由多个分隔符拆分字符串

Question

我想用空格分割字符串,,并'使用单个ruby命令.

1. word.split 将被白色空间分开;

2. word.split(",")将分裂,;

3. word.split("\'")将分裂'.

如何一次完成这三个？

Answer 1

word = "Now is the,time for'all good people"
word.split(/[\s,']/)
 => ["Now", "is", "the", "time", "for", "all", "good", "people"] 

Answer 2

正则表达式.

"a,b'c d".split /\s|'|,/
# => ["a", "b", "c", "d"]

Answer 3

这是另一个:

word = "Now is the,time for'all good people"
word.scan(/\w+/)
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]

Answer 4

您可以使用split方法和Regexp.union方法的组合,如下所示:

delimiters = [',', ' ', "'"]
word.split(Regexp.union(delimiters))
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]

你甚至可以在分隔符中使用正则表达式.

delimiters = [',', /\s/, "'"]
word.split(Regexp.union(delimiters))
# => ["Now", "is", "the", "time", "for", "all", "good", "people"]

该解决方案具有允许完全动态分隔符或任何长度的优点.
