# XmlModels2

XmlModels allows you to define Models similar in nature to Django models that are backed by XML endpoints rather than a
database. Using a familiar declarative definition, the fields map to values in the XML document by means of XPath
expressions. With support for querying external REST APIs using a django-esque approach, we have strived to make
writing and using xml backed models as close to django database models as we can, within the limitations of the
available API calls.

# Installation

The simplest approach is to to use `pip install xml_models2`

# A simple example

Just to get started, this is an example of taking an XML representation of an Address that might be returned from a
GET request to an external REST api.

<Address id="2">
<number>22</number>
<street>Acacia Avenue</street>
<city>Maiden</city>
<country>England</country>
<postcode>IM6 66B</postcode>
</Address>

class Address(xml_models.Model):
id=xml_models.IntField(xpath="/Address/@id")
number = xml_models.IntField(xpath="/Address/number")
street = xml_models.CharField(xpath="/Address/street")
city = xml_models.CharField(xpath="/Address/city")
country = xml_models.CharField(xpath="/Address/country")
postcode = xml_models.CharField(xpath="/Address/postcode")

finders = {(id,): 'http://adresses/%s'}

This example would be used as follows:-

>>> address = Address.objects.get(id=2)
>>> print "address is %s, %s" % (address.number, address.street)
"22, Acacia Avenue"
