如何在Google App Script中导入RSSfeed

function importRSSFeed() {
  var rssUrl = "https://example.com/rssfeed"; // 替换为要导入的RSS feed的URL
  
  var response = UrlFetchApp.fetch(rssUrl);
  var xml = response.getContentText();
  var document = XmlService.parse(xml);
  var root = document.getRootElement();
  
  var items = root.getChild("channel").getChildren("item");
  
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  
  for (var i = 0; i < items.length; i++) {
    var title = items[i].getChild("title").getText();
    var link = items[i].getChild("link").getText();
    var description = items[i].getChild("description").getText();
    
    sheet.getRange(i+1, 1).setValue(title);
    sheet.getRange(i+1, 2).setValue(link);
    sheet.getRange(i+1, 3).setValue(description);
  }
}
