# Schematron

cdef class Schematron(_Validator):
    u"""Schematron(self, etree=None, file=None)
    A Schematron validator.

Pass a root Element or an ElementTree to turn it into a validator.
    Alternatively, pass a filename as keyword argument 'file' to parse from
    the file system.

Schematron is a less well known, but very powerful schema language.  The main
    idea is to use the capabilities of XPath to put restrictions on the structure
    and the content of XML documents.  Here is a simple example::

>>> schematron = Schematron(XML('''
      ... <schema xmlns="http://www.ascc.net/xml/schematron" >
      ...   <pattern name="id is the only permitted attribute name">
      ...     <rule context="*">
      ...       <report test="@*[not(name()='id')]">Attribute
      ...         <name path="@*[not(name()='id')]"/> is forbidden<name/>
      ...       </report>
      ...     </rule>
      ...   </pattern>
      ... </schema>
      ... '''))

>>> xml = XML('''
      ... <AAA name="aaa">
      ...   <BBB id="bbb"/>
      ...   <CCC color="ccc"/>
      ... </AAA>
      ... ''')

>>> schematron.validate(xml)
      0

>>> xml = XML('''
      ... <AAA id="aaa">
      ...   <BBB id="bbb"/>
      ...   <CCC/>
      ... </AAA>
      ... ''')

>>> schematron.validate(xml)
      1

Schematron was added to libxml2 in version 2.6.21.  Before version 2.6.32,
    however, Schematron lacked support for error reporting other than to stderr.
    This version is therefore required to retrieve validation warnings and
    errors in lxml.
