Форма Regex json из html источника

Question

Я дошел до того, что мне не удалось переопределить значение json из источника html.

Источник html выглядит следующим образом:

<script data-csp-hash=""> window.__webpack_public_path__='https://renderer-assets.typeform.com/';
window.__webpack_nonce__='3088edaa602c001b5f6e1f31e3179422';
window.rendererAssets='["https://renderer-assets.typeform.com/vendors~libphonenumber~submission.c94d30638908af997673.js","https://renderer-assets.typeform.com/country-data.526012987a7e72182726.js","https://renderer-assets.typeform.com/form-container.98c74a2ac320736bdb16.js","https://renderer-assets.typeform.com/renderer.8282fd35106b77e43e2f.js","https://renderer-assets.typeform.com/submission.5d9a15e294b33a20ea2e.js","https://renderer-assets.typeform.com/vendors~form-container.b5fb128466f604baadba.js","https://renderer-assets.typeform.com/vendors~video.aa830e76dcc8735c9936.js","https://renderer-assets.typeform.com/video.45eca666f47b245e8fdb.js"]';
window.rendererData= {
    rootDomNode: 'root',
    form:     {

                "validations": {
                    "required": true
                }
                ,
                "type":"short_text"
            }

                "title":"EMAIL ADDRESS",
                "ref":"8860a4cf-71ec-4bfa-a2c7-934fd405f200",

            ],
            "_links": {
                "display": "link.com"
            }
        }
    ,
    messages: {
        "a11y.file-upload.remove":"Remove uploaded file",
    }
    ,
    trackingInfo: {
        "segmentKey": "9at6spGDYXelHDdz4r0cP73b3wV1f0ri", "accountId": 12587347, "accountLimitName": "Essentials", "userId": 12586030
    }
    ,
    stripe: null,
    showBranding: true,
    accessScheduling: {
        "closeScreenData": {
            "title":"This typeform isn't accepting new responses",
            "description":"",
            "brandingMottoText":"How you ask is everything",

, и я хочу очистить форму значение json, которая является этой частью:

{

            "welcome_screens":[ {
                "ref":"a13820db-af60-40eb-823d-86cf0f20299b",
                "title":"Yessir!",
                "properties": {
                    "show_button": true, "button_text": "Start"
                }
            }
            ],
            "thankyou_screens":[ {
                "ref":"default_tys",
                "title":"Done! Your information was sent perfectly.",
                "properties": {
                    "show_button": false, "share_icons": false
                }
            }
            ],
            "fields":[ {
                "id":"kxWycKljdtBq",
                "title":"FIRST NAME",
                "ref":"27f403f7-8c5b-4e18-b19d-1501e8f137ee",
                "validations": {
                    "required": true
                }
                ,
                "type":"short_text"
            }
            ,
            {
                "id":"WEXCnZ7EAFjN",
                "title":"LAST NAME",
                "ref":"a6bf6d83-ee37-4870-b6c5-779822290cde",
                "validations": {
                    "required": true
                }
                ,
                "type":"short_text"
            }
            ,
            {
                "id":"ButwoV1bTge5",
                "title":"EMAIL ADDRESS",
                "ref":"8860a4cf-71ec-4bfa-a2c7-934fd405f200",
                "properties": {
                    "description": "Note for stackoverflow!"
                }
                ,
                "validations": {
                    "required": true
                }
                ,
                "type":"email"
            }
            ],
            "_links": {
                "display": "link.com"
            }
        }

Я смог почти очистить его, используя этот

(?sm)^\s*form:\s*{(.*?)\n}$ #Not quite sure if this would work in Python however.

Однако моя проблема в том, что он продолжает очищать что после значения form , такого как messages, trackingInfo, stripe и т. д., и я просто хочу получить форму json и ничего больше.

Как я могу получить получить только регулярное выражение для form: json значения?

Answer 1

Вы можете попробовать этот метод:

data = '''....'''
data = re.findall("form\:[\S\s]*messages",data)[0]
data = re.sub("^form\:","",data)
data = re.sub("\,\n|\smessages","",data)
print data
