var myValue=myxpath.attributes()

var myContents=xml_Contents(myxpath,myValue);

alert(myContents)

function xml_Contents(mxl,mycnt)

{

    var myCont=[];

    try

    {

        var myxm=XML(mxl);

        if(myxm.contains(mycnt)==true)

        {

            myxm.descendants();

       return myCont;
