SetXMLAttribute() work fine, so what i am doing wrong with GetXMLAttribute() ? it dont work.

file : plan.xml

<mesh>
    <submeshes>
        <submesh material="plan/system" usesharedvertices="false" use32bitindexes="false" operationtype="triangle_list">
            <faces count="2">
                <face v1="2" v2="1" v3="0" />
                <face v1="0" v2="3" v3="2" />
            </faces>
            <geometry vertexcount="4">
                <vertexbuffer positions="true" normals="true" texture_coord_dimensions_0="2" texture_coords="1">
                    <vertex>
                        <position x="0" y="0" z="0" />
                        <normal x="0" y="1" z="0" />
                        <texcoord u="-2" v="-2" />
                    </vertex>
                    <vertex>
                        <position x="1" y="0" z="0" />
                        <normal x="0" y="1" z="0" />
                        <texcoord u="2" v="-2" />
                    </vertex>
                    <vertex>
                        <position x="1" y="0" z="1" />
                        <normal x="0" y="1" z="0" />
                        <texcoord u="2" v="2" />
                    </vertex>
                    <vertex>
                        <position x="0" y="0" z="1" />
                        <normal x="0" y="1" z="0" />
                        <texcoord u="-2" v="2" />
                    </vertex>
                </vertexbuffer>
            </geometry>
        </submesh>
    </submeshes>
</mesh>

Code: Select all

file$ = "plan.xml"

Procedure AddNode(*Node, Position)
  name$ = GetXMLNodeName(*Node)
  AddGadgetItem (0, -1, name$, 0, position) 
  If name$ = "face"
    SetXMLAttribute(*Node,"v1","1234")
    ;ExamineXMLAttributes(*Node)
    ;While NextXMLAttribute(*Node)
      Debug GetXMLAttribute(*Node, "v1")
      Debug GetXMLAttribute(*Node, "v2")
      Debug GetXMLAttribute(*Node, "v3")
    ;Wend  
    Debug "----"
  EndIf  
  For child = 1 To XMLChildCount(*Node)
    *child = ChildXMLNode(*Node, child)
    AddNode(*child, position+1)
  Next  
EndProcedure

OpenWindow(0, 0, 0, 355, 280, "TreeGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
CreateGadgetList(WindowID(0))
TreeGadget(0, 10, 10, 260, 260)                                         
tree = LoadXML(#PB_Any, file$)
status = XMLStatus(tree)
If status=0
  AddNode(MainXMLNode(tree), 0)
EndIf
SaveXML(tree,"test.xml")

Repeat

Until WaitWindowEvent() = #PB_Event_CloseWindow

Well, as far as I can see what you have there should work. ExamineXMLAttributes() is succeeding, so the node type is correct, SetXMLAttribute() is returning non-zero, and while no return value is documented for this command, it would seem to indicate success. My skill with this new library is as limited as your own, but imho you haven't made any errors.

After extensive testing, I am convinced there is a bug in GetXMLAttribute()

In the meantime, as a workaround, write a procedure:

Code: Select all

Procedure.s GetXMLAttrib(*Node, name$)
If XMLNodeType(*Node)=#PB_XML_Normal
  ExamineXMLAttributes(*node)
  While NextXMLAttribute(*node)
    If XMLAttributeName(*node)=name$
      ProcedureReturn XMLAttributeValue(*node)
    EndIf
  Wend
EndIf
EndProcedure

Then call it like this:

Code: Select all

    Debug GetXMLAttrib(*Node, "v1")
    Debug GetXMLAttrib(*Node, "v2")
    Debug GetXMLAttrib(*Node, "v3")
