var oHtml = document.documentElement;
var oDoc = oHtml.ownerDocument;
var oHead = oHtml.childNodes[0];
var oBody = oHead.nextSibling;
var oTitle = oHead.firstChild;
var oP1 = oBody.firstChild;
var oP2 = oP1.nextSibling;
var oP3 = oBody.lastChild;
var oA = oP1.firstChild;
var oAText = oA.firstChild;
var aNodes = [oDoc, oHtml, oHead, oTitle, oBody, oP1,oA, oAText];
var ah = "第三段";
var sMsg = "<table align=\"center\" border=\"1\"" +
"cellspacing=\"0\" cellpadding=\"3\" width=\"443\">";
sMsg += "<tr><th>节点名称</th><th>节点值</th><th>节点类型</th></tr>";
for(var i = 0; i < aNodes.length; i++)
{
sMsg += "<tr><td>" + aNodes[i].nodeName;
sMsg += "</td><td>" + aNodes[i].nodeValue;
sMsg += "</td><td>" + aNodes[i].nodeType + "</td></tr>";
}
sMsg += "<table>\n";
oP2.innerHTML = sMsg;
oP3.innerHTML =ah;
