'<document>' + '<loadingTemplate>' + '<activityIndicator>' + '<text>Hello World!</text>' + '</activityIndicator>' + '</loadingTemplate>' + '</document>'; var templateParser = new DOMParser(); var parsedTemplate = templateParser.parseFromString(template, "application/xml"); navigationDocument.pushDocument(parsedTemplate); }
