This is a reimplemetation of :func:`codecs.getwriter` that returns a :class:`~codecs.StreamWriter` that resists issuing tracebacks. The :class:`~codecs.StreamWriter` that is returned uses :func:`kitchen.text.converters.to_bytes` to convert :class:`unicode` strings into byte :class:`str`. The departures from :func:`codecs.getwriter` are: 1) The :class:`~codecs.StreamWriter` that is returned will take byte :class:`str` as well as :class:`unicode` strings. Any byte :class:`str` will be passed through unmodified. 2) The default error handler for unknown bytes is to ``replace`` the bytes with the unknown character (``?`` in most ascii-based encodings, ``�`` in the utf encodings) whereas :func:`codecs.getwriter` defaults to ``strict``.

XML also denies the use of certain bytes in the encoded text (example: ``ASCII Null``). There are also special characters that must be escaped if they are present in the input (example: ``<``). This function takes care of all of those issues for you. There are a few different ways to use this function depending on your needs. The simplest invocation is like this:: unicode_to_xml(u'String with non-ASCII characters: <"á と">') This will return the following to you, encoded in :term:`utf-8`:: 'String with non-ASCII characters: <"á と">' Pretty straightforward. Now, what if you need to encode your document in something other than :term:`utf-8`? For instance, ``latin-1``? Let's see:: unicode_to_xml(u'String with non-ASCII characters: <"á と">', encoding='latin-1') 'String with non-ASCII characters: <"á と">' Because the ``と`` character is not available in the ``latin-1`` charset, it is replaced with ``と`` in our output. This is an xml character reference which represents the character at unicode codepoint ``12392``, the ``と`` character. When you want to reverse this, use :func:`xml_to_unicode` which will turn a byte :class:`str` into a :class:`unicode` string and replace the xml character references with the unicode characters. XML also has the quirk of not allowing :term:`control characters` in its output. The :attr:`control_chars` parameter allows us to specify what to do with those. For use cases that don't need absolute character by character fidelity (example: holding strings that will just be used for display in a GUI app later), the default value of ``replace`` works well:: unicode_to_xml(u'String with disallowed control chars: \u0000\u0007') 'String with disallowed control chars: ??' If you do need to be able to reproduce all of the characters at a later date (examples: if the string is a key value in a database or a path on a filesystem) you have many choices. Here are a few that rely on ``utf-7``, a verbose encoding that encodes :term:`control characters` (as well as non-:term:`ASCII` unicode values) to characters from within the :term:`ASCII` printable characters. The good thing about doing this is that the code is pretty simple. You just need to use ``utf-7`` both when encoding the field for xml and when decoding it for use in your python program:: unicode_to_xml(u'String with unicode: と and control char: \u0007', encoding='utf7') 'String with unicode: +MGg and control char: +AAc-' # [...] xml_to_unicode('String with unicode: +MGg and control char: +AAc-', encoding='utf7') u'String with unicode: と and control char: \u0007' As you can see, the ``utf-7`` encoding will transform even characters that would be representable in :term:`utf-8`. This can be a drawback if you want unicode characters in the file to be readable without being decoded first. You can work around this with increased complexity in your application code:: encoding = 'utf-8' u_string = u'String with unicode: と and control char: \u0007' try: # First attempt to encode to utf8 data = unicode_to_xml(u_string, encoding=encoding, errors='strict') except XmlEncodeError: # Fallback to utf-7 encoding = 'utf-7' data = unicode_to_xml(u_string, encoding=encoding, errors='strict') write_tag('%s' % (encoding, data)) # [...] encoding = tag.attributes.encoding u_string = xml_to_unicode(u_string, encoding=encoding) Using code similar to that, you can have some fields encoded using your default encoding and fallback to ``utf-7`` if there are :term:`control characters` present. .. note:: If your goal is to preserve the :term:`control characters` you cannot save the entire file as ``utf-7`` and set the xml encoding parameter to ``utf-7`` if your goal is to preserve the :term:`control characters`. Because XML doesn't allow :term:`control characters`, you have to encode those separate from any encoding work that the XML parser itself knows about. .. seealso:: :func:`bytes_to_xml` if you're dealing with bytes that are non-text or of an unknown encoding that you must preserve on a byte for byte level. :func:`guess_encoding_to_xml` if you're dealing with strings in unknown encodings that you don't need to save with char-for-char fidelity.

Use this when you have a byte :class:`str` representing text that you need to make suitable for output to xml. There are several cases where this is the case. For instance, if you need to transform some strings encoded in ``latin-1`` to :term:`utf-8` for output:: utf8_string = byte_string_to_xml(latin1_string, input_encoding='latin-1') If you already have strings in the proper encoding you may still want to use this function to remove :term:`control characters`:: cleaned_string = byte_string_to_xml(string, input_encoding='utf-8', output_encoding='utf-8') .. seealso:: :func:`unicode_to_xml` for other ideas on using this function smbyte_string_to_xml can only take a byte string as its first argument.

It takes a byte :class:`str` (presumably read in from an xml file) and expands all the html entities into unicode characters and decodes the byte :class:`str` into a :class:`unicode` string. One thing it cannot do is restore any :term:`control characters` that were removed prior to inserting into the file. If you need to keep such characters you need to use :func:`xml_to_bytes` and :func:`bytes_to_xml` or use one of the strategies documented in :func:`unicode_to_xml` instead.
