If it's a sign of anything, it's that you're probably reading too much into it...

Is this a sign? Do i have a chance to win on lottery or something?
I don't know... did you win the lottery when you had 318,813 points?

Can numbers be considered a palindrome also?

Thanks for all your down-votes, Bill.
I hope that satan-signed-reputation will help me winning on lottery.

Since Satan has made me the lottery, I guarantee you'll win.

So when you regex capture, you can specify capture groups like
(<identifier>?[A-Za-z_][A-Za-z0-9_]*)
what i can do with that is take those capture groups and make JSON fields out of them.
So then basically you can define a JSON object using a series of capture groups in regex, which you run over some text to scrape it.
Finally, you can take that and use it to create a web scraper that presents a facade of JSON objects based on regex scrape expressions.
Anyone seen anything like this already? And is it stupid? it's very simple, so i don't know. that can be good or bad.

Yes, I have seen and used Regex before... not sure what else you are suggesting you may have discovered here?
Also, JSON is just a string (it's basically a serialisation format). There are no fields or objects, perhaps you mean javascript objects?

conceptually a JSON object is
{
<fieldname>: <value>,
<fieldname>: <value>,
<fieldname>: <value>
}
A JSON array is
[
<element>,
<element>,
<element>
]
So now when I say these things you can know what I mean.
Now, furthermore when people use JSON they don't use it as a raw string, but normalized data.
My JSON engine, like every single one in existence, normalizes JSON into queryable objects.
For example, a JSON object (see above) may become an instance of a class implementing IDictionary<string, object>. (Json: A Fairly Powerful JSON Engine in a Small Package[^])
I'm sorry, I figured most people would know what I meant already.

No, that's not a JSON object, as the OP alluded to there isn't any such thing as a JSON object, there are simply objects (javascript objects, c# objects, it doesn't matter). The "N" in JSON is "notation" - what you posted above is how an object is represented in string form using the JSON format\standard.

I think you're being pedantic.

I don't mind if you say "JSON object", I know what you mean, but when someone clarifies your terminology and you talk down to them as if it is them that doesn't understand rather than you, then...yeah, I'mma gonna get real pedantic

I believe they talked down to me first, but maybe i misread the situation. It's early here and I shouldn't be up.

When working with JavaScript and JSON it's important to know that they are different. In my experience, there are a lot of people, especially those new to JavaScript, that don't realise they are different. This misunderstanding can lead to problems.
The reason I pointed it out to you is because you were speaking as if you didn't know they are different, and like I said, I think it's an important thing to be aware of... so I made you aware of it.
Also, being corrected about something isn't "talking down".

well like i said to F-ES Sitecore it's early here and I guess i misread the situation.
I apologize.

Fair enough. And don't worry, I wasn't offended, you are entitled to defend yourself as and when you feel the need to.

I'm glad you weren't. Don't mind me, I shouldn't even be up right now. Meh.

Well, it depends what you are trying to do with it. Regexes aren't exactly brilliant performance wise: Counting Lines in a String[^] - which makes sense when you think just how "general purpose" they are.
I'd suspect that a specific-to-JSON solution would be a damn sight more efficient.

if I'm scraping a web page I'm worried about network performance, not regex performance
short of being on a SAN, which there'd be no reason to scrape except legacy integration, the network IO will outshadow any potential Regex performance issues by a large margin.
So I'm not worried about that.
Adding: If it really became an issue I could switch over to a non-backtracking engine like the one I wrote in C#

I think there's a huge variation in performance between different regex engines.
Yes, it's never going to be lightning because of all the backward/forward matching going on but it can be a damned sight quicker than .NET would make it seem!
