Android Question Easy way to get each url on each line ( regex maybe ? )

[tufanv]

Hello,

I have a string like this:

/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/chyusc: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/7tyskq: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/bpjeu5: Win.Trojan.MSShellcode-7 FOUND
/var/www/xx.yy.com/public_html/files/q766jv: Win.Trojan.MSShellcode-7 FOUND
/var/www/xx.yy.com/public_html/files/lhie42: Doc.Malware.Valyria-6728957-0 FOUND

This string may be 100 lines or 6 lines it changes every day, I need to get the links of each line after files/ . For example for this string i need to get each link : qjax83,chyusc,7tyskq etc.. Is there an easy way to get these ? I tried to use substring etc but it is not optimal. Maybe possible with regex ?

Thanks

SubString2 is enough.

Dim Text As String = "/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND"
Dim Link as String = Text.SubString2(37, 43)

yes but the url can change dynamically(path to file) so the positions can change..

Use Index of to search the significative characters (position), like ":" and LastIndexOf for last "/"

 

[LucaMs]

    Dim Text As String = "/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND"
    Dim StartPos, EndPos As Int
    StartPos = Text.LastIndexOf("/") + 1
    EndPos = Text.IndexOf(":")
    Dim Link As String = Text.SubString2(StartPos, EndPos)
    Log("link " & Link)

 

[LucaMs]

Dim Text As String = "/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND"
Log(GetLink(Text))


Sub GetLink(Text As String) As String
    Dim StartPos, EndPos As Int
    StartPos = Text.LastIndexOf("/") + 1
    EndPos = Text.IndexOf(":")
    Return Text.SubString2(StartPos, EndPos)
End Sub

More shortly (I don't like it very much):

Sub GetLink(Text As String) As String
    Return Text.SubString2(Text.LastIndexOf("/") + 1, Text.IndexOf(":"))
End Sub

 

[tufanv]

Dim Text As String = "/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND"
Log(GetLink(Text))


Sub GetLink(Text As String) As String
    Dim StartPos, EndPos As Int
    StartPos = Text.LastIndexOf("/") + 1
    EndPos = Text.IndexOf(":")
    Return Text.SubString2(StartPos, EndPos)
End Sub

Thanks for the example, if it is 1 line it can be done but for multiple lines, it need a more complicated code to get for each line. Am I missing stg ?

Well, I based my code on your examples, I don't know what strings you will have.

Oh, in your first post is it a single string?

If so:

Dim Text As String = _
$"/var/www/xx.yy.com/public_html/files/qjax83: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/chyusc: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/7tyskq: Win.Trojan.B-468 FOUND
/var/www/xx.yy.com/public_html/files/bpjeu5: Win.Trojan.MSShellcode-7 FOUND
/var/www/xx.yy.com/public_html/files/q766jv: Win.Trojan.MSShellcode-7 FOUND
/var/www/xx.yy.com/public_html/files/lhie42: Doc.Malware.Valyria-6728957-0 FOUND
"$  

Dim lstTexts As List = Regex.Split("/var", Text)
For Each Txt As String In lstTexts
    If Txt.Length > 0 Then
        Log(GetLink(Txt))
    End If
Next

Sub GetLink(Text As String) As String
    Return Text.SubString2(Text.LastIndexOf("/") + 1, Text.IndexOf(":"))
End Sub

Yes, I used regex.split for each line now! works greate . Thanks Luca !
