我有一个如下所示的 XML 文档：

<?xml version="1.0" encoding="utf-8"?>
<entry xml:base="https://sps.utility.abc123.com/sites/xyz/_api/" xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:georss="http://www.georss.org/georss" xmlns:gml="http://www.opengis.net/gml" m:etag="&quot;5&quot;">

<link rel="edit" href="Web/Lists(guid'c920cb93-a31a-49a0-a4d6-ac1cb8fb0658')/Items(2)" />

<content type="application/xml">
<m:properties>
<d:Title>item 2 has a new value.</d:Title>
</m:properties>
</content>
</entry>

我想在<d:Title>节点上获取值，在这种情况下是item 2 has a new value.

当我使用以下内容时：

Private Function getFieldValueFromXml(xml As Variant, fieldName As String)

Dim node As IXMLDOMNode
Dim namespaceAndName As String
Dim domDoc as MSXML2.DomDocument60    

namespaceAndName = "d:" & fieldName
Set domDoc = New DOMDocument60
Set node = domDoc.SelectSingleNode(namespaceAndName)
getFieldValueFromXML = node.Text

End Function

该SelectSingleNode()调用引发此错误：

Reference to undeclared namespace prefix: 'd'.

如果我尝试首先设置节点，也会发生这种情况m，如下所示：

Set node = domDoc.SelectSingleNode("m:properties")

我怎样才能得到<d:Title>这里的内部文本？

我需要SelectionNamespaces在调用之前设置 DOM 文档的属性SelectSingleNode()，如下：

domDoc.SetProperty "SelectionNamespaces", "xmlns:d='http://schemas.microsoft.com/ado/2007/08/dataservices'"
