Rafael,
That is exactly what it is supposed to do.
XML has very strict rules about the characters that can be used for
element names and element values.
Some characters albeit not permitted inside element values can be
translated into character encoded sequences (<, >, &).
Other are not even allowed: accented chars for example.
XML does provide a mean to send element values that contain invalid
characters unencoded. That is done via a CDATA element value.
In 4D you do that by adding a '*' as a 3rd parameter to DOM SET
ELEMENT VALUE, as in:
> DOM SET XML ELEMENT VALUE($elem;$answer;*)
Javascript xml tools handle CDATA sections properly and you should not
have to do anything special on AJAX side.
Adding the '*' as above should do the trick.
