[wengjw]

xml从<SCRIPT LANGUAGE=VBScript>
set ado_stream = CreateObject("ADODB.Stream")
set xml_dom = CreateObject("MSXML2.DOMDocument")
xml_dom.loadXML("<?xml version=""1.0"" ?> <root/>")
xml_dom.documentElement.setAttribute "xmlns:dt", "urn:schemas-microsoft-com:datatypes"
set file_body = xml_dom.createElement("file_body")
file_body.dataType = "bin.base64"
ado_stream.Type = 1
ado_stream.Open
ado_stream.LoadFromFile "c:\aaa.txt"
file_body.nodeTypedvalue = ado_stream.Read(-1)
ado_stream.Close()
xml_dom.documentElement.appendChild(file_body)
set file_name = xml_dom.createElement("file_name")
file_name.dataType = "string"
file_name.nodeTypedvalue = "aaaa"
xml_dom.documentElement.appendChild(file_name)
set xmlhttp = CreateObject("Microsoft.XMLHTTP")
