How do I get the JSON from a script tag of an HTML page?

Question

I have the following text that I parsed from a script tag of an HTML page:

var bnh = {
        bootstrap: {},
        hashedFileNameMap: {"css/main.a.css":"css/main.a-ce49f3c1.css","css/main.css":"css/main-d498c649.css","js/main.a.js":"js/main.a-7daba1f6.js","js/main.js":"js/main-94432af3.js"},
        permalinkUrl: null,
        initialURL: location.href,
        initialModuleID: 'home',
        initialContent: '',
        utils: {},
        queue: {},

Is there a way for me to somehow parse this text so that I can load only the "config" JSON portion of this text?

Answer 1

A quick and dirty way to do this would be a simple regex to grab the config portion of your string and load() it into Json .

import json
string = '''...'''
config = json.loads(re.search(r'(?<=config: ).*(?=,\n)', string).group())

config['appleSignInClientId']
#'com.bhphotovideo.signin'
