XML Parsing in Qt 3.3

[marcel]

Could you show us your InterceptReader class? At least the error handling routines...

{
   qWarning( "Line %d, column %d: %s", exception.lineNumber( ),
                    exception.columnNumber( ), exception.message( ).ascii( ) );
   return false;

}

Like I said this is more of a test right now to make sure I can parse through the XML and grab certain items and later I will implement more of what I want to do with them. But this is my basic XML parser. Thanks for your continued help!

[vermarajeev]

what is reader.parse( &file ) value?

[ToddAtWSU]

What do you mean by

what is reader.parse( &file ) value?

It returns false if that is what you mean?

I have run my code through DBX and my stack's last 6 lines looks like

reader.parse( &file )
QXmlSimpleReader::parseBeginOrContinue
QXmlSimpleReader::parseProlog
QXmlSimpleReader::unexpectedEof
QXmlSimpleReader::reportParseError
InterceptReader::fatalError

reader.parse( &file )
QXmlSimpleReader::parseBeginOrContinue
QXmlSimpleReader::parseProlog
QXmlSimpleReader::unexpectedEof
QXmlSimpleReader::reportParseError
InterceptReader::fatalError

Thanks again!

I found my problem at least as to why I got my error. My XMLs were in a different directory than my executable and when getting a QDir, using the [] operator only returned the filename and when I created the QFile I needed to make sure to include the actual path to the files when giving the filename to create the QFile. Now that I give the path/filename the files don't error out. Thanks for your help anyways!
