Overview

pyxser stands for python xml serialization and is a python object to XML serializer that validates every XML deserialization against the pyxser 1.0 XML Schema. pyxser is written entirely in C as a python extension. The current stable release is pyxser-1.4.2r and supported Python version comes from 2.5 to 2.7. It uses an O(n) algorithm for serialization and other one of O(n) for deserialization, and both algorithms are recursive, but none of both are using arguments that could affect the stack, with a default max depth of 50 iterations.

Features

• Standards based serialization.
• Standards based XML validation.
• C14N based serialization, as optional kind of output.
• Model based XML serialization, represented on XML Schema and XML DTD.

Using pyxser

Using pyxser is a quiet simple:

### first import the extension from python source
import pyxser

# serialize an object
serialized = pyxser.serialize(obj = test, enc = "utf-8", depth = 0)
print "Serialized Object:\n" + serialized

# validate the object serialization
print "Serialized Object Validation:\n", pyxser.validate(serialized, enc = "utf-8")

# unserialize the object
unserialized = pyxser.unserialize(obj = serialized, enc = "utf-8")

# serialize using the C14N standard
serialized = pyxser.serialize_c14n(obj = test, depth = 0, exc = 0, com = 0)
print "Serialized Object:\n" + serialized

# validate the C14N serialization
print "Serialized Object Validation:\n", pyxser.validate_c14n(obj = serialized, enc = "utf-8")

# deserialize the C14N object
unserialized = pyxser.unserialize(obj = serialized, enc = "utf-8")

# use the C14N strict mode
serialized = pyxser.serialize_c14n_strict(obj = test, depth = 0, exc = 0, com = 0)

# cleanup the libxml2 parser 
pyxser.xmlcleanup()
