Вопрос:
Я получаю ошибки при синтаксическом анализе результирующего сообщения в XML. Кто-нибудь знает почему?
Спасибо.

1. Пожалуйста, объясните / покажите ошибки, которые вы получаете
2. И покажите нам содержимое переменной
resultMessageв том месте, где вы пытаетесь ее разобрать.
Ответ №1:
Поскольку в вашем вводе все " символы были заменены на " , чтобы иметь возможность сохранить их в другой строке, это приводит к неправильным атрибутам в вашем XML.
Быстрое исправление, если ввод не может быть исправлен, состоит в разборе результирующей строки, обернутой двумя " .
