如何使用 VBA 从 XML 中读取所有属性? [英] How I can read all Attributes from a XML with VBA?
问题描述
我从 Web 服务获得了一个 XML.我将其声明为DOMDocument".这是我的 XML.现在我想读取所有名为ZIP"的属性.
I got from a Webservice an XML. I declared it as a "DOMDocument". This is my XML. Now I want to read all Attributes named "ZIP".
<?xml version="1.0" encoding="utf-8" ?>
<Location>
<Cities>
<City ZIP="8355">Aadorf</City>
<City ZIP="5000">Aarau</City>
<City ZIP="5004">Aarau</City>
<City ZIP="5032">Aarau Rohr</City>
<City ZIP="3270">Aarberg</City>
<City ZIP="4663">Aarburg</City>
<City ZIP="4912">Aarwangen</City>
<City ZIP="8607">Aathal-Seegräben</City>
<City ZIP="8522">Aawangen</City>
<City ZIP="1657">Abländschen</City>
<City ZIP="5646">Abtwil AG</City>
<City ZIP="9030">Abtwil SG</City>
</Cities>
<Location>
随着...
Private Sub Workbook_Open()
Dim i As Integer
Dim NumberOfElements As Integer
Dim City As String
Dim xmlUrl As String
Dim xmlDoc As New DOMDocument
xmlUrl = "http://localhost:62231/dataHandling.asmx/GetAllCities"
xmlDoc.async = False
If xmlDoc.Load(xmlUrl) = False Then
MsgBox ("XML LOAD ERROR")
Else
NumberOfElements = xmlDoc.getElementsByTagName("City").Length
For i = 0 To NumberOfElements - 1
City = xmlDoc.SelectSingleNode("//Cities/City").Attributes.getNamedItem("ZIP").Text
City = City & " " & xmlDoc.getElementsByTagName("City").Item(i).Text
Tabelle2.Cells(i + 3, 1).Value = City
Next i
End If
End Sub
我从元素城市"中获得了所有的内文.但每次都是相同的属性8355".
I get all Innertextes from the Elements "City". But everytime the same Attribute "8355".
City = xmlDoc.SelectSingleNode("//Cities/City").Attributes.getNamedItem("ZIP").Text
这一行应该有所不同,但我不知道如何循环抛出整个 XML 以读取每个属性.
This line should be different, but I don't know how I can loop threw the whole XML to read every single Attrbute.
推荐答案
xmlDoc.SelectSingleNode("//Cities/City")
总是选择第一个节点.它不能每次都神奇地选择下一个节点,它必须为此读取您的想法.
xmlDoc.SelectSingleNode("//Cities/City")
always selects the first node. It cannot magically select the next node every time, it would have to read your mind for that.
Private Sub Workbook_Open()
Dim City As String
Dim xmlUrl As String
Dim xmlDoc As New DOMDocument
Dim n As IXMLDOMNode
Dim i As Long
xmlUrl = "http://localhost:62231/dataHandling.asmx/GetAllCities"
xmlDoc.async = False
If Not xmlDoc.Load(xmlUrl) Then
MsgBox "XML LOAD ERROR"
Else
For Each n In xmlDoc.selectNodes("//Cities/City")
City = n.Attributes.getNamedItem("ZIP").Text
City = City & " " & n.Text
Tabelle2.Cells(i + 3, 1).Value = City
i = i + 1
Next
End If
End Sub
