How should I put this XML object into a javascript dictionary?

XMLcoming in from get_objectives.php:

<container>
  <objective>
    <id>1</id>
    <type>thing</type>
    <name>banana</name>
    <date_added>2012-05-08 21:13:01</date_added>
    <released>2012-05-08 22:47:27</released>
  </objective>
  <objective>
    <id>2</id>
    <type>thing</type>
    <name>hammock</name>
    <date_added>2012-05-08 21:13:01</date_added>
    <released>2012-05-08 22:47:27</released>
  </objective>
</container>

The javascript that doesn’t work, that I”m trying to fix:

function updateObjectives(){
  $.post('scripts/get_objectives.php', {}, function(xml){
    $(xml).find("objective").each(function(i){
      objectives[i] = {}
      objectives[i]['id'] = $('id', xml).text()
      console.log("objectives["+i+"].id = "+objectives[i].id)
    })
  })
}

Based on the console output below, it appears that the $('id', xml).text() call that I am trying isn’t stuck inside the function handling the find(“objective”).each call:

objectives[0].id = 12
objectives[1].id = 12

    objectives[i]['id'] = $('id', this).text() does the trick!

    My problem was the ambigious syntax of the $() in the tutorial; $(query, context). Instead of looking for ('this > id', xml) which is looking for ‘this”s child named ‘id’ inside the full ‘xml’ file, (I already had found ‘this’!) so $('id', this) works because it is looking for ‘id’ inside ‘this’ (where ‘this’ is tags) I hope this helps someone!
