Bug 120036 Preview of XML attributes is not working
The XML attribute values are not working in the current BIRT XML ODA driver. Only 'text'-type XML elements' values are displayable in Preview. ColumnMapping XPath expressions like "@attributeName" are broken in Preview. I'll attach document showing the problem and sample XML/XSD data

	private String path;
	private String originalPath;

	public ColumnInfo( int index, String name, String type, String path, String originalPath ) throws OdaException
	{
		this.index = index;
		this.name = name;
		this.type = type;
		if( !DataTypes.isValidType( type ) )
			throw new OdaException( "The given data type name is invalid.");
		this.path = buildPath( path );
		this.originalPath = originalPath;
	}
