class libtaxii.validation.SchemaValidator(schema_file)

A helper class for TAXII Schema Validation.

Example

See validate_etree(…) for an example how to use this class

validate_etree(etree_xml)

Validate an LXML etree with the specified schema_file.

Parameters:

• etree_xml (etree) – The XML to validate.
• schema_file (str) – The schema file to validate against

Returns:

A SchemaValidationResult object

Raises:

lxml.etree.XMLSyntaxError – When the XML to be validated is not well formed

Example

from libtaxii import messages_11
from libtaxii.validation import SchemaValidator, TAXII_11_SCHEMA
from lxml.etree import XMLSyntaxError

sv = SchemaValidator(TAXII_11_SCHEMA)

try:
   result = sv.validate_etree(some_etree)
   # Note that validate_string() and validate_file() can also be used
except XMLSyntaxError:
    # Handle this exception, which occurs when
    # some_xml_string is not valid XML (e.g., 'foo')

if not result.valid:
    for error in result.error_log:
        print error
    sys.exit(1)

# At this point, the XML is schema valid
do_something(some_xml_string)

validate_file(file_location)

A wrapper for validate_etree. Parses file_location, turns it into an etree, then calls validate_etree( … )

validate_string(xml_string)

A wrapper for validate_etree. Parses xml_string, turns it into an etree, then calls validate_etree( … )
