Remove all articles and other strings from a string using Go?
Is there any method in Go or having regular expression that it will remove only the articles used in the string?
I have tried below code that will do it but it will also remove other words from the string I'm showing the code below:
removalString := "This is a string"
stringToRemove := string{"a", "an", "the", "is"}
for _, wordToRemove := range stringToRemove {
removalString = strings.Replace(removalString, wordToRemove, "", -1)
}
space := regexp.MustCompile(`s+`)
trimedExtraSpaces := space.ReplaceAllString(removalString, " ")
spacesCovertedtoDashes := strings.Replace(trimedExtraSpaces, " ", "-", -1)
slug := strings.ToLower(spacesCovertedtoDashes)
fmt.Println(slug)

In this It will remove the is which is used in the this.
The Expected output is this-string
regex string go

If your request is for an existing implementation, that is off-topic, as resource requests are not allowed here. If your question is how to improve or fix your current code, you need to be more specific: What problems are you facing? What help do you need?

You can use strings.Split and strings.Join plus a loop for filtering and then building it together again:
removalString := "This is a string"
stringToRemove := string{"a", "an", "the", "is"}
filteredStrings := make(string, 0)
for _, w := range strings.Split(removalString, " ") {
shouldAppend := true
lowered := strings.ToLower(w)
for _, w2 := range stringToRemove {
if lowered == w2 {
shouldAppend = false
break
}
}
if shouldAppend {
filteredStrings = append(filteredStrings, lowered)
}
}
resultString := strings.Join(filteredStrings, "-")
fmt.Printf(resultString)
Outpus:
this-string
Program exited.
