Delphi XE2/2007 and LibXML

IDEs on separate machines both WinXP. The versions/date of LibXML2.dll vary in both machines from 2010 to 2012.

I am installing libxml2.pas from SourceForge (2.7.3) I created 3 apps, a console and a VCL Forms on XE2 and a VCL Forms on D2007.

If I do not reference a function in the Libxml2.dll my app runs, if I reference a function e.g. Doc:=xxmlParseFile(xnldocptr) the app crashes at start up in InitUnits.

program Project25;

uses
  Forms,

      Unit26 in 'Unit26.pas' {Form26};

    {$R *.res}


begin<---------- Access violation here
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TForm26, Form26);
  Application.Run;
end.

AV Message

//Main Firm uses Libxml2; 

{$R *.dfm} 

procedure TForm26.FormCreate(Sender: TObject); var Doc: xmlDocPtr; 
begin 
 Doc:=xmlParseFile('c:\a.xml'); 
 xmlFreeDoc(Doc); 
end

I can see that the module LibXML2 has been loaded.

Am I doing something silly or missing something?

LIBXML2.DLL itself depends on 2 other DLL's: ICONV.DLL and ZLIB1.DLL

You can download the latest version of these dll's here

Make sure that these DLL's reside on the same path as your delphi executable.

I have tested your project under W7/Delphi XE and I don't receive an AV.
