Validation
----------
The **STIX Document Validator (sdv)** can perform the following forms of
STIX document validation:
* `STIX XML Schema`_: Validate STIX documents against bundled or external
STIX schemas.
* `STIX Profiles`_: Verify STIX Profile conformance (**experimental**)
* `STIX Best Practices`_: Verify alignment with STIX Best Practices.
The following forms of CybOX document validation are also possible:
* `CybOX XML Schema`_
Dependencies
------------
The **STIX Document Validator** has the following dependencies:
* `Python`_: Python interpreter
* `lxml`_ >= v3.2.0: XML processing library.
* `libxml2`_ >= v2.9.1: Required XML processing C
library for ``lxml``.
* `xlrd`_ >= v0.9.2: XLSX library for parsing STIX Profiles.
.. _Python: http://python.org/download
.. _lxml: http://lxml.de/index.html#download
.. _libxml2: http://www.xmlsoft.org/downloads.html
.. _xlrd: https://pypi.python.org/pypi/xlrd
For a Windows installer of lxml, we recommend looking here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
The **STIX Document Validator** supports Python 3.8+.
Installation
------------
The recommended method for installing the **STIX Document Validator** is via
``pip``.
::
$ pip install stix-validator
This will install the ``sdv`` package into your Python installation's
``site-packages`` and four scripts found under ``sdv/scripts`` on your ``PATH``.
How To Use
----------
The **STIX Document Validator** bundles four scripts: ``stix_validator.py``,
``profile_to_sch.py``, ``profile_to_xslt.py``, and ``cybox_validator.py``,
STIX Validation
"""""""""""""""
The ``stix_validator.py`` script can can validate a STIX XML document against
STIX schemas, STIX Best Practices, and STIX Profiles.
**NOTE:** The STIX Profile validation should be considered **experimental.**
**Validate using bundled schemas**
.. code-block:: bash
$ stix-validator <stix_document.xml>
**Validate using schemaLocation**
.. code-block:: bash
$ stix-validator --use-schemaloc <stix_document.xml>
**Validate using non-bundled schemas**
.. code-block:: bash
$ stix-validator --schema-dir </path/to/schemas> <stix_document.xml>
**NOTE:** If you are trying to validate a STIX document from a checked-out
copy of STIX schema repository, make sure you have also cloned the CybOX
schema submodule with ``git submodule init`` and ``git submodule update``.
**Validate a directory of STIX documents**
.. code-block:: bash
$ stix-validator </path/to/stix_dir>
**Validate multiple files and/or directories**
.. code-block:: bash
$ stix-validator <one.xml> <two.xml> <directory_of_files> ...
**Check "best practice" guidance**
.. code-block:: bash
$ stix-validator --best-practices <stix_document.xml>
**Validate using STIX Profile**
.. code-block:: bash
$ stix-validator --profile <stix_profile.xlsx> <stix_document.xml>
STIX Profile to Schematron Conversion
"""""""""""""""""""""""""""""""""""""
The ``profile_to_sch.py`` script performs a conversion from a valid STIX profile
to schematron.
.. code-block:: bash
$ profile-to-sch <valid_stix_profile.xlsx>
Schematron output is sent to stdout.
STIX Profile to XSLT Conversion
"""""""""""""""""""""""""""""""
The ``profile_to_xslt.py`` script performs a conversion from a valid STIX profile
to XSLT.
.. code-block:: bash
$ profile-to-xslt <valid_stix_profile.xlsx>
XSLT output is sent to stdout.
CybOX Validation
""""""""""""""""
The ``cybox_validator.py`` script can perform CybOX XML Schema validation.
**Validate using bundled schemas**
.. code-block:: bash
$ cybox-validator <cybox_document.xml>
**Validate using schemaLocation**
.. code-block:: bash
$ cybox-validator --use-schemaloc <cybox_document.xml>
**Validate using non-bundled schemas**
.. code-block:: bash
$ cybox-validator --schema-dir </path/to/schemas> <cybox_document.xml>
**Validate a directory of CybOX documents**
.. code-block:: bash
$ cybox-validator </path/to/cybox_dir>
**Validate multiple files and/or directories**
.. code-block:: bash
$ cybox-validator <one.xml> <two.xml> <directory_of_files> ...
All STIX and CybOX Documents?
-----------------------------
The **STIX Document Validator** bundles XML schemas with it, which
includes all STIX (v1.0 through v1.2.1) and CybOX (2.0 through v2.1) schema
files. If a document includes instances of schematic constructs defined
outside of the STIX or CybOX languages, a user must point the
**STIX Document Validator** scripts at those schemas in order to validate.
To use schemas other than those bundled with the **STIX Document Validator**
use the ``--schemas-dir`` flag to pass in a path to a schema directory.
Common Libxml2 Error
--------------------
Users often report an error which looks something like the following:
::
Fatal error occurred: local union type: A type, derived by list or union, must have the
simple ur-type definition as base type, not '{http://cybox.mitre.org/common-2}(NULL)'., line 350
This error is caused by an insufficient version of libxml2 being installed
on the system. The **STIX Document Validator** requires ``libxml2`` v2.9.1 at
a minimum and is not guaranteed to work properly with earlier versions.
To see what version of libxml2 you have installed, execute the
``xml2-config --version`` command and make sure you are running at least v2.9.1.
