No.
The trick is that you have a key-value pair KEY=VALUE, but the value can contain a "=", too (if it is escaped as ("\=").

Well, it's probably cheating, but:
(asdf)(?:\=)(237462\s123\sxdec\\\=123)(?:\s)(xdc)(?:\=)(12344)
will do it...

Matches the input, supplies the output!

It's probably still cheating, but you can "generalize" my last "solution" to this:
(\w+)(?:\=)([\w\s\\]+\=\w+)(?:\s)(\w+)(?:\=)(\w+) Which also works. It depends what the "important factors" in your input are, and one example isn't really enough...

Looking at your answer my brain just exploded, coffee and screws scattered everywhere. Always knew I had a screw loose, but so many?

One of the things I like about Expresso [^] is that you can tell it to ignore whitespace in the input string, so you can break the input into "phrases" - each on a signle line. If you do that:
(\w+)
(?:\=)
([\w\s\\]+\=\w+)
(?:\s)
(\w+)
(?:\=)
(\w+) It all looks easier:
(\w+) Any alphanumeric, one or more
(?:\=) Match an equals, but ignore it
([\w\s\\]+\=\w+) One or more alphanumeric, whitespace or '\' characters, a single equals sign,
then one or more alphanumeric again
(?:\s) Match whitespace, and ignore it
(\w+) Any alphanumeric, one or more again
(?:\=) Ignore another equals
(\w+) And finally any alphanumeric, one or more

Awesome thanks, I learned a few things from your explanation I hadn't known.
For what little RegEx I used to do I loved Expresso, it was a life saver in many instances.

I added another example, which blew your solution. Nevertheless, close you are.

Well if you are going to change the rules!
It's just a replacement of "\w" with "." in the final group:
(\w+)(?:\=)([\w\s\\]+\=\w+)(?:\s)(\w+)(?:\=)(.+)

OG's solution is nice but not exactly what you need...
First \w is declared in regex as [a-zA-Z0-9]. Are you sure your key can have numbers in it?
The value part can be anything (dot (.) not \w) but = must be escaped. Here OG is really far from it... (Sorry OG ).
After that can be an some whitespace and again a key-value pair, endlessly...And here the really catch! How do you know you got the next key-value pair? If value can have un-escaped whitespaces?
So - start again OG!!!
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Arrg, this has been bugging me on and off for a whole day. Why does it insist on always choosing the longest string match:
(\w+(?=\=))|((?<!\\)(?<=\=)(.+)((?=(\s\w+\=))))
|
|
|
|
|
Because you haven't told it not to!
Add a '?' after the appropriate '+' or '*' and it'all match the minimum it can.

Ah, that works, why didnt I think of that :facepalm:
|
|
|
|
|
I think im close but not quite:
((([a-zA-Z]|\d)+(?!\x5C)(?=\=))|(?<!\x5C)(?<=\=)(.*)(?=(\s\w+\=)))
|
|
|
|
|
Close, but not right yet.

Got it, a more general expression here:
(\w+(?=\=))|((?<!\\)(?<=\=)(.+?)((?=(\s\w+\=))|$))

This is why regex's should be banned from code bases that require maintenance.
OK in a search/replace context (editor's etc.), but surely we can come up with something better for actually code.

Text deserialization is a PITA - The code for that is not really easier to maintain.
