PyConvert
Converts python objects in xml or json documents, and viceversa.
Installation
You must have installed python 2.7 or 3.3+.
Download the api from github (https://github.com/rancavil/python-convert/archive/master.zip).
Unzip python-convert-master.zip
$ unzip python-convert-master.zip
Go to the directory and install the api.
$ cd python-convert-master
$ python setup.py install
Or you can install it using.
$ pip install pyconvert
Example
With pyconvert you can transform and serialize a python object in a xml or json document.
Examples:
Convert a python object in a python dictionary (json).
Create the file example_json.py
#!/usr/bin/env python
import pyconvert.pyconv
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
p = Person("Rodrigo",30)
json_person = pyconvert.pyconv.convert2JSON(p)
print(json_person)
print("name : %s"%json_person['name'])
print("age : %d"%json_person['age'])
This example convert a python object Person in a python dict (json document).
$ python example_json.py
The output must be:
{u'age':30, u'name':u'Rodrigo'}
name : Rodrigo
age : 30
Convert a python object in a python xml.dom.minidom.Document (xml).
Create the file example_xml.py
#!/usr/bin/env python
import pyconvert.pyconv
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
p = Person("Rodrigo",30)
xml_person = pyconvert.pyconv.convert2XML(p)
print(xml_person.toprettyxml())
This example convert a python object Person in a python xml.dom.minidom.Document.
$ python example_xml.py
The output must be:
<?xml version="1.0" ?>
<Person>
<age>30</age>
<name>Rodrigo</name>
</Person>
A little more complex example.
Create a file called example_order.py
#!/usr/bin/env python
import pyconvert.pyconv
class Book(object):
isbn = int
name = str
class Order(object):
number = int
book = [Book]
b1 = Book()
b1.isbn = 135573023167
b1.name = "Learning Python"
b2 = Book()
b2.isbn = 978602122321
b2.name = "Temporada de Zopilotes"
order = Order()
order.number = 331
order.book = [b1,b2]
print("\n")
json_doc = pyconvert.pyconv.convert2JSON(order)
print(json_doc)
print("\n")
xml_doc = pyconvert.pyconv.convert2XML(order)
print(xml_doc.toprettyxml())
Save and execute the example:
$ python example_order.py
The output must be:
{u'books': [
{u'isbn': 135573023167, u'name': u'Learning Python'},
{u'isbn': 978602122321, u'name': u'Temporada de Zopilotes'}
],
u'number': 331}
<?xml version="1.0" ?>
<Order>
<books>
<Book>
<isbn>135573023167</isbn>
<name>Learning Python</name>
</Book>
<Book>
<isbn>978602122321</isbn>
<name>Temporada de Zopilotes</name>
</Book>
</books>
<number>331</number>
</Order>
Create a file called example_music.py
#!/usr/bin/env python
import pyconvert.pyconv
class Band(object):
name_band = str
year_band = int
class Album(object):
band_album = Band
name_album = str
year_album = int
song = [str]
band = Band()
band.name_band = "Led Zeppelin"
band.year_band = 1968
album = Album()
album.band_album = band
album.name_album = "House of Holy"
album.year_album = 1973
album.song = list()
album.song.append("The Song Remains the Same")
album.song.append("The Rain Song")
album.song.append("Over the Hills and Far Away")
album.song.append("The Crunge")
album.song.append("Dancing Days")
album.song.append("D'yer Mak'er")
album.song.append("No Quarter")
album.song.append("The Ocean")
print("")
json_doc = pyconvert.pyconv.convert2JSON(album)
print(json_doc)
print("")
xml_doc = pyconvert.pyconv.convert2XML(album)
print(xml_doc.toprettyxml())
Save and execute the program:
$ python example_music.py
You must see the next output.
{u'year_album': 1973,
u'name_album': u'House of Holy',
u'songs': [
u'The Song Remains the Same',
u'The Rain Song',
u'Over the Hills and Far Away',
