EasyXSD

Easy XML Schema Definition (XSD) validation of XML documents based on lxml.

Usage:

>>> from easyxsd import *
>>> xsd = xsd_from_file('/path/to/files/definitions.xsd')
>>> xml = xml_from_file('/path/to/files/valid-example.xml')
>>> xsd.validate(xml)
True
>>> xml = xml_from_file('/path/to/files/invalid-example.xml')
>>> xsd.validate(xml)
False

The xml and xsd objects are lxml's lxml.etree._ElementTree and lxml.etree.XMLSchema objects respectively.

More information on the available API:

validate(xml, xsd)
    Receives an lxml.etree._ElementTree object as first parameter
    and an lxml.etree.XMLSchema object as second parameter and
    returns True or False respectively as the XSD validation of the
    XML succeeds or fails.

validate_from_files(xmlfilepath, xsdfilepath)
    Receives a string with a file path to a valid XML document 
    as first parameter and another string with a file path to a valid
    XSD document as second parameter and validates the first according 
    to the latter returning True or False respectively as the validation
    succeeds or fails.

validate_from_strings(xmlstr, xsdstr)
    Receives a string containing a valid XML document as first parameter
    and another string containing a valid XSD document as second parameter
    and validates the first according to the latter returning True or False
    respectively as the validation succeeds or fails.

validate_with_errors(xml, xsd)
    Returns a tuple with a boolean product of the XSD validation as
    the first element and the error log object as the second element.

validate_xml_string_from_xsd_file(xmlstr, xsdfilepath)
    Validates a string containing an XML document as the first parameter
    with an XSD document contained in the file path passed as the
    second parameter.

xml_from_file(filepath)
    Returns an lxml.etree._ElementTree object from a file
    containing a valid XML document.

xml_from_string(xmlstr)
    Returns an lxml.etree._ElementTree object from a string
    containing a valid XML document.

xsd_error_as_simple_string(error)
    Returns a string based on an XSD error object with the format
    LINE:COLUMN:LEVEL_NAME:DOMAIN_NAME:TYPE_NAME:MESSAGE.

xsd_error_log_as_simple_strings(error_log)
    Returns a list of strings representing all the errors of an XSD
    error log object.
