The node list returned by .SelectNodes() is a collection with a .length property that can be traversed using a zero-based integer index:

.SelectNodes()返回的节点列表是一个具有.length属性的集合，可以使用从零开始的整数索引遍历该集合:

Option Explicit

Dim oFS    : Set oFS  = CreateObject("Scripting.FileSystemObject")
Dim sFSpec : sFSpec   = oFS.GetAbsolutePathName("..\data\33921005.xml")
Dim oXML   : Set oXML = CreateObject("Msxml2.DOMDocument.6.0")
oXML.load sFSpec
If 0 = oXML.parseError Then
   Dim ndlName : Set ndlName = oXML.selectNodes("/Envelope/Body/Request/individual/hasName/*")
   Dim ndName
   For Each ndName In ndlName
       WScript.Echo ndName.tagName
   Next
   Dim iNd
   For iNd = 0 To ndlName.length - 1
       WScript.Echo iNd, ndlName(iNd).tagName
   Next
Else
   WScript.Echo oXML.parseError.reason
End If

output:

输出:

cscript 36053711.vbs
firstName
lastName
0 firstName
1 lastName

Following on from my initial comment.

根据我最初的评论。

The selectNodes() method returns a IXMLDOMNodeList object which is a NodeList collection.

selectNodes()方法返回一个IXMLDOMNodeList对象，它是一个NodeList集合。

As with any collection it contains members common to collection objects

与任何集合一样，它包含集合对象共有的成员

Properties

属性

• length - Number of Nodes in the collection
• 长度-集合中节点的数量

Methods

方法

• item - Access to individual Nodes within the collection
• 项目-对集合中各个节点的访问

_{For full list of member properties and methods see IXMLDOMNodeList Members}

有关成员属性和方法的完整列表，请参阅IXMLDOMNodeList成员

There should be no logical reason why you need to change your For Each to a For loop as you can just use the length property to retrieve the number of Nodes in the collection.

应该没有逻辑理由需要将For Each改为For循环，因为您可以使用length属性来检索集合中的节点数量。

Option Explicit

Dim node, nodes, li, i, sXPath, NumberOfNodes
Set nodes = objMSXML.selectNodes(sXPath)
'Retrieve number of Nodes
NumberOfNodes = nodes.length
For Each node In nodes                   
    Set li = document.createElement("li")
    li.innerText = i & " " & node.text
    ul.appendChild li
    i = i +1
Next
