How to remove Alphabets from Alphanumeric String ???

How to convert a Alphanumeric Input into a Numeric Output in Pega ? Is there any inbuilt OOTB Function in Pega that could be used in Property-Set ?

For Example, If Param.Input= "ABC123456789", then output should be "123456789".

Important Note*** : We don't have Standard pattern** here. Sometimes, the input might be "A12354987" or "AB123456789". So we cant use Substring function as well. :(

Please help , if you guys have any idea, please suggest.. how to convert a alphanumeric value into a numeric value ?

Hi Rama,

I just tried a sample code using the java replace all function with regular expression as follows,

String str = "a12334tyz78x";
str = str.replaceAll("[^\\d]", "");
 
You can try this java code in a function by taking the input value and returning the replaced value as per your requirement.
Hope this will help you to achieve your requirement.

Hi Rama,

Thanks for posting on PSC.

There isn't any OOTB rules available to get your work done,

Follow the below steps:-

1. Create a custom Edit Input rule, say "NumbersOnly".

Add code:-

// Remove everything except numbers.
 
StringBuffer sbuf = new StringBuffer(theValue.length());
char c ;
  
for (int i = 0; i < theValue.length(); i++ )
{
c = theValue.charAt(i);
if (!Character.isLetter(c) ) {
         sbuf.append(c);
    }
}
 
theValue = sbuf.toString();
 
Save this Edit Input rule.

2. On Advanced Tab of your property which you want to manipulate, add above created Edit Input rule.

Hope it answers your query, kindly notify by marking this post as answered.

Regards,

Asif

Hi Ram,

The below code is working fine, compile and run to see the output.

public class RemoveAlphabets {
 
public static void main(String[] args) {
     String str = "a12.334tyz.78x";
     str = str.replaceAll("[^\\d.]", "");
    System.out.println(str);
}
}
Output is : 12.334.78

I had tested the above code in eclipse and it gave me the expected result Rama.

public class TestCode {
 
public static void main(String[] args) {
String str = "a12334tyz78x";
str = str.replaceAll("[^\\d]", "");
System.out.println(str);
}
 
}
Output: 1233478
