@Phrancis I didn't want to be impolite though. I was joking but it came out a bit wrong I guess. I actually like "Monkevening" as it considers us Ozies too. :)
@Mehrad Just so you know... we tend to say "Monking" at all hours. It's 7pm where I'm at. I think @Phrancis is the same time zone as me (roughly) and he's saying "Monking" even though it's evening...
In computer programming, an anonymous function (also function literal or lambda abstraction) is a function definition that is not bound to an identifier. Anonymous functions are often:
passed as arguments to higher-order functions, or
used to construct the result of a higher-order function that needs to return a function.
If the function is only used once, or a limited number of times, an anonymous function may be syntactically lighter than using a named function. Anonymous functions are ubiquitous in functional programming languages and other languages with first-class functions, where they fulfill...

I mean, who though it was a good idea to use a quote for comments? And have the first character of each keyword uppercase, almost implying that they're classes? Ahhhg.

Does the structure of this regex is correct?
\[{1}+[\w]+\-?[\w]*(\=|\~|\||\^|\$|\*)*\"*?[\w]*(\-|\/)*[\w]*\.*[a-z]*\"*?\]{1}
I want to use it to find selectors of this kind:
[class="test"]

@EthanBierlein This one is actually funny because I changes my IDE syntax coloring to display semicolons as navy dark blue purposefully to match the black background so I don't have to see them. Often turns out regretting but code inspection helps me out most of the time.
So I have a solution but it fails the performance for two tests. How can I speed it up?

This is actually something I wanted to avoid. Putting all functions into single file is not acceptable for me. It's really hard to do code reviews on such file and. Apart from that, I want to keep certain directory structure among my functions.

Additionally, if you actually have a working program (even though it may only work for smaller problems), then Code Review is a better place to get help improving it, but bear in mind that they will complain about the exact same things I did in my previous comment, the question is very unclear, so crossposting or reposting it there won't help. — Lasse V.

@JeroenVannevel I downloaded VSDiagnostics earlier, when a colleague came over. I was showing him something and used the string.Empty converter. He asked what it was, and when I demonstrated, was pleasantly surprised and installed it himself.
Stackoverflow also requires you to post your effort. Unlike codereview.stackexchange.com your code/algorithm/implementation does not have to work as desired. This also helps to answer question at your skill level. — Margus13 secs ago
