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

		initialize( relationString.trim( ) );

	 * Initialize tableInfos by analyzing the input string.
	 * @param relationString

	private void initialize( String relationString ) throws OdaException
	{
		if( relationString == null|| relationString.length() == 0)
			throw new OdaException( " The input string cannot be null/blank. ");
		
		String[] tables = relationString.split( CONST_TABLE_DELIMITER );
		for ( int i = 0; i < tables.length; i++ )
		{
			String[] temp = tables[i].trim( )
					.split( CONST_TABLE_COLUMN_DELIMITER );
			assert ( temp.length == 3 );
			
			TableInfo tableInfo = new TableInfo( temp[0].trim( ),
					temp[1].substring( 1, temp[1].length( ) - 1 ).trim( ) );
			
			String[] columns = temp[2].trim( ).split( CONST_COLUMN_DELIMITER );
