141 | |
180 | 142 Используется для преобразования CGI запроса в DOM документ. Для этого используются параметры запроса, имена которых |
143 начинаются со значение из свойства C<prefix>. | |
147 | 144 |
180 | 145 Имена параметров интерпретируются следующим образом |
147 | 146 |
147 =over | |
148 | |
180 | 149 =item 1 Имя параметра составляется из имени узла, имен всех его родителей и указанием номера экземпляра. |
147 | 150 |
180 | 151 =item 2 Имена узлов могут содержать только буквы, цифры и символ _ |
147 | 152 |
180 | 153 =item 3 В случае когда узел может повторяться несколько раз, в квадратных скобках указывается |
154 послеовательный номер экземпляра. | |
194 | 155 |
180 | 156 =item 4 Имена параметров объединяются через символ '/' |
