Simple Python to XML library.

Project Description
[![Build Status](https://secure.travis-ci.org/skimhub/pyToXml.png?branch=master)](http://travis-ci.org/skimhub/pyToXml)

# Synopsis

from pytoxml import PyToXml

person_details = {
"name": "Bob",
"occupation": "Builder",
"arrests": [
"Assault / Battery",
"Indecent Exposure"
]
}

p2x = PyToXml("doc", person_details)
print p2x.encode()

Yields:

<doc>
<arrests>
<item>Assault / Battery</item>
<item>Indecent Exposure</item>
</arrests>
<name>Bob</name>
<occupation>Builder</occupation>
</doc>

# Introduction

pytoxml gives you a simple way of converting a python structure to
XML.

# Tests

Run the test suite with `py.test` (`pip install pytest`) from the root
of the project.

# Pluralisation of lists

By default pytoxml will use the element name `item` which is probably
not what you want. Here's a simple example of how you might use a map
to determine the best phrase for a list element:

class BetterListsDemo(PyToXml):
def pluralisation(self, plural):
pluralisation_map = {
"arrests": "arrest"
}

return pluralisation_map.get(plural) or "item"

p2x = BetterListsDemo("doc", person_details)
print p2x.encode()

Which gives:

<doc>
<arrests>
<arrest>Assault / Battery</arrest>
<arrest>Indecent Exposure</arrest>
</arrests>
<name>Bob</name>
<occupation>Builder</occupation>
</doc>

The `pluralisation` function takes `plural` as an argument which is
the name of the direct parent element to the one you'll be creating.

# Custom Handlers

By default pytoxml will only encode a few types, if you want to
encode, for example, exceptions, you might do the following:

def temp_convertor(structure, element, name):
element.text = str(structure)

p2x = PyToXml("a", { "b": Exception("Should now serialise") })
p2x.add_type_handler(Exception, temp_convertor)
self.assertEqual(str(p2x.encode()), "<a><b>Should now serialise</b></a>")

If you give an object a `__pytoxml__` method then you don't need to
register a handler:

class MyException(Exception):
def __pytoxml__(self, structure, element, name):
element.text = str(self)

p2x = PyToXml("a", { "b": MyException("Should now serialise") })
self.assertEqual(str(p2x.encode()), "<a><b>Should now serialise</b></a>")

# CData and attributes

Though it's somewhat orthogonal to the original justification of
PyToXml, you can easily output CDATA elements and attributes:

from pytoxml import PyToXml

cdata = pytoxml.CData("<crappy>xml")
attributes = pytoxml.Attributes("simple text", {"one": "two"})

p2x = pytoxml.PyToXml("root", { "raw": cdata, "attributed": attributes })
p2x.encode()

gives (un-formatted):

<?xml version="1.0"?>
<root>
<raw><![CDATA[<crappy>xml]]></raw>
<attributed one="two">simple text</attributed>
</root>

# Constructor Options

## xml_declaration

Output the XML declaration. Defaults to `False`.

p2x = PyToXml("doc", "hello", encoding="latin1", xml_declaration=True)
print p2x.encode()

Yields:

<?xml version='1.0' encoding='latin1'?>
<doc>hello</doc>

## encoding

# Attributes on the root element

p2x = PyToXml("a", { }, root_attributes={"one": "two"} )
p2x.encode()

gives:

<a one="two"/>

Which encoding system should be used to build Defaults to `UTF-8`.
