VB.net解析XML節點<value>

Question

我發現很多主題都顯示了解析XML文件的不同方法，但是它並沒有實現我想要的功能。 確實，我需要解析多個節點才能獲取更多數據：

<data_results data_size="64">
  <data>
    <row>
      <value>192.168.53.11|</value>
      <value>22951.2138889</value>
    </row>
    <row>
      <value>192.168.99.100|</value>
      <value>22749.0361111</value>
    </row>
  </data>
</data_results>

目的是取回具有相應字節數/秒的每個IP地址，並將它們放在表的新行中。

但是，如何從XML文檔中獲取這些信息？

謝謝你的支持。

干杯。

Answer 1

您可以嘗試以下方法：

Dim xml As XDOcument = XDocument.Parse(xmlString)
Dim listRows As List<XElement> = xml.Descendants("row").ToList()

For Each node As XElement in listRows
        Dim values As List<XElement> = node.Descendants("value").ToList()
        // first value is the IP
        Dim ip As String = values(0)
        // second value is the bytes
        Dim bytes As String = values(1)
Next

試圖將C＃代碼轉換為VB，可能在那里出現一兩個語法錯誤。

我終於設法得到自己的解決方案：

' Look for the tag "row" into the XML doc
Dim items4 = doc4.GetElementsByTagName("row")
Dim items5 = doc4.GetElementsByTagName("value")

    ' Parse all the XML tag with "row" and get the value for each expected attributes
    For Each item4 As System.Xml.XmlElement In items4

    ounter1 = 0

    For Each item5 As System.Xml.XmlElement In items5

        ' If it's the first value tag then it's the host IP address
        If counter1 = 0 Then

            ' Get the host IP address
            host = item4.ChildNodes(0).InnerText
            Console.WriteLine("host : " & host)

        ' If it's the second value tag then it's the number of Bytes/s
        ElseIf counter1 = 1 Then

            ' Get the host IP address
            bytesPerSec = item4.ChildNodes(1).InnerText
            Console.WriteLine("bytesPerSec : " & bytesPerSec)

        ' Otherwise it's an error
        Else

            ' Do nothing

        End If

            ' Increment counter
            counter1 = counter1 + 1

    Next

' Load the data into the target table
DataGridView10.Rows.Add(New String() {host, bytesPerSec})
