I am trying to write a widget which uses a static XML file which would be bundled with the widget. I want the XML file to hold the data for items in a popup menu in the widget. So basically when the widget starts it needs to read the xml file to get the options in the menu. I've been trying to figure out how to do this in _javascript_ and have been striking out.

Since you're abstracting the data out, why not just put it into a _javascript_ file as an array that you iterate through? Something along this train of thought should work nicely:

You create a file for the values you're abstracting out (say, Values.js). In it is an array with the needed values:

var Values = [

"Value 1",

...

"Value n",

];

Then, in your _javascript_ file (say, Widget.js) you include a setup() function that loads the values:

function setup()

{

...

var menu = document.getElementById("myMenu");

var c = Values.length;

for ( var i = 0; i < c; i++ ) {

menu.add(Values[i]);

}

...

}

To tie it all together you include both _javascript_ files into your HTML and call setup() when your widget's body loads:

<html>

<head>

...

...

</head>

<body >

...

...

</body>

</html>
