always Parse error "Error document empty"

[Ikmaus]

I use an self-compiled TinyXML-lib within my borland 5.0-project. The static-lib UI use was also built with the borland 5.0 compiler. I get always an Parse error "Error document empty." for every XML-file.

code-sample:

TiXmlDocument doc("metadata.xml");
bool loadOkay = doc.LoadFile("metadata.xml");

// loadOkay alwasy false because
//
// bool TiXmlDocument::LoadFile( FILE* file, TiXmlEncoding encoding )
// {
//    .... Parse( ...)

// returns alwasy false.

metadata.xml:

<?xml version="1.0"?>
