如何使用VBA到Excel读取XML属性？

Question

这是我的代码..

   <?xml version="1.0" ?> 
   <DTS:Executable xmlns:DTS="www.microsoft.com/abc" DTS:ExecutableType="xyz">
       <DTS:Property DTS:Name="PackageFormatVersion">3</DTS:Property> 
       <DTS:Property DTS:Name="VersionComments" /> 
       <DTS:Property DTS:Name="CreatorName">FirstUser</DTS:Property> 
       <DTS:Property DTS:Name="CreatorComputerName">MySystem</DTS:Property>
   </DTS:Executable>

在这里,我能够使用"abc.baseName"读取Elements,使用"abc.Text"读取其值.它给了我结果

物业3物业
物业FirstUser

在这里我如何读取"PackageFormatVersion"为3？也就是说,我知道一些价值是3,但那个价值是什么我怎么知道？

我的意思是我必须选择我想要阅读的属性.

请参阅元素的.Text属性或.nodeTypeValue属性:

Sub TestXML()
Dim xmlDoc As Object 'Or enable reference to Microsoft XML 6.0 and use: MSXML2.DOMDocument
Dim elements As Object
Dim el As Variant
Dim xml$
xml = "<?xml version=""1.0"" ?>"
xml = xml & "<DTS:Executable xmlns:DTS=""www.microsoft.com/abc"" DTS:ExecutableType=""xyz"">"
xml = xml & "<DTS:Property DTS:Name=""PackageFormatVersion"">3</DTS:Property>"
xml = xml & "<DTS:Property DTS:Name=""VersionComments"" />"
xml = xml & "<DTS:Property DTS:Name=""CreatorName"">FirstUser</DTS:Property>"
xml = xml & "<DTS:Property DTS:Name=""CreatorComputerName"">MySystem</DTS:Property>"
xml = xml & "</DTS:Executable>"

Set xmlDoc = CreateObject("MSXML2.DOMDocument")
'## Use the LoadXML method to load a known XML string
xmlDoc.LoadXML xml
'## OR use the Load method to load xml string from a file location:
'xmlDoc.Load "C:\my_xml_filename.xml"

'## Get the elements matching the tag:
Set elements = xmlDoc.getElementsByTagName("DTS:Property")
'## Iterate over the elements and print their Text property
For Each el In elements
    Debug.Print el.Text
    '## Alternatively:
    'Debug.Print el.nodeTypeValue
Next

End Sub

我知道有些价值是3但是那个价值是什么我怎么知道？

您可以在"本地"窗口中查看对象,并检查其属性:

这是一个替代方案,对我而言似乎比使用它GetElementsByTagName更笨拙但如果你需要遍历文档,你可以使用这样的东西:

Sub TestXML2()
Dim xmlDoc As MSXML2.DOMDocument
Dim xmlNodes As MSXML2.IXMLDOMNodeList
Dim xNode As MSXML2.IXMLDOMNode
Dim cNode As MSXML2.IXMLDOMNode
Dim el As Variant
Dim xml$
xml = "<?xml version=""1.0"" ?>"
xml = xml & "<DTS:Executable xmlns:DTS=""www.microsoft.com/abc"" DTS:ExecutableType=""xyz"">"
xml = xml & "<DTS:Property DTS:Name=""PackageFormatVersion"">3</DTS:Property>"
xml = xml & "<DTS:Property DTS:Name=""VersionComments"" />"
xml = xml & "<DTS:Property DTS:Name=""CreatorName"">FirstUser</DTS:Property>"
xml = xml & "<DTS:Property DTS:Name=""CreatorComputerName"">MySystem</DTS:Property>"
xml = xml & "</DTS:Executable>"

Set xmlDoc = CreateObject("MSXML2.DOMDocument")
'## Use the LoadXML method to load a known XML string
xmlDoc.LoadXML xml
'## OR use the Load method to load xml string from a file location:
'xmlDoc.Load "C:\my_xml_filename.xml"

'## Get the elements matching the tag:
Set xmlNodes = xmlDoc.ChildNodes
'## Iterate over the elements and print their Text property
For Each xNode In xmlDoc.ChildNodes
    If xNode.NodeType = 1 Then  ' only look at type=NODE_ELEMENT
        For Each cNode In xNode.ChildNodes
            Debug.Print cNode.nodeTypedValue
            Debug.Print cNode.Text
        Next
    End If
Next

End Sub
