XML format is supported only for displaying data, not for INSERTS. Example:

.. code-block:: xml

  <?xml version='1.0' encoding='UTF-8' ?>

If name of a column contains some unacceptable character, field is used as a name. In other aspects XML uses JSON structure.
As in case of JSON, invalid UTF-8 sequences are replaced by replacement character � so displayed text will only contain valid UTF-8 sequences.

In string values ``<`` and ``&`` are displayed as ``&lt;`` and ``&amp;``.

Arrays are displayed as ``<array><elem>Hello</elem><elem>World</elem>...</array>``,
and tuples as ``<tuple><elem>Hello</elem><elem>World</elem>...</tuple>``.
