交叉引用 xml 已作为字符串加载到列表中的文件，将它们分开并从中检索特定数据

Question

Main Form Code: https://pastebin.com/31gjpzm6 < Outdated
Blueprint Input Code W/ Mods: https://pastebin.com/KsF2vAWw < Outdated

来自“%AppData%\Roaming\SpaceEngineers\Mods”的模组被提取到 "C:\SETools\unpacked_mods\" 到一个以整数命名的文件夹中，该整数等于提取的数字，因此第一个 mod 是 0，第二个是 1，依此类推。

一个典型的 mod 将有它的主数据文件 "C:\SETools\unpacked_mods[=39=]\data\CubeBlocks.sbc" 并且内部数据也在 XML 中。

CubeBlocks.sbc Mod Info File: https://pastebin.com/UhhGtEhN

所以我想做的是交叉引用蓝图文件中的 modded 子类型 ID 和所有 mod 文件中的子类型 ID，并检查它们是否匹配，如果匹配则抓取他们的 DDS 格式的图标并将其发送到已经在上面的 Form1 代码中生成的图片框。我想通过检索字符串的路径来做到这一点。

所以我的问题是我如何编写一个函数来执行此操作而不为每个 mod 编写一个 IF 函数，基本上我想制作一个 vanilla 块类型的列表并且像 if blockname 一样= 原版方块列表中的任何项目，然后运行检查 mod 的功能。

到目前为止我得到了什么：

Public Sub LoadModDefinitions()
    Dim modpath As String = "C:\SETools\unpacked_mods\"

    For Each entry In Directory.GetFiles(modpath, "CubeBlocks.sbc") 'For each zipfilename in the given directory extract them to the given folder
        Dim filereader As StreamReader = New StreamReader(modpath)
        For Each block In entry
            ModdedCubeblockDefinitions.Add(filereader.ReadToEnd(modpath))
        Next block
    Next
End Sub

^ 这会将所有 modded 块信息加载到列表中。

而有问题的功能是下面的那个我如何搜索 modded 块数据列表中的每个数据块，找出哪个包含输入 "subtypesearch" & return 该文件内容的特定块，它是“”和“/icon”之间的文件路径

Public Function SearchModdedCubeDefinitions(subtypesearch As String) 'WIP WIP WIP WIP WIP WIP
    Dim BlockToSearch As String = subtypesearch

    Return Nothing
End Function

并自动提取 mods 个文件

'Check if program has been ran before and extract all mods if it hasnt
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles Me.Load
    Try
        'Check if the program directory exists & if not then create it
        If Not Directory.Exists("C:\SETools") Then
            Try
                Directory.CreateDirectory("C:\SETools")
            Catch ex As Exception
            End Try
        End If
        'Check if the mod extraction directory exists in the C drive & if not then create it
        If Not Directory.Exists("C:\SETools\unpacked_mods") Then
            Try
                Directory.CreateDirectory("C:\SETools\unpacked_mods")
            Catch ex As Exception
            End Try
        End If
        'Check if the file that determins whether or not the program has been run before exists or not & if not then create it
        If Not File.Exists("C:\SETools\Activated.txt") Then
            Try
                File.CreateText("C:\SETools\Activated.txt")
                'Unpack all mods
                unpackAll(sepath, extractto)
            Catch ex As Exception
            End Try
        End If
    Catch ex As Exception
    End Try
End Sub

目前似乎所有文件都被毫无问题地读入字符串列表，但我什至不知道从哪里开始使用搜索功能。我已经为我之前正在做的事情编写了一个函数来搜索文本框，并且正在考虑尝试在这里实现它，但我仍然会关心如何 return 图标标签之间的文本，我是考虑使用正则表达式字符串拆分，但我不太确定任何指针？

当前搜索功能

Private Function FindWords(ByVal TextSearched As String, ByVal Paragraph As String) As Integer
    Dim location As Integer = 0
    Dim occurances As Integer = 0
    Do
        location = TextSearched.IndexOf(Paragraph, location)
        If location <> -1 Then
            occurances += 1
            location += Paragraph.Length
        End If
    Loop Until location = -1
    Return occurances
End Function

使用序列化解决问题

XMLCleaner.vb

Public Class XMLCleaner
    Public Function CleanXML(inputfile As String)
        Dim originalxml As String = inputfile
        Dim outputxml As String = Nothing

        'only keep requested xml lines and remove xsi:type from <definition> element
        For Each line In originalxml.Split(vbNewLine)
            If line.ToString().Contains("<?xml") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Definitions xmlns:xsi") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<CubeBlocks>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Definition xsi:type") Then
                outputxml += "<Definition>" + vbNewLine
            ElseIf line.ToString().Contains("<Definition>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Id>") Then
                outputxml += line.ToString() + vbNewLine

                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<TypeId>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<SubtypeId>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<DisplayName>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Icon>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<CubeSize>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<BlockPairName>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<BuildTimeSeconds>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Components>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("<Component Subtype") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("</Components>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("</Definition>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("</CubeBlocks>") Then
                outputxml += line.ToString() + vbNewLine
            ElseIf line.ToString().Contains("</Definitions>") Then
                outputxml += line.ToString() + vbNewLine
            End If
        Next

        Return outputxml
    End Function
End Class

此方法仅从每个 mod 的 cubeblocks 文件中提取需要的数据，使其可由我为回答另一个问题而制作的通用 cubeblocks 反序列化器序列化。

这 class 将 cubeblocks 文件反序列化为 DefinitionsDefinition class 的字典，见下文。

Main.vb

Public ModBlockDefinitionDictionary As New Dictionary(Of String, DefinitionsDefinition)

Public Sub LoadModDefinitions()
        Dim modpath As String = My.Settings.SpaceEngineersWorkingDirectory
        Dim id As Integer = 0
        Dim Cleaner As New XMLCleaner()

        For Each folder In Directory.GetDirectories(modpath)
            Dim folder_complete As String = folder.ToString() + "\Data"

            For Each file In Directory.GetFiles(folder_complete, "CubeBlocks.sbc") 'For each zipfilename in the given directory extract them to the given folder
                Dim moddedxml As String = Cleaner.CleanXML(System.IO.File.ReadAllText(file))
                Dim DefinitionData As New Definitions()
                Dim xmlSerializer As XmlSerializer = New XmlSerializer(GetType(Definitions))

                Try
                    Dim streamread As New StringReader(moddedxml)
                    DefinitionData = xmlSerializer.Deserialize(streamread)
                Catch ex As Exception

                End Try

                For Each BlockDefinition In DefinitionData.CubeBlocks()
                    Try
                        If Not ModBlockDefinitionDictionary(BlockDefinition.Id.SubtypeId.ToString()) Is Nothing Then
                            'Block already exists dont add it
                        Else
                            ModBlockDefinitionDictionary.Add(BlockDefinition.Id.SubtypeId.ToString(), BlockDefinition)
                        End If
                    Catch ex As Exception

                    End Try
                Next
            Next

            id += 1
        Next
    End Sub

然后对于每个要检查的 mod 方块，您可以使用其子类型 ID 作为键从 ModBlockDefintionsDictonary 中获取该方块。
