Question

我正在尝试从RSS链接中抓取一些数据。我刚刚开始这个项目；以后会有一些带有GUI的东西。我无法删除某些我不想在特定行上显示的内容。在这种情况下，我希望最后一个“ at”之后的所有内容都消失，以便仅显示职位。

我尝试用空字符串替换“ at”字符串的实例，但是这也会从字符串中删除“ a”后跟“ t”的任何实例。我想我必须建立一个用空格隔开的单词映射表（例如，strings.Fields（）？），然后设置一个for循环，以替换从单词开始的整个字符串。

代码：

package main

import (
    "encoding/xml"
    "fmt"
    "log"
    "net/http"
    "strings"
)

type JobInfo struct{
    Title string `xml:"title"`
    Location string `xml:"location"`
    Company string `xml:"a10:author"`
    PostDate string `xml:"pubDate"`
    Description string `xml:"description"`
}

type Channel struct{
    Title string `xml:"title"`
    Link  string `xml:"link"`
    Desc  string `xml:"description"`
    Items []JobInfo `xml:"item"`
}

type Rss struct {
    Channel Channel `xml:"channel"`
} 

func main() {
    resp, err := http.Get("https://stackoverflow.com/jobs/feed?l=Bridgewater%2c+MA%2c+USA&u=Miles&d=100")
    if err != nil{
        log.Fatal(err)
        return
    }
    defer resp.Body.Close()

    rss := Rss{}

    decoder := xml.NewDecoder(resp.Body)
    err = decoder.Decode(&rss)
    if err != nil{
        log.Fatal(err)
        return
    }

    fmt.Printf("%v\n", rss.Channel.Title)
    for i, item := range rss.Channel.Items{
        fmt.Printf("%v. Job Information:\n", i+1)
        fmt.Printf("Title: %v\n", item.Title)
        fmt.Printf("Location: %v\n", item.Location)
        fmt.Printf("Company: %v\n", item.Company)
        postdate := strings.Replace(item.PostDate, "Z", "", -1)
        fmt.Printf("Post Date: %v\n", postdate)
        fmt.Printf("Description: %v\n", item.Description)
    }
}

在“标题”字段中，只能说：高级Web工程师

稍后我将在说明中找出公司名称和字节串，但是如果有人对此有任何输入，将不胜感激！

希望这对您有用

   fmt.Println(item.Title[:strings.LastIndex(item.Title," at ")])

如何删除仅从特定单词的最后一个实例开始的整个字符串？
