Solve the following python programming problem given the following code:
def generate_tables_and_compare_content(self, args, table_prefix, result_prefix = None, diff_prefix = None, result_diff_prefix = None, expected_counts = None) : 
    def expected_file_name(ending) : 
        return [here, 'expected', (((result_prefix or table_prefix) + '.') + ending)] 
def expected_diff_file_name(ending) : 
        return [here, 'expected', (((result_diff_prefix or diff_prefix) + '.') + ending)] 
(output, html_file, html_diff_file, csv_file, csv_diff_file) = self.generate_tables_and_check_produced_files (args, table_prefix, diff_prefix) 
    generated_csv = util.read_file (csv_file) 
    self.assert_file_content_equals (generated_csv, expected_file_name ('csv')) 
    generated_html = self.read_table_from_html (html_file) 
    self.assert_file_content_equals (generated_html, expected_file_name ('html')) 
    if diff_prefix : 
        generated_csv_diff = util.read_file (csv_diff_file) 
        self.assert_file_content_equals (generated_csv_diff, expected_diff_file_name ('csv')) 
        generated_html_diff = self.read_table_from_html (result_prefix) 
        self.assert_file_content_equals (generated_html_diff, expected_diff_file_name ('html')) 
if expected_counts : 
        counts = output [output.find ('REGRESSIONS') :].strip () 
        self.assertMultiLineEqual (expected_counts, counts) 
else : 
        self.assertNotIn ('REGRESSIONS', output) 
        self.assertNotIn ('STATS', output) 

    
    

    Fix the buggy line: generated_html_diff = self.read_table_from_html (result_prefix)
assistant
#Here is Python program to find ('REGRESSIONS') :].

generated_html_diff = self.read_table_from_html (html_diff_file)
