Parser raises unhandled AttributeError in parse_edtf #32
Description
The parser fails with an unhandled AttributeError on the following: '7 Jun-14 Jul 1916'. It looks like the issue is that the lower and upper bounds are both lists. I'm expecting EDTFParseExceptions, but not Attribute errors.
Code to replicate: (edtf=4.0.1, python = 3.6)
import edtf
parsed_date_string = edtf.text_to_edtf('7 Jun-14 Jul 1916') # 'uuuu-06-07/1916-07-14'
parsed_date = edtf.parse_edtf(parsed_date_string) # [PartialUnspecified: 'uuuu-06-07']/[Date: '1916-07-14']
lower = parsed_date.lower_strict()
Exception thrown:
AttributeError Traceback (most recent call last)
~/Code/silo_indexer/.venv/lib/python3.6/site-packages/edtf/parser/parser_classes.py in _strict_date(self, lean)
350 try:
--> 351 r = self.lower._strict_date(lean)
352 if r is None:
AttributeError: 'list' object has no attribute '_strict_date'
During handling of the above exception, another exception occurred:
