Android Question Extract Number from alphanumeric string

[Kiran Raotole]

My string = "AND051"

How extract number from this string?

like new variable = 051 / 51

 

[Erel]

Dim s As String = "AND051"
Dim m As Matcher = Regex.Matcher("\d+", s)
If m.Find Then
   Dim number As Int = m.Match
   Log(number)
End If

https://regex101.com/ is good for exploring regular expressions (and for building them, too ;-) eg:

Less polished but also useful: https://b4x.com:51041/regex_ws/index.html

I like that it provides the code.

 

[trepdas]

Dim s As String = "AND051"
Dim m As Matcher = Regex.Matcher("\d+", s)
If m.Find Then
   Dim number As Int = m.Match
   Log(number)
End If

How would I delete the numbers from the strings and keep only the "AND" ?

oldstring = "AND051"
newstring = "AND"

You should never post questions in old threads.

In your case, you can also use the replace function

    Dim s As String = "AND051"
    Log(Regex.Replace("\D",s,"")) '  replace all non digit char by nothing -> "051"
    Log(Regex.Replace("\d",s,"")) ' replace all digit char by nothing -> "AND"
