| 140 =head1 DESCRIPTION | |
| 141 | |
| 142 Используется для преобразования CGI запроса в DOM документ. Для этого используются параметры запроса, имена которых | |
| 143 начинаются со значение из свойства C<prefix>. | |
| 144 | |
| 145 Имена параметров интерпретируются следующим образом | |
| 146 | |
| 147 =over | |
| 148 | |
| 149 =item 1 Имя параметра составляется из имени узла, имен всех его родителей и указанием номера экземпляра. | |
| 150 | |
| 151 =item 2 Имена узлов могут содержать только буквы, цифры и символ _ | |
| 152 | |
| 153 =item 3 В случае когда узел может повторяться несколько раз, в квадратных скобках указывается | |
| 154 послеовательный номер экземпляра. | |
| 155 | |
| 156 =item 4 Имена параметров объединяются через символ '/' | |
| 157 | |
