So you want to manipulate DOM serverside before sending it to the client? 因此，您想在将DOM服务器端发送给客户端之前对其进行操作？ If so, take a look at this (using "jsdom"): http://marksoper.me/Server-side-DOM-manipulation-in-Nodejs-with-JSDOM-JQuery-and-Mustache-Templates-April-25-2011.html 如果是这样，请看一下（使用“ jsdom”）： http ://marksoper.me/Server-side-DOM-manipulation-in-Nodejs-with-JSDOM-JQuery-and-Mustache-Templates-April-25 -2011.html

@MattiasHognas didn't accept my edit, so going off his link this is what I am thinking was meant: @MattiasHognas不接受我的编辑，因此断开他的链接，这就是我在想的意思：
require.paths.unshift('/usr/local/lib/node_modules');
var fs = require('fs'),
jsdom = require('jsdom');
var read_and_edit_me = fs.readFileSync('read_and_edit_me.html','utf-8');
var document = jsdom.jsdom(read_and_edit_me);
Then document should be able to used as in my question's snippet? 然后document应该可以用作我的问题的摘要吗？
