Problem is, "classQChar.xml" is not a valid Uri format (it's relative, not 
absolute), and so we have to expand it to a absolute Uri format before calling 
the Uri ctor.

Fixed in CVS December 16 2004.

Summary:  XmlUrlResolver.ResolveUri() works incorrectly without a path name or 
full URI

Original Submission:  This problem is actually more general than it might 
appear at first. I first encountered problems when calling 
xmlDocument.Load("classQChar.xml"), resulting in the exception

Uncaught exception: System.ArgumentNullException: Argument cannot be null
Parameter name: absoluteUri
        at System.Xml.XmlUrlResolver.GetEntity(Uri, String, Type) in 
./XmlUrlResolver.cs:49
        at System.Xml.XmlTextReader..ctor(String, XmlNameTable) in 
./XmlTextReader.cs:302
        at System.Xml.XmlTextReader..ctor(String)
        at System.Xml.XmlDocument.Load(String) in ./XmlDocument.cs:664
        at API.AddAPIFromFile(String)
        at ApiGe.Main(String[])

XmlTextReader..ctor(String) calls resolver.ResolveUri(null, string), where 
string is the file that was to be loaded. In the case above, "classQChar.xml". 
However, ResolveUri() returns null for this string. That seems to be the real 
problem. Under MS.NET, it appears that the filename is expanded to its full 
path (if it is not of the form whatever://moreStuff).

In the test case attached, MS reports "uri is not null", whereas Pnet reports 
"uri is null".
