ExtractXMLMap

[bohne_68]

Hallo,

i try to write and to read a MAP using the xml-features.

Code: Select all

  Procedure SaveSettings()
    Define FileName.s
    
    If MapSize(SettingsData()) > 0              
      If CreateXML(0) And InsertXMLMap(CreateXMLNode(RootXMLNode(0), "settings"), SettingsData())
        FileName = SettingsFileName() 
        SaveXML(0, FileName)
        FreeXML(0)          
      Else
        Debug XMLError(0)
      EndIf
    EndIf
  EndProcedure

  Procedure LoadSettings()
    Define FileName.s
    
    FileName = SettingsFileName()
    If FileSize(FileName) >= 0       
      If LoadXML(0, FileName) And XMLStatus(0) = #PB_XML_Success
        ExtractXMLMap(MainXMLNode(0), SettingsData())
        FreeXML(0)
      Else
        Debug XMLError(0)
      EndIf           
    EndIf
  EndProcedure

It is not possible to get the map back. Can somebody tell me, what is going wrong?

Thanks
Thomas

ExtractXMLMap is for when working with a string as far as I can tell :

Code: Select all

Xml$ = "<map><element key=" + Chr(34) + "theKey" + Chr(34) + ">the value</element></map>"
  
  If ParseXML(0, Xml$) And XMLStatus(0) = #PB_XML_Success
    NewMap Test.s()
    ExtractXMLMap(MainXMLNode(0), Test())
    
    ForEach Test()
      Debug MapKey(Test()) + " -> " + Test()
    Next
  Else
    Debug XMLError(0)
  EndIf

When I was working with XML I had to use much more convoluted methods to load my XML from disk then parse the file myself. I'm not sure if things have gotten easier since then

Code: Select all

Procedure ImportDataFile_XML(*CurrentNode, CurrentSublevel.i)
  
  Protected NodeName.s, *ChildNode, AttributeName.s, FilenameString.s, PictureFileName.s, *Buffer
  Protected FileSize.i, PictureFileHandle.i, FileNamesCountLoop.i, FileNamePart.s
  Protected FileExtensionPart.s, Separator.s
  
  If XMLNodeType(*CurrentNode) = #PB_XML_Normal
    NodeName.s = GetXMLNodeName(*CurrentNode)
    
    ;;do stuff With the node data
    
    *ChildNode = ChildXMLNode(*CurrentNode)
    
    While *ChildNode <> 0
      
      ImportDataFile_XML(*ChildNode, CurrentSublevel + 1)
      *ChildNode = NextXMLNode(*ChildNode)
    Wend
    
  EndIf
  
EndProcedure

Procedure ImportDataFile()
  Protected.i XML
  Protected.q ImdbXMLFileSize.q
  Protected *Buffer, *Node
  ImdbXMLFile.i = ReadFile(#PB_Any, "level.xml")
  If ImdbXMLFile.i
    ImdbXMLFileSize.q = Lof(ImdbXMLFile.i)
    If ImdbXMLFileSize.q
      *Buffer = AllocateMemory(ImdbXMLFileSize.q)
      If *Buffer
        If ReadData(ImdbXMLFile, *Buffer, ImdbXMLFileSize.q) = ImdbXMLFileSize.q
          XML = CatchXML(#PB_Any, *Buffer, ImdbXMLFileSize.q)
          If XML
            *Node = MainXMLNode(XML)
            If *Node
              ImportDataFile_XML(*Node, 0)
            EndIf
            FreeXML(XML)

          EndIf
        EndIf
        FreeMemory(*Buffer)
      EndIf
      CloseFile(ImdbXMLFile.i)
    EndIf
  EndIf
EndProcedure

Thanks for your replay. I'am also tried the convertion to a string using the Method ComposeXML() with the same result.
Now I'am using the classical implementation, pasing the XML-tree manualy.
