Parsing XML Data that I receive from UrlFetch - google-apps-script

Question

I want to parse the data I get from UrlFetch into a spreadsheet, but all I'm getting is undefined can someone show me what i'm doing wrong
The xml is at the address https://dl.dropbox.com/u/11787731/Minecraft/bans.xml
function runevery15mins() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("MC Bans");
sheet.clearContents();
var banURL = "https://dl.dropbox.com/u/11787731/Minecraft/bans.xml";
var banXML = UrlFetchApp.fetch(banURL).getContentText();
var banDOC = Xml.parse(banXML, false);
var mcuser = banDOC.bans;
var x = 0;
for(var c=0; c>mcuser.length;c++){
var name = mcuser.getElement("username")[c].getText();
var date = mcuser.getElement("date")[c].getText();
var reason = mcuser.getElement("reason")[c].getText();
var duration = mcuser.getElement("duration")[c].getText();
}
sheet.appendRow([name, date, reason, duration]);
}

Answer 1

You have some small errors in your code.
For example, the second argument in the for loop needs to be c<mcuser.length.
Using the Xml service documentation, this worked for me
function runevery15mins() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("MC Bans");
sheet.clearContents();
var banURL = "https://dl.dropbox.com/u/11787731/Minecraft/bans.xml";
var banXML = UrlFetchApp.fetch(banURL).getContentText();
var banDOC = Xml.parse(banXML, false);
// Get all the child nodes from the document element that are 'user' nodes
var mcusers = banDOC.getElement().getElements('user');
for(var c=0; c<mcusers.length;c++){
var user = mcusers[c];
var name = user.getElement('username').getText();
var date = user.getElement('date').getText();
var reason = user.getElement('reason').getText();
var duration = user.getElement('duration').getText();
sheet.appendRow([name, date, reason, duration]);
}
}
Note for example that the sheet.appendRow line is INSIDE the loop, not outside as you had it before. I also deleted the X variable, since I didn't see any purpose for it.
I also created a user variable, which is an XmlElement, to make it easier to understand how to get the different contents of each node.

You were almost there.
Looks like there was another array you needed to drill down into. Also, your call back to the spreadsheet should be in the loop. Try this:
...
var mcuser = banDOC.bans.user;
for(var i in mcuser){
var name = mcuser[i].getElement("username").getText();
var date = mcuser[i].getElement("date").getText();
var reason = mcuser[i].getElement("reason").getText();
var duration = mcuser[i].getElement("duration").getText();
sheet.appendRow([name, date, reason, duration])
}
