我想知道是否有任何方法可以轻松地在空格处拆分字符串,除非空格在引号内?
例如,更改
Foo bar random "letters lol" stuff
到
Foo
,bar
,random
和"letters lol"
stuff

想一想。您有一个逗号分隔值(CSV)文件格式RFC4180的字符串,但您的分隔符,外部引号对是空格(而不是逗号)。例如,
package main
import (
"encoding/csv"
"fmt"
"strings"
)
func main() {
s := `Foo bar random "letters lol" stuff`
fmt.Printf("String:\n%q\n", s)
// Split string
r := csv.NewReader(strings.NewReader(s))
r.Comma = ' ' // space
fields, err := r.Read()
if err != nil {
fmt.Println(err)
return
}
fmt.Printf("\nFields:\n")
for _, field := range fields {
fmt.Printf("%q\n", field)
}
}

输出:
String:
"Foo bar random \"letters lol\" stuff"
Fields:
"Foo"
"bar"
"random"
"letters lol"
"stuff"

您可以使用regex
这个(go playground)将涵盖引号内多个单词和数组中多个引用条目的所有用例:
package main
import (
"fmt"
"regexp"
)
func main() {
s := `Foo bar random "letters lol" stuff "also will" work on "multiple quoted stuff"`
r := regexp.MustCompile(`[^\s"']+|"([^"]*)"|'([^']*)`)
arr := r.FindAllString(s, -1)
fmt.Println("your array: ", arr)
}
输出将是:
[Foo, bar, random, "letters lol", stuff, "also will", work, on, "multiple quoted stuff"]
