#Note that the argument can be also a file-like object or a string containing the schema definition. See examples 1 and 2 bellow :


# Exemple 1: 
#schema_file = open('tests/test_cases/examples/collection/collection.xsd')
#schema = xmlschema.XMLSchema(schema_file)

#Example 2 : 
#schema = xmlschema.XMLS chema("""
#<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
#<xs:element name="block" type="xs:string"/>
#</xs:schema>
#""")

   # print('Validated with success !')
#else :

#Peut aussi être utilisée comme suit : 
#fichier_xsd = 'commande1.xsd'
#fichier_xml = 'commande.xml'
#xmlschema.validate (fichier_xml, schema=fichier_xsd)
