推荐答案
确定要使用过时的程序ID Microsoft.XMLHTTP吗?这些天以来，MSXML 3和MSXML 6都是OS各自支持的Service Pack的一部分，自Windows XP以来便已提供任何支持.
至于使用XPath和MSXML 3，下面是一个示例:
Are you sure you need to use the antiquated program id Microsoft.XMLHTTP? These days both MSXML 3 as well as MSXML 6 are part of the OS respectively supported service packs with anything since Windows XP.
As for using XPath and MSXML 3, here is an example:
Dim doc
Set doc = CreateObject("Msxml2.DOMDocument.3.0")
doc.validateOnParse = False
doc.resolveExternals = False
If doc.load("file.xml") Then
doc.setProperty "SelectionLanguage", "XPath"
doc.setProperty "SelectionNamespaces", "xmlns:xhtml='http://www.w3.org/1999/xhtml'"
For Each link In doc.selectNodes("//xhtml:a")
WScript.Echo(link.getAttribute("href") & ": " & link.text)
Next
Else
WScript.Echo(doc.parseError.reason)
End If
