Javascript Regex逗号分隔文本

Question

I have this string:

remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820,remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820

I want to match and extract strings separated with commas.

The result should be:

MATCH 1 
'remote:City|Vestavia Hills,AL' 
MATCH 2 
'remote:Citystate|Vestavia Hills' 
MATCH 3 
'395b5231539390675a7abe0751fc4820' 
MATCH 4 
'remote:City|Vestavia Hills,AL' 
MATCH 5 
'remote:Citystate|Vestavia Hills' 
MATCH 6 
'395b5231539390675a7abe0751fc4820'

I have this regex:

(remote:[a-zA-Z]+\|[^\,]+|[a-f0-9]{32})

but those cities which have state 'AL' (separated with comma) are separated incorrectly.

Possible solution:

I was thinking of doing something like this - remote:[a-zA-Z]+\\|.* - and end match on the comma which have after it self ( remote:[a-zA-Z]+\\|.* ) or md5 hash ( [a-f0-9]{32},? ).

Answer 1

You can fine-tune your regex into this lookahead based regex:

/(?:^|,)(.+?(?=,(?:[a-f0-9]{32}|remote:)|$))/igm

This will give 6 captured groups as you're expecting.

Updated RegEx Demo

(?:^|,)                 # Match line start or comma
(                       # captured group #1 start
   .+?                  # match 1 or more of any character (lazy)
   (?=                  # lookahead start
      ,                 # match comma followed by
      (?:               # non-capturing group start
         [a-f0-9]{32}   # match hex digit 32 times
         |              # OR
         remote:        # match literal "remote:"
      )                 # non-capturing group end
      |                 # OR
      $                 # line end
   )                    # looakehad end
)                       # capturing group #1 end

Answer 2

([a-f0-9]{32}|remote:[^|]+\|[^,]+(?:,[A-Z]{2})?),?

This one is simpler to understand, I made a special optional sufix to the group, than can only be 2 uppcase letters after a comma.

Answer 3

With a single regex you might do as follows;

 var str = "remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820,remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820", arr = str.match(/(r.+?|[\\da-f]{32})(?=,?(remote|[\\da-f]{32}|$))/g); console.log(arr); 

Answer 4

One option is to use split of javascript:

 var str = "remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820,remote:City|Vestavia Hills,AL,remote:Citystate|Vestavia Hills,395b5231539390675a7abe0751fc4820"; var aux = str.split("remote"); var res = []; for (var i=1 ; i < aux.length ; i++){ res.push("remote" + aux[i]); }; console.log(res);
