Calling XML using Javascript

Hi all,

I have 5 different XML files with the similar structure as below, first
I wanted to merge them and then perform my display actions, tried
various ways, but it wasn't working out as intended and instead
complicating the whole thing.

So, now I have created radio buttons, on one of the 5 xml sheets and by
default the first is selected, and if any other radio button is selected
I have a javascript function for the onclick event of the radio group
that is expected to call the xml file. Now the question is, is it even
possible to do so and if so then how do I do it?

The node names all match in all the xml files. Below is an example of
one XML I have. Does anyone know how to call an xml from javascript to
one xml or directly get data from the xmls to display in one web page?

Thank you all for your help in advance..

<?xml-stylesheet type="text/xsl" href="todropdown.xsl"?>

<tr>
	  <input type="radio" name="ProjType" value="CMM"
onclick="javascript:selectProject(this)" > CMM</input>
	  <input type="radio" name="ProjType" value="CRR"
onclick="javascript:selectProject(this)" > CRR </input>
	  <input type="radio" name="ProjType" value="MIS"
onclick="javascript:selectProject(this)" > MIS </input>
	  <input type="radio" name="ProjType" value="MMS"
onclick="javascript:selectProject(this)" > MMS </input>
	  <input type="radio" name="ProjType" value="MPIM"
onclick="javascript:selectProject(this)" > MPIM </input>

	  <input id="ProjTypeButton" style="font-family:times"
name="ProjTypeButton" type ="button" value="Select Project!"/>

          <hr align="center" width="100%"></hr>
      </tr>

I need help with writing the function!

function selectProject(proj)
{
	alert ("Selected Project is " + proj.value);

//<xsl:template match="/">
//<xsl:apply-templates select="//funcdef |
document("path/funcdefs2.xml")//funcdef |
//document("path/funcdefs3.xml")//funcdef |
document("path/funcdefs4.xml")//funcdef |
//document("path/funcdefs5.xml")//funcdef"/>
//</xsl:template>

}

Thanks!
