Android Question Work with substring

[stp]

How do i get from

https://www.test.com/mysite/test.html

test.html ?

 

[amykonio]

Are you looking for something like that?

Dim s As String = $"https://www.test.com/mysite/test.html"$
    
Dim result() As String = Regex.Split("/", s)

If result.Length > 0 Then
    Log(result(result.Length - 1))
End If

Or like this:

    Private s As String = "https://www.test.com/mysite/test.html"
    Private i As Int
    Private r As String
    i = s.LastIndexOf("/")
    r = s.SubString(i + 1)
    Log(r)

other;
Last segment of the route before a possible query string

    Dim Text As String = $"https://www.test.com/mysite/test.html"$
    Dim Pattern As String = $"\/([^\/?#]+)(?:[?#]|$)"$
    Dim Matcher1 As Matcher = Regex.Matcher(Pattern,Text)
    If Not (Matcher1.Find) Then Return
    Log(Matcher1.Group(1))

Or even:

Dim S As String = "https://www.test.com/mysite/test.html"
Log(File.GetName(S))

 

[stevel05]

Log(File.GetName(S))

ooops My Bad. File.GetName doesn't exist in B4a. Sorry.

 

[aeric]

Dim S As String = "https://www.test.com/mysite/test.html"
Log(S.Replace("https://www.test.com/mysite/", ""))

 

[stevel05]

ooops My Bad. File.GetName doesn't exist in B4a. Sorry.

In which case my fallback would be Klaus's answer.

 

[amykonio]

ooops My Bad. File.GetName doesn't exist in B4a. Sorry.

While it may not work in b4a, it's a good answer for those using b4j.

You can use this sub

FileUtil SUBs

SubName: GetFilename Description: Gets the Filename of Image or Page from Path Sub GetFilename(fullpath As String) As String Return fullpath.SubString(fullpath.LastIndexOf("/") + 1) End Sub ' ' Example Log(GetFilename("http://www.domain.tld/SomePage.html")) ' -> SomePage.html Tags...
