Regex

Hi All,

I am using regex to get a alphanumeric value from a string . The regex i  used is [A-Za-z0-9] . Please help me on this .

Thanks in advance.

Hi Kali,

The alphanumeric regex accepts if the string is having only alphabets/only numbers/both alphabets and numbers.

I hope there is no regex that returns true for alphanumeric and false for only alphabets and only numbers.

I have tried the below script in the background which returns the alphanumeric string:

var sub = 'This is a sample case for 123AZBzxc';

var subArr = sub.split(' ');

for (var i in subArr) {

    if (new RegExp("^[a-zA-Z0-9]*$").test(subArr[i]) && !(new RegExp("^[A-Za-z]*$").test(subArr[i])) && !(new RegExp("^[0-9]*$").test(subArr[i]))) { //satisfies if the string only alphanumeric

        gs.info(subArr[i]);

    }

}

Hi @Rupanjani , 

var subject ="This is a sample case for 123AZBzxc";

var subjectarray = subject.split(' ');
gs.print(subjectarray);
var rg = new RegExp("^[a-zA-Z0-9]*$");
for(i=0;i>subjectarray.length;i++){
rg.match(subjectarray[i]);
}
gs.print(rg);

When i run this above in the background script i am getting the below as the return value.

 /^[a-zA-Z0-9]*$/

@Steven Bell  : Can you please check the code and let me know where the problem lies. I want to return a alphanumeric value .

Thanks in advance

Hi kali,

Please try the exact code given in background script.

If you are using it in any other scripts, try yo use the if loop mentioned.

If loop gets satisfied, only if the string is alpha-numeric.
