xml - 使用 VBA 将 XML 数据导入 Excel，selectnodes 不起作用(不返回任何内容)

Question

我有以下 XML

<cqresponse xmlns="http://ibm.com/rational/cqweb/v7.1">
<rows>
    <row>
        <id>
            <![CDATA[ ABC00082474 ]]>
        </id>
        <Short_Desc>
            <![CDATA[
            Some Description 1
            ]]>
        </Short_Desc>
        <State>
            <![CDATA[ Some State 1 ]]>
        </State>
     </row>
     <row>
        <id>
            <![CDATA[ ABC00082475 ]]>
        </id>
        <Short_Desc>
            <![CDATA[
            Some Description 2
            ]]>
        </Short_Desc>
        <State>
            <![CDATA[ Some State 2 ]]>
        </State>
    </row>
</rows>
</cqresponse>

我想使用 VB 脚本将其导入 Excel。我有以下代码，但 SelectNodes 没有返回任何内容。它只是返回任何内容

Sub Test()
    Dim nodeList As IXMLDOMNodeList
    Dim nodeRow As IXMLDOMNode
    Dim nodeCell As IXMLDOMNode
    Dim rowCount As Integer
    Dim cellCount As Integer
    Dim rowRange As Range
    Dim cellRange As Range
    Dim sheet As Worksheet
    Dim xpathToExtractRow As String
    Dim dom As DOMDocument60

    xpathToExtractRow = "/cqresponse/rows/row"

    Set dom = New DOMDocument60
    dom.Load ("C:\ABC.xml") ' this file contains the same xml data as mentioned above
    Set sheet = ActiveSheet
    Set nodeList = dom.SelectNodes(xpathToExtractRow)

    rowCount = 0
    For Each nodeRow In nodeList
        rowCount = rowCount + 1
        cellCount = 0
        For Each nodeCell In nodeRow.ChildNodes
            cellCount = cellCount + 1
            Set cellRange = sheet.Cells(rowCount, cellCount)
            cellRange.Value = nodeCell.Text
        Next nodeCell
    Next nodeRow
End Sub

这有什么问题吗？还是我需要采取不同的方法？

XML 解析中经常犯的错误是根中未声明的命名空间。因此，您必须在解析文档期间分配命名空间前缀，并在 XPath 表达式中使用此类前缀。下面，分配了doc:

...
Dim xpathToExtractRow As String, XMLNamespaces As String
Dim dom As DOMDocument60

xpathToExtractRow = "/doc:cqresponse/doc:rows/doc:row"
XMLNamespaces = "xmlns:doc='http://ibm.com/rational/cqweb/v7.1'"

Set dom = New DOMDocument60
dom.Load ("C:\ABC.xml")
dom.setProperty "SelectionNamespaces", XMLNamespaces
...
