Answer 1

var xmlDom = new ActiveXObject("Msxml2.DOMDocument");
xmlDom.async = false;
xmlDom.loadXML("d:\\db\\type.xml")
var items1 = xmlDom.selectNodes("//NewDataSet/cube_id"); 
var items2 = xmlDom.selectNodes("//NewDataSet/table_dimension"); 
var items3 = xmlDom.selectNodes("//NewDataSet/dimension"); 
var itemsLength=items1.length;
for (i=0;i<itemsLength;i++)
{
if (items2[i].text=="a")
{
x=items2[i].text;
}else ...
}

Answer 2

var name = items.childNodes[i].attributes["Name"].value;
