I have very odd question that involves JSON Returned to me by D&B Matching API.
The Problem I am facing is that there are this very odd formatted keys
ReliabilityText":{
"#DNBCodeValue":9092,
"$":"Actual"
}
I want to replace the '#' and '$' characters with a simple text.
I thought of solution using Regular expression, but I couldn't find any solution so far.
Thing that I forgot to mention is that I am using Salesforce APEX to run the code.
Thank you in advance!

I am currently trying to format a JSON object using LabVIEW and have ran into the issue where it adds additional quotation marks invalidating my JSON formatting. I have not found a way around this so I thought just formatting the string manually would be enough.
Here is the JSON object that I have:
{
"contentType":"application/json",
"content":{
"msgType":2,
"objects":"["cat","dog","bird"]",
"count":3
}
}
Here is the JSON object I want with the quotation marks removed.
{
"contentType":"application/json",
"content":{
"msgType":2,
"objects":["cat","dog","bird"],
"count":3
}
}
I am still not an expert with regex and using a regex tester I was only able to grab the "objects" and "count" fields but I would still feel I would have to utilize substrings to remove the quotation marks.
Example I am using (would use a "count" to find the start of the next field and work backwards from there)
"([objects]*)"
Additionally, all the other Regex I have been looking at removes all instances of quotation marks whereas I only need a specific area trimmed. Thus, I feel that a specific regex replace would be a much more elegant solution.
If there is a better way to go about this I am happy to hear any suggestions!
Your question suggests that the built-in LabVIEW JSON tools are insufficient for your use case.
The built-in library converts LabVIEW clusters to JSON in a one-shot approach. Bundle all your data into a cluster and then convert it to JSON.
When it comes to parsing JSON, you use the path input terminal and the default type terminals to control what data is parsed from a JSON string.
If you need to handle JSON in a manner similar to say JavaScript, I would recommend something like the JSONText Toolkit which is free to use (and distribute) under the BSD licence. This allows more complex and iterative building of JSON strings from LabVIEW types and has text-path style element access along with many more features.
The Output controls from both my examples are identical - although JSONText provides a handy Pretty Print vi.
After using a regex from one of the comments, I ended up with this regex which allowed me to match the array itself.
(\[(?:"[^"]*"|[^"])+\])
I was able to split the the JSON string into before match, match and after match and removed the quotation marks from the end of 'before match' and start of 'after match' and concatenated the strings again to form a new output.
While upgrading Django I noticed that the html escape function used to translate an apostrophe into ' whereas it now translates it into '. I understand the old value is the HTML code and the new value is the hex code. The change seems to have come about because Django used to do the translation itself but now hands it off to python's html module.
My question is, are these functionally equivalent? Are there any case where I would need to worry about this change?
Also, in case I am not asking the right questions, can anyone direct me to what I should read to understand why these 2 types of codes exist and how they are used?
I'm using Screaming Frog as a way to extract data from a Json generated from an URL.
The Json generated is this form :
{"ville":[{"codePostal":"13009","ville":"VAUFREGE","popin":"ouverturePopin","zoneLivraison":"1300913982","url":""},{"codePostal":"13009","ville":"LES BAUMETTES","popin":"ouverturePopin","zoneLivraison":"1300913989","url":""},{"codePostal":"13009","ville":"MARSEILLE 9EME ARRON","popin":"ouverturePopin","zoneLivraison":"1300913209","url":""}]}
I'm using this regex in Custom > Extraction in Screaming Frog as a way to extract the values of "codePostal".
"codePostal":".*?"
Problem is it doesn't extract anything.
When I test my regex in regex101, it seems correct.
Do you have any clue about what is wrong ?
Thanks.
Regards.
Have you tried to save the output to understand what ScreamingFrog sees? It doesn't matter - not at the beginning - whether your RegEx works.
That said, don't forget that SF is a Java based tool hence it is the engine used by the reg ex, so make sure you test your regular expressions with the correct dialect.
You need to specify group extractors enclosed in parentheses. For instance in your example, you need to have ("codePostal":".*?") as extractor.
In addition if you simply want to extract the value, you could use the following instead.
"codePostal":"(.*?)"
It's not a problem with your Regular Expression. It seems to be that the problem is with the Content Type. ScreamingFrog isn't properly reading application/JSON content types for scraping. Hopefully they will fix this bug.
I have the following text strings:
"Name":"John"}]
"Age":36
"Address":"ABC,PQR234[]/.,#ANYCHARACTERS"
"Gender":null
I need to get two groups (key value pair) from this such that the output would be only:
Key|Value
Name|John
Age|36
Address|ABC,PQR234[]/.,#ANYCHARACTERS
The requirement is to have a single regex to grab everything in the double quotes if the double quotes are present. If not, take the value without the quotes.
In our example above, 36 and null are the one without the quotes and they need to be captured as well.
I have tried a lot but have failed to do so.
UPDATE:
I don't know why I am getting down votes for this question. Yes this is JSON that I am trying to parse but there is a reason behind why I am doing this and not using any document parser.
I am supposed to use Talend for getting a dynamic JSON converted into Key Value Pair. What I mean by dynamic is the fields of the JSON can vary and hence I do not have a fixed schema and hence cannot use a document parser (which demands a fixed structure of JSON). I am devising a solution to get around this using Normalizer (on comma) and then extracting the key value pair which will be in double quotes using Regular Expressions. I tried many things on my own and since I am not an expert in Regular expressions, I have come here to get inputs.
If you know any better solution to this, I would be very happy to get your inputs.
How about this?
/"?([^\n"]*)"?:"?([^\n"]*)"?/

I am posting a form and one of the field values has a ":" and that is causing an issue
is there any correct way to be able to post this string;

You can use percent encoded version of colon "%3A"
Lots of libraries will have a method to process this, for example in ASP.NET if you do a UrlEncode that should get changed to a %3A, when you need to use it just do a UrlDecode on the string.

If you are not using any library that has this type of functionality then you can easily build your own little parsing function that will replace common characters with their HTML character code equivalent.
