.length; i++){

linksArr.push([links[i].getChildren()[0].getText()]);

}

sheet.getRange(2, 1, linksArr.length, 1).setValues(linksArr);
}
