Hi All,

I need to accomplish validate XML files with an XSD. Found libxml in packages and works as expected with Win32. But I have problem with messages on Linux 64bit. Got %s instead the real message text. I use the below code to get the messages. Any idea why not works with Linux64 bit?

var
   SL_Warning,SL_Error:TStringList;
procedure SchemaValidityWarningFunc(ctx: Pointer; const msg: PChar);
begin
   SL_Warning.Add(msg);
end;
procedure SchemaValidityErrorFunc(ctx: Pointer; const msg: PChar);
begin
   SL_Error.Add(msg);
end;

Same problem with Win64. So not Linux specific.

Are these functions callbacks ? If so, is the calling convention correct ?

I used xmlSchemaSetValidErrors and the documentation say "Set the error and warning callback informations". Tried with and without cdecl.

Meanwhile tried xmlSchemaSetValidStructuredErrors and that works with Win32, Win64 and Linux 64bit.

Is libxml package have a maintainer or is it a legacy/deprecated thing? I experienced some differences between the documentation of libxml2 and the "Interfaces for validating" section in xmlschemas.inc.

These functions use varargs, so the calling convention is different:

I thought it only works with external code, though. Would be useful if the documentation mentioned anything.

Sorry I can't read today, the documentation says external only so you are indeed out of luck it seems.
