Project description
Simple XML Python Marsheller
pysxm is a simple and extensible xml python marsheller. It comes with the following pre-defined types:
DateTimeType
DateType
TimeType
SimpleType
ComplexType
Installation
pip install pysxmThings to know
For all types, the default tagname is the lowercased name of the class e.g for class Color(SimpleType) we will have <color>. You can set the attribute _tagame to customize the xml elemnt tagname. For ComplexType you can decide of the order of attribute to serialize and which one should be serialized by setting the _sequence attribute.
pysxm uses lxml objectify under the hood. To manipulate the xml object of your class:
In [16]: class Person(ComplexType):
...: _tagname = 'personne'
...: _sequence = ('lname', 'fname')
...: def __init__(self, fname, lname):
...: self.fname = fname
...: self.lname = lname
...:
In [17]: token = Person('token', 'black')
In [18]: token.xml
Out[18]: <Element personne at 0x7f85c0df2e60>
In [26]: print(token)
<personne xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<lname>black</lname>
<fname>token</fname>
</personne>Note that the tag name is not the expected one, because of:
_tagname = 'personne'Example
In [1]: from pysxm import SimpleType, ComplexType, DateType
In [2]: class BirthDate(DateType):
...: pass
...:
In [3]: class Profile(SimpleType):
...: allowed_values = ('teacher', 'student')
...:
In [4]: class User(ComplexType):
...:
...: sequence = ('username', 'profile', 'birtdate')
...:
In [5]: class User(ComplexType):
...:
...: sequence = ('username', 'profile', 'birtdate')
...:
In [6]: class User(ComplexType):
...:
...: sequence = ('username', 'profile', 'birthdate')
...: def __init__(self, data):
...: self.username = data['username']
...: self.profile = Profile(data['profile'])
...: self.birthdate = BirthDate(data['birthdate'])
...:
In [8]: data = {
...: 'username': 't0k3n',
...: 'profile': 'student',
...: 'birthdate': '2007-06-20'}
In [11]: token = User(data)
In [12]: print(token)
<user xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<username>t0k3n</username>
<profile>student</profile>
<birthdate>2007-06-20</birthdate>
</user>
# SAVING ELEMENT INTO FILE
In [1]: p = Person('token', 'black')
In [2]: p.save('person.xml')
In [3]: cat person.xml
<person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<lname>black</lname>
<fname>token</fname>
</person>
