recover all line from an attribute in a database in json

Question

To simplify my problem, I have a base in json, and I recover all of my lines of json to put informations in a base. It seems easy for moments, but problem is that my json is not correctly written

So i did a code to recover all my json lines, but it doesn't work on all lines, like "biographie".

I show you

{"name": "Nazamiu0304 Rau0304majiu0304", "personal_name": "Nazamiu0304 Rau0304majiu0304", "last_modified": {"type": "/type/datetime", "value": "2008-08-20T18:00:41.270799"}, "key": "/authors/OL1001461A", "type": {"key": "/type/author"}, "revision": 2}
{"name": "Nazamiu0304 Rau0304majiu0304", "personal_name": "Nazamiu0304 Rau0304majiu0304", "last_modified": {"type": "/type/datetime", "value": "2008-08-20T18:00:41.270799"}, "key": "/authors/OL1001461A", "type": {"key": "/type/author"}, "revision": 2}

you see, you have name,personal name ...

sometimes you have other informations,

{"bio": {"type": "/type/text", "value": "> "Eversley, William Pinder, B.C.L. Queen's Coll., Oxon, M.A., a member of the South-eastern circuit, reporter for Law Times in Queen's Bench division, a student of the Inner Temple 14 April, 1874 (then aged 23), called to the bar 25 April, 1877 (eldest son of William Eversley, Esq., of London); born u2060, 1851. rn> rn> 7, King's Bench Walk, Temple, E.C." rn> ...[in Foster's _Men at the Bar_][1]rnrnrn  rnrn[1]: https://en.wikisource.org/wiki/Men-at-the-Bar/Eversley,_William_Pinder "Men at the Bar""}, "name": "William Pinder Eversley", "created": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "death_date": "1918", "photos": [6897255, 6897254], "last_modified": {"type": "/type/datetime", "value": "2018-07-31T15:39:07.982159"}, "latest_revision": 6, "key": "/authors/OL1003081A", "birth_date": "1851", "personal_name": "William Pinder Eversley", "type": {"key": "/type/author"}, "revision": 6}


{"name": "Valerie Meyer", "personal_name": "Valerie Meyer", "last_modified": {"type": "/type/datetime", "value": "2008-08-20T18:22:33.63997"}, "key": "/authors/OL1004062A", "type": {"key": "/type/author"}, "revision": 2}

You can see i have a lot of problem with the element "bio": because he is not written correctely at all, the quota are not interpreted correctely and "<" too so I got this code to change the structure of bio to exploit it.

Here my code to change structure of bio

import re
import json
import pprint


bio_regex = re.compile(
    r"""
("bio":\s*{)   # bio field start
(.*?)          # content
(},)           # bio field end
(?=\s*(?:"\w+"|}))  # followed by another one or the json end
""",
    flags=re.VERBOSE | re.DOTALL)

value_regex = re.compile(
    r"""
("value":\s*")   # value field start
(.*?)            # content
("\s*\Z)         # value field end + end of string
""",
    flags=re.VERBOSE | re.DOTALL)


def normalize_value(mo):
    start, content, end = mo.group(1, 2, 3)
    content = content.replace('"', '\\"')
    return start + content + end


def normalize_bio(mo):
    start, content, end = mo.group(1, 2, 3)
    content = value_regex.sub(normalize_value, content)
    return start + content + end

messy_json = """

  "bio":{ 
    "type":"/type/text",

result = bio_regex.sub(normalize_bio, messy_json)
obj = json.loads(result)

Here is the result:

{'bio': {'type': '/type/text',
         'value': '> "Eversley, William Pinder, B.C.L. Queen\'s Coll., Oxon, M.A., a member of the '

                  'the Inner Temple 14 April, 1874 (then aged 23), called to the bar 25 April, 1877 (eldest '

 'personal_name': 'William Pinder Eversley',
 'photos': [6897255, 6897254],
 'revision': 6,
 'type': {'key': '/type/author'}}

The problem here is that this script is good if I put my entire line in my code, but i would like to recover my 1000000 lines of bio with the good structure, I can't do that 1 per 1, I tried a lot of thing with a loop to recover 1 per 1 but it puts me always an error, I need know how recuperate it witch a loop . I need upgrade my code to take all lines of database from line bio and not only 1 per 1

Thanks in advance and thanks to listen me!

