Load XML by ID - Flash CS3, AS2

programming flash
1

I have to load a lot of information for 25 movies which load into a main SWF. And all the contents are loaded from a XML file.
This comes from a client’s file already programmed in AS2 so I cannot use AS3 to load the XML which is a lot easier.

This is an example of my xml structure:
<root>
<button>
<btn1>button 1</btn1>
<btn2>button 2</btn2>
</button>

&lt;movies&gt;
	&lt;movie id="slide1"&gt;
		&lt;title&gt;Slide n1&lt;/title&gt;
		&lt;text&gt;Conteúdo 1&lt;/text&gt;
	&lt;/movie&gt;

	&lt; movie id="slide2"&gt;
		&lt;title&gt;Slide n2&lt;/title&gt;
		&lt;text&gt;Conteúdo 2&lt;/text&gt;
                    &lt;image id="one"&gt;bicycle.jpg&lt;/image&gt;
	&lt;/movie &gt;
&lt; movies&gt;

</root>

There are about 25 slide nodes each with an ID. And each with a title, more than one text to load and some also have images.
Is there a way that I call each slide by its ID, instead of having to write the entire code for the nodes?
Right now I am using this AS2

my_xml = new XML();
my_xml.ignoreWhite = true;
my_xml.onLoad = function(sucess) {
if (sucess) {
trace(my_xml);
}
};
// Load up the XML file into Flash
my_xml.load(‘modulo1.xml’);

// Load info for the buttons
btn1 = my_xml.firstChild.firstChild.childNodes[0].firstChild;
btn2 = my_xml.firstChild.firstChild.childNodes[1].firstChild;
// Slide One
****lide1 = my_xml.firstChild.firstChild.nextSibling.childNodes[0].firstChild.childNodes;
txtslide1 =my_xml.firstChild.firstChild.nextSibling.childNodes[0].firstChild.nextSibling.childNodes;

Coding it this way I will probably get lost along the way.
If I could get the slides by ID it would be a lot easier and faster to code.
