Google apps script to grab data from webpage

问题

I had help making this script before that would pull the playercount off a website and log it into spreadsheets with a date and timestamp, this was:

function pullRuneScape() {
  var page = UrlFetchApp.fetch('http://runescape.com/title.ws').getContentText();
  var number = page.match(/PlayerCount.*>([0-9,]+)</)[1];
  SpreadsheetApp.getActive().getSheetByName('RuneScape').appendRow([new Date(), number]);
}

Basically in the webpage they list the amount of players and I wanted to log it every 5minutes or so, but they have another site I wanted to grab the number from too and I need some help.

It's at http://oldschool.runescape.com/slu

I wanted to grab the player count on that site, at the top, and log it just like I have here: https://docs.google.com/spreadsheet/ccc?key=0AjrAPynUEUl9dGtIZFY0TlRFUllVcWFyZDZ2c2o5Tnc#gid=0

Where column A is the date and time, and B is just the number of people, so the output would be like 1/1/2013 0:00:48 77,439

Thank you if you can help.

Read up on how to use regex. That will help you figure out what this code is doing. Please do not just copy the code that I have posted below. At Stack Overflow, we do not write code for you; we help you if something goes wrong.

var page = UrlFetchApp.fetch('http://oldschool.runescape.com/slu').getContentText();
var number = page.match(/There are currently ([0-9,]+)/)[1];
