Get List of jQuery UI themes - from an URL (same-origin-policy)

Question

Does anyone know a way to get list of jQuery themes from http://jquery-ui.googlecode.com/svn/tags/1.8.23/themes/ ?

I am creating simple webpage with themes roller where the user can switch themes dynamically.

Working fiddle - Click on Themes on Right top corner and select a new theme.

Right now the list is hard coded as below,

<div id="theme-list">    
   <ul>
      <li class="themes-el ui-state-highlight" data-theme="cupertino">cupertino</li>
      <li class="themes-el" data-theme="hot-sneaks">hot-sneaks</li>
      <li class="themes-el" data-theme="smoothness">smoothness</li>
      <li class="themes-el" data-theme="pepper-grinder">pepper-grinder</li>
      <li class="themes-el" data-theme="ui-lightness">ui-lightness</li>
      <li class="themes-el" data-theme="ui-darkness">ui-darkness</li>
      <!-- and more -->
   </ul>    
</div>

Is there a way to get this list of themes from URL http://jquery-ui.googlecode.com/svn/tags/1.8.23/themes/? (crossDomain: http://www.w3.org/TR/cors/#access-control-allow-origin-response-hea)

Tried, but failed with below code..

$.ajax({
    url: 'http://jquery-ui.googlecode.com/svn/tags/1.8.23/themes/',
    dataType: 'text',
    beforeSend: function ( xhr ) {
        xhr.setRequestHeader("Access-Control-Allow-Origin", 'http://jquery-ui.googlecode.com');
        xhr.setRequestHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");
    },
    crossDomain: true,
    success: function (data) {
        alert(data);
    }, 
    error: function (jqXHR, textStatus, errorThrown) {
        alert(errorThrown + ' ' + textStatus + ' ' + jqXHR.responseText);
    }
});

It feels like I am missing a lot here.. any insight would really help.

I found this service from yahoo(YQL) and this Cross-domain requests with jQuery plugin that uses YQL to fetch cross domain content.

DEMO: http://jsfiddle.net/SXHrB/4/

The below code simply fetched me the whole page which I parsed to get the required content.

$.ajax({
    url: 'http://jquery-ui.googlecode.com/svn/tags/1.8.23/themes/',
    type: 'GET',
    success: function(data) {
        alert(data.responseText.substring(data.responseText.indexOf('<ul>'), data.responseText.lastIndexOf('</ul>') + 4));
    }
});