For exemple, I wanted say that : I have a file , openlibraryjson.json :

with these lines :

{"name": "Ismail Ibrahim Dr.", "title": "Dr.", "personal_name": "Ismail Ibrahim", "last_modified": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "key": "/authors/OL100304A", "type": {"key": "/type/author"}, "revision": 1} {"bio": {"type": "/type/text", "value": "> "Eversley, William Pinder, BCL Queen's Coll., Oxon, MA, a member of the South-eastern circuit, reporter for Law Times in Queen's Bench division, a student of the Inner Temple 14 April, 1874 (then aged 23), called to the bar 25 April, 1877 (eldest son of William Eversley, Esq., of London); born u2060, 1851. rn> rn> 7, King's Bench Walk, Temple, EC" rn> ...[in Foster's Men at the Bar ][1]rnrnrn rnrn[1]: https://en.wikisource.org/wiki/Men-at-the-Bar/Eversley,_William_Pinder "Men at the Bar""}, "name": "William Pinder Eversley", "created": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "death_date": "1918", "photos": [6897255, 6897254], "last_modified": {"type": "/type/datetime", "value": "2018-07-31T15:39:07.982159"}, "latest_revision": 6, "key": "/authors/OL1003081A", "birth_date": "1851", "personal_name": "William Pinder Eversley", "type": {"key": "/type/author"}, "revision": 6} {"name": "Valerie Meyer", "personal_name": "Valerie Meyer", "last_modified": {"type": "/type/datetime", "value": "2008-08-20T18:22:33.63997"}, "key": "/authors/OL1004062A", "type": {"key": "/type/author"}, "revision": 2} {"bio": {"type": "/type/text", "value": "[Deutsch] Deutscher Orientalist und Theologe.rn[English] German orientalist and biblical scholar."}, "name": "August Dillmann", "links": [{"url": " http://de.wikipedia.org/wiki/August_Dillmann ", "type": {"key": "/type/link"}, "title": "Wikipedia (Deutsch)"}, {"url": " http://en.wikipedia.org/wiki/August_Dillmann ", "type": {"key": "/type/link"}, "title": "Wikipedia (English)"}], "personal_name": "August Dillmann", "death_date": "4 July 1894.", "alternate_names": ["Christian Friedrich August Dillmann", "Ch. FA Dillmann", "Friedrich August Dillmann", "FA Dillmann", "Augustus Dillmann", "August Dillmann", "A. Dillmann"], "created": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "photos": [6676274], "last_modified": {"type": "/type/datetime", "value": "2017-03-31T12:45:57.925108"}, "latest_revision": 8, "key": "/authors/OL1179559A", "birth_date": "25 April 1823", "revision": 8, "type": {"key": "/type/author"}, "remote_ids": {"viaf": "45046685", "wikidata": "Q75216"}} {"last_modified": {"type": "/type/datetime", "value": "2008-04-01T03:28:50.625462"}, "type": {"key": "/type/author"}, "name": "Physikertagung (1966 Munich, Germany)", "key": "/authors/OL1179696A", "revision": 1}

I would like take only line bio and treat them to put them functionnal, for it I tried to open my file, and I Treat name,personal_name ... with a loop, it works but not for bio because it's not written correctly, so I skip bio in my script for moment But now i would like to don't skip bio and work with bio in the same way that for name,personal_name ...

Like it :

with open('openlibrary(3).json') as file: for i in range(101): line = file.readline() if "bio" in line: line.replace("\\'", "'") continue content_json = json.loads(line) if not "personal_name" in line: #print('NULL') ligne.append("NULL") continue try: #print(content_json['name']) ligne.append(content_json['personal_name']) except IndexError: print('NULL') if not "personal_name" in line: # print('NULL') personal_nom.append("NULL") continue try: # print(content_json['name']) personal_nom.append(content_json['personal_name']) except IndexError: print('NULL')

I just put some code here to show a bit what i did for name,personal_name...

Thanks you again for listen me and aswer me !!!!
