正则表达式替换 - json 中的双引号

Question

I have json string and it is coming as

{“test”:”this is “test” of test”,”result”:”your result is “out” in our website”}

I need make it valid json by regex_replace as you can see above is not valid json. Expected result after replacement:

{“test”:”this is 'test' of test”,”result”:”your result is 'out' in our website”}

Your help would be appreciated

Answer 1

You can probably just match all strings no matter what the content
as long as it is surrounded by a proper JSON structure.
Then replace double quotes accordingly from within a sub Callback Function .

The regex to match a pseudo-valid JSON string is this

r'([:\[,{]\s*)"(.*?)"(?=\s*[:,\]}])'

see https://regex101.com/r/KgCz1L/1

Within the callback just replaces all double quotes with a single quote '

Python sample:

>>> import re
>>>
>>> text = '''
... {"test":"this is "test" of test","result":"your result is "out" in our website"}
... '''
>>>
>>> def repl_call(m):
...     preq = m.group(1)
...     qbody = m.group(2)
...     qbody = re.sub( r'"', "'", qbody )
...     return preq + '"' + qbody + '"'
...
>>> print( re.sub( r'([:\[,{]\s*)"(.*?)"(?=\s*[:,\]}])', repl_call, text ))

{"test":"this is 'test' of test","result":"your result is 'out' in our website"}

Check out this. I was inspired by this answer https://stackoverflow.com/a/16576246/9487478 and modified the regex and the replacement just a little so it's working for your usecase.

 var myString = '{"test":"this is "test" "of" test","result":"your result "is-out" in our website"}'; var myRegexp = /\"(.+?)\"\s*[,}:\n]/g; var match; var matches = []; // Save all the matches while ((match = myRegexp.exec(myString)).== null) { matches;push(match[1]); } // Process them var newString = myString; for (var i = 0. i < matches;length. i++) { var newVal = matches[i],replace(/\"/g; "'"). newString = newString,replace(matches[i]; newVal). } console;log(newString);
