在javascript中使用REGEX分割字符串

Question

I'm trying to parse string into 5 parts. For example:

var str1 = '#<SYSTEM list-of / asdf-finalizers-20140826-git / quicklisp 2014-08-26>'

// filter is used to remove empty strings from the returned array
str1.split(/[ #<>/]/).filter(function(n) { return n !== ''; });

// str1[0] -> SYSTEM
// str1[1] -> list-of
// str1[2] -> asdf-finalizers-20140826-git
// str2[3] -> quicklisp
// str2[3] -> 2014-08-26

But the problem is, I can't parse the strings containing slash in the middle of words For example,

#<SYSTEM asdf-finalizers-test/1 / asdf-finalizers-20140826-git / quicklisp 2014-08-26>

What is the correct regex to parse the word asdf-finalizers-test/1 ? I tried these but failed.

/[(\\s\\/\\s) #<>]/ , /[(?:\\s\\/\\s) #<>]/ , /[ #<>]|(\\s\\/\\s)/

Answer 1

The following seems to work:

/ \/ |[ #<>]/

'#<SYSTEM asdf-finalizers-test/1 / asdf-finalizers-20140826-git / quicklisp 2014-08-26>'.split(/ \/ |[ #<>]/).filter(Boolean)
> [ 'SYSTEM',
    'asdf-finalizers-test/1',
    'asdf-finalizers-20140826-git',
    'quicklisp',
    '2014-08-26' ]

Answer 2

You could use a negative lookahead to not to split according to / when it is followed by a word character.

> var s = "#<SYSTEM asdf-finalizers-test/1 / asdf-finalizers-20140826-git / quicklisp 2014-08-26>"
> s.split(/[ #<>]|\/(?!\w)/).filter(function(n) { return n !== ''; });
[ 'SYSTEM',
  'asdf-finalizers-test/1',
  'asdf-finalizers-20140826-git',
  'quicklisp',
  '2014-08-26' ]
