Somehow, sometimes the code below generates an error when loading valid Windows-1252 XML.
It fails on Windows XP Professional x86 SP3 using MSXML6.
It succeeds on Windows 7 Ultimate x64 SP1 using MSXML6.
Note: the code below is written in Delphi, but equivalent code also fails in other environments.
procedure TXMLEOSErrorTestCase.Test;
var
XmlDocument: IXMLDOMDocument3;
XmlFileName: string;
begin
XmlDocument := CoFreeThreadedDOMDocument60.Create();
XmlFileName := TPath.Combine(TPath.GetDirectoryName(ParamStr(0)), '1-Normal.xml');
if not XmlDocument.load(XmlFileName) then
Parse(XmlDocument.parseError);
end;
This error occurs during the XmlDocument.load method:
reason: System error: -2146697210.
errorCode: -2146697210
url: C:emp1-Normal.xml
I trimmed the XML down to the XML found below.
This is the hex dump of the XML file:
000000: 3C 3F 78 6D 6C 20 76 65 72 73 69 6F 6E 20 3D 20 <?xml version =
000010: 22 31 2E 30 22 20 65 6E 63 6F 64 69 6E 67 3D 22 "1.0" encoding="
000020: 57 69 6E 64 6F 77 73 2D 31 32 35 32 22 3F 3E 3C Windows-1252"?><
000030: 52 4F 57 20 43 69 74 79 3D 22 E0 22 2F 3E 0D 0A ROW City="."/>..
This is the XML:
<?xml version = "1.0" encoding="Windows-1252"?><ROW City="à"/>
Why does the error occur?
(The XML loads perfectly fine in .NET and other environments not using MSXML6, it also works fine on Windows 7 Ultimate x64 SP1).
