Hi all,

i'm trying to validate an OVAL (http://oval.mitre.org) xml document against it's schematron rules (http://oval.mitre.org/language/version5.7/ovaldefinition/schematron/oval-definitions-schematron.sch)

Following the manual (http://codespeak.net/lxml/validation.html) i wrote the following piece of code:

from lxml import etree

rule = open("oval-definitions-schematron.sch")
defs = open("oval.xml")

sct_doc = etree.parse(rule)
try:
    schematron = etree.Schematron(sct_doc)
except etree.SchematronParseError, e:
    print e.args
    print e.error_log
    print e.message

doc = etree.parse(defs)
print schematron.validate(doc)

but i got the following error(s):

Document is not a valid Schematron schema
oval-definitions-schematron.sch:34:0:ERROR:SCHEMASP:SCHEMAP_NOROOT: Expecting a pattern element instead of phase (repeated N times)
...
