Find Special Characters in Image Name

Hi All,

Request:

1. Need to find special characters or Junk Characters in Links name (i.e., Figure$.eps, abcd?cde.jpeg etc)

2. Links name allows only [a-z] or [A-Z] or [0-9]

3. Links name not allows special characters like (i.e., ?, !, @, $ etc...)

4. White Space also not allowed

Very Urgent Request...

Trying Code is:

var myLinks = app.documents[0].links.everyItem().getElements();
alert(myLinks.length)

for(i=0; i<myLinks.length; i++)
{
    var mySplit = myLinks.name.split(".");
    var myFinal = mySplit[0];
    
    for(k=0; k<myFinal.length; k++)
    {
        if(String(myFinal).match(/[a-z]/g) !=null || String(myFinal).match(/[A-Z]/g) !=null || String(myFinal).match(/[0-9]/) !=null )
        {
            alert(myFinal);
            break;
            }
        
        }
    }

Thanks in Advance
