Ler XML ASP

Prezados,

boa noite. Estou precisando de um help!

possuo um script que retorna o seguinte XML:

	tenho o seguinte código em ASP:

<%

url_server = "http://127.0.0.1/xml.php?plugin=complete"

Set xmlhttp = Server.CreateObject("Microsoft.XMLHTTP")

Call xmlhttp.open("GET", url_server, false)

Call xmlhttp.send()

strRetorno = xmlhttp.responseText

Set oXmlDom = Server.CreateObject("Msxml2.DOMDocument.3.0")

oXmlDom.loadXML strRetorno

Set oNodes = oXmlDom.selectNodes("tns:phpsysinfo/FileSystem/Mount")

for each oNode in oNodes

response.write "Cache " & oNode.selectSingleNode("Percent").Text

next

Set oXmlDom = Nothing
%>

ao tentar trazer alguns valores, sempre me retorna o seguinte erro:

Erro de tempo de execução do Microsoft VBScript erro '800a01a8'

Objeto necessário: 'oNode.selectSingleNode(...)'

Preciso trazer os valores de:

CPU

Memory

HD

Alguém teria alguma dica de como consigo resolver?

Agradeço a atenção de todos.
