Accessing XML data with jQuery?

Question

Say I have this XML, which repeats itself:

<sample>
    <org.postgis.Point>
     <dimension>2</dimension>
     <haveMeasure>false</haveMeasure>
     <type>1</type>
     <srid>4326</srid>
     <x>-73.43975830078125</x>
     <y>42.0513801574707</y>
     <z>0.0</z>
     <m>0.0</m>
    </org.postgis.Point>
<sample>

And am using jQuery to try to get the x and y coordinates out of it. How do I do that?

   $(xml).find('sample').each(function(){
      $(this).find('org.postgis.Point').each(function(){
         var x = $(this).find('x').text();

Is this the right idea? Is there a less verbose way to get inside nested tags?

First of all, you'll need to escape the .s, because in CSS selectors, they represent classes. Next, you can drop a level of eaches by using the descendant combinator, :

$(xml).find('sample org\\.postgis\\.Point').each(function() {
     var x = $(this).find('x').text();

And of course, if there's only one org.postgis.Point:

var x = $(xml).find('sample org\\.postgis\\.Point x').text();
