# loadXML

#### loadXML(url, headers) → Promise.<XMLDocument>
Core/loadXML.js 35

  Asynchronously loads the given URL as XML. Returns a promise that will resolve to an XML Document once loaded, or reject if the URL failed to load. The data is loaded using XMLHttpRequest, which means that in order to make requests to another origin, the server must have Cross-Origin Resource Sharing (CORS) headers enabled.

  Name | Type | Description
  --- | --- | ---
  `url` | String | Promise.<String> | The URL to request, or a promise for the URL.
  `headers` | Object | optional HTTP headers to send with the request.

  ##### Returns:

  a promise that will resolve to the requested data when loaded.

  ##### Example:

      // load XML from a URL, setting a custom header
      Cesium.loadXML('http://someUrl.com/someXML.xml', {
        'X-Custom-Header' : 'some value'
      }).then(function(document) {
          // Do something with the document
      }).otherwise(function(error) {
          // an error occurred
      });
