使用Google App脚本解析HTML元素中的值? [英] Parse values from HTML element using Google App Script?

问题描述

我正在尝试在Google协作平台上按类解析HTML元素，我的代码是:

I am trying to parse HTML element by class on Google Sites, my code is:

function doGet(){

  var html = UrlFetchApp.fetch ('http://indicadoresdeldia.cl/').getContentText();
  var doc = XmlService.parse(html);
  var html = doc.getRootElement();
  var menu = getElementsByClassName(html, 'span3 utm')[0];
  var output = XmlService.getRawFormat().format(menu);
  return HtmlService.createHtmlOutput(output);

}

我在运行代码时出现了nexte错误消息ReferenceError:未定义"getElementsByClassName".

Ween i run the code appear the nexte error message ReferenceError: "getElementsByClassName" is not defined.

我正在尝试为下一页部署示例:https://sites.google.com/site/scriptsexamples/learn-by-example/parsing-html

i am trying to deploy the example for the next page: https://sites.google.com/site/scriptsexamples/learn-by-example/parsing-html

有什么想法吗?
