Re: Help with regex for complicated key=value string

Points 1.-3. alone can be simply done with some negative look-behind,

Point 2 can't be done using just a look-behind if you can escape slashes as well as commas.

key1=\\\\\\value\\\\\\,key2=///value///

Point 2 can be done with: `split /(?:^\|[^\\])(?:\\\\)*\K,/ # 5.10 required` [download] But that's just point 2, it doesn't consider commas inside quotes.	[reply] [d/l]

That would be: `split /(?:$key_pat=)?$val_pat\K,/` [download] Read more... Test (547 Bytes) Using `split` means everything has to be parsed twice. Once to find the commas on which to split and once to find the composing terms. Update: Simplified pattern slightly.	[reply] [d/l] [select]
