查找给定文本中的所有选定单词

Question

我有下面的代码，我希望用户输入一些关键词，然后从这些词中找到给定字符串中存在的内容，但结果matches切片是一个长度等于要检查的文本的空切片 游乐场package mainimport (    "fmt"    "regexp")func main() {    p := []string{}    p = append(p, "engineer")    p = append(p, "doctor")    var skills string    for _, z := range p {        skills += `|` + z    }    fmt.Println(skills)    re := regexp.MustCompile(`(?i)` + skills)    matches := re.FindAllString("I'm an engineer not a doctor", -1)    fmt.Println(matches)    for i, j := range matches {        fmt.Println(i, j)    }}

Answer 1

感谢提供的评论，我得到的是：

package main

import (

    "fmt"

    "regexp"

    "strings"

)

func main() {

    p := []string{}

    p = append(p, "engineer")

    p = append(p, "doctor")

    p = append(p, "chemical (permit)")

    skills := strings.Join(p, "|")

    

    fmt.Println(skills)

    re := regexp.MustCompile(`(?i)` + skills)

    matches := re.FindAllString("I'm an engineer not a doctor who is getting chemical permits", -1)

    fmt.Println(matches, len(matches))

    for i, j := range matches {

        fmt.Println(i, j)

    }

}

输出是：

engineer|doctor|chemical (permit)

[engineer doctor chemical permit] 3

0 engineer

1 doctor

2 chemical permit
