Parse XML with Google Apps Script

Question

It's hard for me to parse the XML from the boardgamegeek request so that I can populate the Google worksheet with data. Here is an example of bgg xml:

<boardgames termsofuse="http://boardgamegeek.com/xmlapi/termsofuse">
  <boardgame objectid="423">
    <yearpublished>1995</yearpublished>
    <minplayers>3</minplayers>
    <maxplayers>6</maxplayers>
    <playingtime>300</playingtime>
    <name primary="true" sortindex="1">1856</name>
  </boardgame>
</boardgames>

And here is the Google Apps Script that I wrote to analyze it:

//get the data from boardgamegeek
  var url = 'http://www.boardgamegeek.com/xmlapi/boardgame/' + bggCode;
  var bggXml = UrlFetchApp.fetch(url).getContentText();

  var document = XmlService.parse(bggXml);
  var root = document.getRootElement();     
  var entries = new Array();
  entries = root.getChildren('boardgame');

  for (var x = 0; x < entries.length; i++) {
    var name = entries[x].getAttribute('name').getValue();
    var yearpublished = entries[x].getAttribute('yearpublished').getValue();
    var minplayers = entries[x].getAttribute('minplayers').getValue();
    var maxplayers = entries[x].getAttribute('maxplayers').getValue();
  }
  //SpreadsheetApp.getActiveSheet().getRange(i+1,7).setValue(yearpublished);
  Logger.log(entries);

I am currently getting a for-loop error caused by NULL entries. If I comment on the loop and register what bggXml looks like, it looks the same as in the example above. However, writing the variables further, I get the following:

document => [Document:  No DOCTYPE declaration, Root is [Element: <boardgames/>]]
root => [Element: <boardgames/>]
entries =>  [[Element: <boardgame/>]]
entries[2] => undefined

Since bggXml looks exactly as I would expect, but the document does not work, I assume the problem is parsing?

, . xml :

var yearpublished = root.getChild('boardgame').getChild('yearpublished').getText();

, . , .

//get the data from boardgamegeek
  var url = 'http://www.boardgamegeek.com/xmlapi/boardgame/' + bggCode;
  var bggXml = UrlFetchApp.fetch(url).getContentText();

  var document = XmlService.parse(bggXml);
  var root = document.getRootElement();

  //set variables to data from bgg
  var yearpublished = root.getChild('boardgame').getChild('yearpublished').getText();
  var minplayers = root.getChild('boardgame').getChild('minplayers').getText();
  var maxplayers = root.getChild('boardgame').getChild('maxplayers').getText();
  var playingtime = root.getChild('boardgame').getChild('playingtime').getText();
  var name = root.getChild('boardgame').getChild('name').getText();

  //populate sheet with variable data
  SpreadsheetApp.getActiveSheet().getRange(i+1,1).setValue(name);
  SpreadsheetApp.getActiveSheet().getRange(i+1,4).setValue(minplayers);
  SpreadsheetApp.getActiveSheet().getRange(i+1,5).setValue(maxplayers);
  SpreadsheetApp.getActiveSheet().getRange(i+1,5).setValue(playingtime);
  SpreadsheetApp.getActiveSheet().getRange(i+1,7).setValue(yearpublished);
