Remove special characters - Groovy Script -SAP HCI/CPI

We had a requirement to remove the special characters in the field in mapping and also remove the prefix "0".

After this if the value starts with 63 or 61 then + should be added at prefix and send to target field

Note: You can find the usage for if condition, replaceAll, startsWith, replaceFirst function, concat, Boolean function

Input: 

"000ew63f@gAH-Je5^%7r/df&6!)78g"

Output:

6357678


Code:

import com.sap.it.api.mapping.*;

def String customFunc(String arg1){

def str5 = ''

def str4 = '+'

// Remove the special characters

       def str2 = arg1.replaceAll("[\\*\\?/()\\-\\^!@_+%.&#a-zA-Z]","")

// remove the leading zero's

def str3 = str2.replaceFirst ("^0*", "")

//condition to check the 63 or 61

if (str3.startsWith("63") || str3.startsWith("61"))

{

  

   str5 = str4.concat(str3)

}

return str5

}

or 

import com.sap.it.api.mapping.*;

def String customFunc(String arg1, String arg2, String arg3){

def len1

def len2

len1 = arg1.length()

len2 = arg2.length()

if( len1 > 0 )

{

def str2 = arg1.replaceAll("[\\*\\?/()\\-\\^!@_+%.&#a-zA-Z]","")

def str3 = str2.replaceFirst ("^0*", "")

def str5

def str6

def str7

if (str3.startsWith("63") || str3.startsWith("61"))

{

    def str4 = "+"

    str5 = str4.concat(str3)

return str5  

}

else 

{

    if( (len2 == 0) && (arg3 == "Melbourne" || arg3 == "Sydney"  )){

  str6 = "+61"

  str7 = str6.concat(str3)

  return str7

    }

}

}

else

{

                return arg1

}

}
