推荐答案

我把你的代码片段放在这里并稍作修改.

I am having your snippet here and modified it slightly.

对我来说它有效，它甚至可以访问隐藏节点的内容并将其添加到结果页面.(Firefox 35.0 浏览器/Debian)

For me it works, it accesses the content even of the hidden node and adds this to the result page. (Firefox 35.0 Browser / Debian)

您是否偶然将显示的 HTML 结果误解为日志输出?

Were you by chance misinterpreting the displayed HTML result as log output?

function getElementByXpath (path) {
  return document.evaluate(path, document, null,
    XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
}

document.write("<br/>1: [" + 
  getElementByXpath("//html/body/div[1]").innerHTML + "]");
document.write("<br/>2: [" + 
  getElementByXpath("//html/body/div[2]").innerHTML + "]");

<div style="display:none;">First Div</div>
<div>Second Div</div>
