Question

我在选择xml中的某些节点时遇到问题。 XML看起来像这样：

<?xml version="1.0"?>
<GetConfigurationItems Error="False">
    <ConfigurationItem ID="14" Deleted="0">
        <AttachmentTypes DropDownType="14" Filter="%" Deleted="0">
            <AttachmentType ShortDesc="BOA_FIT" VersionNo="2" ID="1D8651D1-99E2-4D77-9BFF-1A667AA9398D">FIT</AttachmentType>
            <AttachmentType ShortDesc="BOA_LIMS" VersionNo="3" ID="F543938A-693F-457A-97AA-010065D0BA4E">Lims</AttachmentType>
            <AttachmentType ShortDesc="BOA_MICRO_PIC" VersionNo="1" ID="CC3FB18D-1E3F-400A-AD52-971A78A5517D">Microscope picture</AttachmentType>
        </AttachmentTypes>
    </ConfigurationItem>
</GetConfigurationItems>

现在我想保存ID属性，但要从某个值开始保存，因此一开始只需要进行FIT。我尝试了很多变化，我真的不知道我在做什么错.. :( 通过此代码，我可以从Web服务获取XML：

Webservice = "http://xxx.xxx.xxx/mm/rm/webservice/RMWS_ConfigurationRead.asmx?wsdl"

    functionName = "GetConfigurationItems"
    portName = "RMWS_ConfigurationReadSoap"
    Set DMIService = New DMIService
    Set oXML = CreateObject("msxml2.DOMDocument.6.0")
    oXML.LoadXML DMIService.execute(Webservice, functionName, portName, "<![CDATA[<GetConfigurationItems><ConfigurationItem ID=""" & ID & """ Deleted=""0""/></GetConfigurationItems>]]>")

这是连接字符串的一些尝试（不同的尝试是bsp1）：

    //GetConfigurationItems/ConfigurationItem[@ID="14"]/AttachmentTypes/AttachmentType[text="FIT"]/@ID
    //GetConfigurationItems/ConfigurationItem[@ID="14"]/AttachmentTypes[AttachmentType="FIT"]/@ID
    //GetConfigurationItems/ConfigurationItem[@ID="14"]/AttachmentTypes/[AttachmentType="FIT"]/@ID
    //GetConfigurationItems/ConfigurationItem[@ID="14"]/AttachmentTypes[AttachmentType[@Name="FIT"]/@ID
    //GetConfigurationItems/ConfigurationItem[@ID="14"]/AttachmentTypes[AttachmentType="FIT"]/@ID

ID = oXML.SelectSingleNode(bsp1).Text

我很确定这只是一个小小的失败，但是我现在尝试的时间太长了。如果有人可以帮助我，那就太好了。

Answer 1

这似乎有效。我正在从文件中读取XML样本。

Option Explicit
Public Sub GetNode()
    Dim xmlDoc      As MSXML2.DOMDocument60
    Set xmlDoc = New MSXML2.DOMDocument60
    xmlDoc.async = False
    xmlDoc.validateOnParse = True

    If Not xmlDoc.Load("C:\Users\User\Desktop\Testing.xml") Then
        MsgBox "Problem"
        Exit Sub
    End If
    Debug.Print xmlDoc.SelectSingleNode("//AttachmentType[text()='FIT']").Attributes.getNamedItem("ID").Text
End Sub

或

Debug.Print xmlDoc.SelectSingleNode("//*[text()='FIT']").Attributes.getNamedItem("ID").Text

这是我设法建立的：

Option Explicit
Sub TestMe()

    Dim xmlObj As Object
    Set xmlObj = CreateObject("MSXML2.DOMDocument")

    xmlObj.async = False
    xmlObj.validateOnParse = False
    xmlObj.Load (ThisWorkbook.Path & "\someXML.xml")

    Dim nodesThatMatter As Object
    Dim node            As Object
    Set nodesThatMatter = xmlObj.SelectNodes("//GetConfigurationItems")

    Dim level1 As Object
    Dim level2 As Object
    Dim level3 As Object
    Dim level4 As Object

    For Each level1 In nodesThatMatter
        For Each level2 In level1.ChildNodes
            For Each level3 In level2.ChildNodes
                For Each level4 In level3.ChildNodes
                    With level4
                        If .Attributes(0).Value Like "*FIT*" Then
                            Debug.Print "OK " & .Attributes(0).Value & .Attributes(2).Value
                        Else
                            Debug.Print "IGNORE " & .Attributes(0).Value
                        End If
                        Debug.Print .Text & vbCrLf
                    End With
                Next level4
            Next level3
        Next level2
    Next level1

End Sub

在即时窗口中显示此内容

OK BOA_FIT1D8651D1-99E2-4D77-9BFF-1A667AA9398D
FIT

IGNORE BOA_LIMS
Lims

IGNORE BOA_MICRO_PIC
Microscope picture

想法是尽可能多地使用Watches window，从而使用属性。我从上层//GetConfigurationItems开始，然后向下走，遍历每一个。
