[英]How to copy complete node from xml file and create multiple node by changing names of elements in Vb.net
我想從xml文件復制完整的節點,並使用該節點創建新的xml文件。
假設節點由對象組成,例如button-1,Poygon-1 ... etc
我想通過將名稱更改為.... Button-2,Polygon-2..etc來創建多個節點。
就像我的節點名稱是
組名稱=“ GO_P_AIn1”,我想創建“ GO_P_AIn2”,“ GO_P_AIn3”,“ GO_P_AIn3”
我想在VB.net中創建函數...每次將節點作為輸入並使用相同的節點(僅通過更改對象名稱)在輸出xml文件中創建節點數。
<group name="GO_P_AIn1" visible="true" wallpaper="false" toolTipText="/*S:0 {#102.Cfg_Tag}*/: /*S:0 #102.Cfg_Desc*/" exposeToVba="notExposed" isReferenceObject="true" linkSize="true" linkConnections="true" linkAnimations="linkWithExpression" linkBaseObject="(RA-BAS) P_AIn Graphics Library.GO_P_AIn" linkToolTipText="true">

您的問題尚不清楚。 是否要為每個生成的節點創建一個輸出xml文件? 還是要將它們全部合並到一個輸出xml文件中? 我認為您想為每個節點創建單獨的xml文件。 將這些xml文件視為文本文件,您只需將字符串“ GO_P_AIn1”替換為“ GO_P_AIn”等即可
這就是我要做的:
Dim n as Integer = 2 'The number to add
Dim objReader As New System.IO.StreamReader(XMLFilePath)
Dim output as System.IO.StreamWriter
Dim outputPath as String = XMLFilePath & n.ToString
Dim xmlContent As String = objReader.ReadToEnd
objReader.Close()
xmlContent.Replace("GO_P_AIn1", "GO_P_AIn" & n) 'Replace the content with desired number
output = My.Computer.FileSystem.OpenTextFileWriter(outputPath)
output.Write(xmlContent)
output.Close()
遍歷您要創建的節點數,這幾乎就是您需要做的
我將使用XML Linq和Regex
Imports System.Xml
Imports System.Xml.Linq
Imports System.Text.RegularExpressions
Module Module1
Sub Main()
Dim xml As String = _
"<?xml version=""1.0"" encoding=""utf-8""?>" & _
"<root>" & _
"<group name=""GO_P_AIn1"" visible=""true"" wallpaper=""false"">" & _
"<rectangle name=""AIN_AlarmPolygon1"" height=""41"" > </rectangle>" & _
"<button name=""AIN_Button_Quick1"" height=""35"" width=""140""> </button>" & _
"</group>" & _
"</root>"
Dim doc As XDocument = XDocument.Parse(xml)
Dim root As XElement = doc.Descendants("root").FirstOrDefault
Dim group As XElement = doc.Descendants("group").FirstOrDefault()
Dim groupString As String = group.ToString()
For index = 2 To 10
Dim newGroup As XElement = XElement.Parse(groupString)
root.Add(newGroup)
For Each item As XElement In newGroup.DescendantsAndSelf().Where(Function(x) Not x.Attribute("name") Is Nothing)
Dim name As XAttribute = item.Attribute("name")
Dim value As String = CType(name, String)
Dim newValue As String = Regex.Replace(value, "\d+", index.ToString())
name.Value = newValue
Next item
Next index
End Sub
End Module
