通过 Excel VBA 编辑 XML

打哈欠

我需要使用新值更新“简单”XML 文件并使用新名称保存。对于测试，我只尝试更新一个值。但是使用下面的代码我得到一个错误：

运行时错误“91”：未设置对象变量或块变量

VBA：

Sub XMLTest()
Dim myVar As String, pathToXML As String
Dim xmlDoc As Object, xmlRoot As Object
    Set xmlDoc = CreateObject("MSXML2.DOMDocument")
    pathToXML = "C:\Users\Path_to_XML\PJMeasurements.xml" '<--- Update path

    Call xmlDoc.Load(pathToXML)
    Set xmlRoot = xmlDoc.getElementsByTagName("ns0:MeasurementsSO").Item(0) '<--- Is this correct?
    myVar = "9999-9999999" '<--- Update value
    xmlRoot.SelectSingleNode("SalesOrderNo").Text = myVar

    Call xmlDoc.Save(pathToXML)
End Sub

这是 XML：

<ns0:MeasurementsSO xmlns:ns0="http://update.DocumentTypes.Schema.PJ Measurement.Xml">
  <SalesOrderNo>23482-4612310</SalesOrderNo>
  <Weight>83</Weight>
  <Volume>0,03</Volume>
  <Numberofcolli>1</Numberofcolli>
</ns0:MeasurementsSO>

您需要添加命名空间：

Sub XMLTest()
    Dim myVar As String, pathToXML As String
    Dim xmlDoc As Object, xmlNode As Object
    Set xmlDoc = CreateObject("MSXML2.DOMDocument")
    pathToXML = "C:\Temp\PJMeasurements.xml" '<--- Update path
    xmlDoc.setProperty "SelectionNamespaces", "xmlns:ns0='http://update.DocumentTypes.Schema.PJMeasurement.Xml'"
    Call xmlDoc.Load(pathToXML)
    Set xmlNode = xmlDoc.SelectSingleNode("/ns0:MeasurementsSO/SalesOrderNo")
    myVar = "9999-9999999" '<--- Update value
    xmlNode.Text = myVar
    Call xmlDoc.Save(pathToXML)
End Sub
