  Rule #1 to get help:
    - provide meaningful reports, what is the error ????
  Rule #2:
    - follow the instructions

      "Do not send code, I won't debug it" is in bold, maybe I need
      to make it red too.

  You cannot. You MUST escape characters which are not acceptable
XML is a text format, live with it.

  when present in content & and < are automatically escaped by libxml
when saving, so I don't understand, and without the error messages the
only possibility is to make guesses and I don't have the time for guess
play.

  Well this doesn't mean that you should not do the minimal reasearch
on your side or follow the instructions. The fact that XML requires
escaping of & and < in content is the #1 point of any beginner XML FAQ.
And you report is far too incomplete to be able to answer (and no sorry
I don't have the time to debug your code).
